Message-ID: <0.3dfb7520.25a0de9d@aol.com>

Dear Tom Reed,
Thanks for the rational article on global warming. I happen to agree
with the concept that increased CO2 may have very little effect upon the
atmosphere for a variety of reasons including it's solubility in the water
vapor which keeps it from accumulating, and the chemical reactivity with
plants which likewise consume it in vast amounts. Agronics, a non-chemical
remineralizing company happens to believe in the "coming ice age" approach
which is the opposite group from the "hothouse" group. However, I believe
that there is very little which man can do other than set off nuclear bombs
around the world to block the sun and create a huge winter, not unlike the
one which took the human population of the earth from 5,000,000 to 100,000
many eons ago from a volcanic eruption in the southern hemisphere. So, I
cannot see a scenario where we can heat up the earth, only cool it down.
We at Agronics remineralize the earth to increase the absorption and
utilization of CO2 and plant growth. That is our contribution to atmospheric
controls and of course, dramatic increases in biomass production through
better nutrition.
As projected, the Y2K bug did not materialize, except that my cell phone
lost it's time and date for a few hours until I moved back into a digital
roaming area, and this computer (Mac iBook) Windows 98 program is not on time
but the Mac program is running smoothly with no bugs and no corrections. The
Win 98 program still runs, but has the wrong time.

We have pyrolysed cocnut husk at 450 deg. cent. and obtained the following
results.
Husk 1000 Gms
Carbon produced 300 Gms

Proximate analysis of carbon is

Moisture 7.1 %
Ash 3.7 %
Volatile matter 37.0 %
Fixed carbon 52.2 %

Are these results along expected lines for husk pyrolysis ?

Dear all

I´m looking for emission factors for eucalyptus fuel production (timber
harvesting, transport etc.)
and gasification, ie. CO2, CH4 and N2O emissions (kg/GJ fuel energy) from
whole production chain
of eucalyptus fuel and from it's gasification (to syngas for methanol
synthesis).

In Finland, we don't have eucalyptus trees, but a lot of boreal forests. I
would like to compare the
greenhouse gas balances of our wood chips production to eucalyptus fuel
production.

Specific energy values and the composition of eucalyptus would also help.
References?

Can anyone help?
Any information is appreciated.

Sincerely,

The pyrolysis results obtained are on expected lines. But to get complete
idea you should also provide the proximate analysis of coconut husk (Not
Rice husk as mentioned in subject). I think the moisture of 7.1% is high
because char may have been exposed to the atmosphere. With yield of 30%
there should hardly be any moisture content in the char.

The results also show that the pyrolysis was only partial which depends
upon temperature or rather temp. profile, time of pyrolysis and size of the
substrate.

Feel free to ask any questions.

Subject: GAS-L: Re: Drying of Sawdust
Message-ID: <aa.523429.25b1d423@cs.com>

Dear Grover et al:

The spiral slide around the chimney is VERY ingenious.

I remember visiting a sawdust pyrolysis plant in which there was a spiral
vibratory chute. With the correct pitch and an off center motor-shaker (or
could be magnetic drive as in vibratory feeders) the sawdust walked UP the
chute. If the chimney was in the middle, the hottest part of the chimney
would contact the wet sawdust, then dry it as it walked UP, and the sawdust
would then exit the chute at the low temperature part of the chimney, thus
avoiding "blue haze" (a counterflow arrangement rather than co-flow).

Nice to hear from Prof. Grover, one of our most ingeneous biomass energy
implementers recently starting a new "midlife" (we hope) career. I hope with
part of the career he will continue to give good advice here at CREST. He
also turned out many good students in biomass.

Yours truly, TOM REED BEF

Sub: Drying of Sawdust

Elsen L. Karstad

One way to dry sawdust without using a fan is to use the heat from the
chimney of the furnace where volatiles are burnt and use its hot surface.

The technique is to provide continuous spiral slide around the chimney with
a slope having an angle of about 500 (equivalent to angle of repose for
sawdust for sliding on an inclined surface). This spiral is covered with
another circular jacket.

The sawdust is added slowly from the top and collected at the bottom. The
extent of drying depends upon its initial moisture content, rate of sawdust
addition, chimney temperature at its wall and the time the saw dust spends on
the spiral (Residence time ). To start with residence time of 20 minutes may
be taken.

If the spiral is flushed with the outer wall of the chimney it also acts as
heat transfer fin conducting heat and supplying it the contact sawdust. The
space between fins should be sufficient and only 10 - 15 % of the volume
should be filled by saw dust. The rest of the empty space is meant for water
vapour and natural convective air to escape. Hope you find this information
useful.

Dear Dr. Hauserman,
I received a virus on another resume' forwarded which was caught on
Kinko's computers when I used a disk to transfer some information there. I
do not believe that it was your resume', but someone else's. I use Mac
computers which are not as affected by virui as MS/IBM systems. I don't even
use the virus checker on my Macs as the incidence rate is so low.
Sincerely,

Subject: GAS-L: THE CHEMICAL HISTORY OF A CANDLE
Message-ID: <35.8967c6.25b85b0f@cs.com>

Dear Firebugs:

Emerson said that everything is made of the same secret stuff. I take this
to mean that the principles are all the same, the applications hide the
principles so we have to be clever to find them.

There was a wildly popular set of Christmas Lectures at the Royal Society in
London, ostensibly for children, but parents fought for seats.

One of the most popular lectures was "The Chemical History of a Candle" given
by Michael Faraday and published as a book in 1861. I had a copy which I
lost many years ago. I came across it in paperback at Amazon.com and have
been re-reading it.

If I want to teach anyone about combustion, I start with the candle - so
familiar, and yet so little understood. I doubt if anyone yet has an exact
model of combustion in the candle, but it is easy to understand qualitatively
all the pieces involved in such a model.

I highly recommend this entertaining book to anyone interested in any aspect
of combustion.

Yours truly, TOM REED BEF PREDD

Dear list members,

I would like to know if any of you have data concerning to bagasse apparent
density. I know it is closely related to the particle size distribution and its
moisture. I've found some values ranging from 110 to 700 kg/m3 (!?!?!) in the
current literature. Can you help me suggesting any references or experimental
values?

Kindly,

Rosilene,
It varies with handling and humidity; I use for design purposes 100 kg/m3. I think
Hugot, in Sugar engineers Handbook, recomends the same value. The 700 kg/m3 value
is for pressed bagasse.
See John Farmer, "The Theory, Design and Operation of Multiple Barreled Screw
Presses for Bagasse", in the ISSCT 16th meeting, page 8.

Rosilene,

We had a bulk density fo 8-11 lb/ft3 (x 16 = 128-176 kg/m3) from the mill in Hawaii (Paia) for our gasification tests. Dry bulk density for chopped bagasse was 6-12 lb/ft3.

Dear list members,

I plan to make a retort for producing charcoal. As may be you know, there is a great amount of pyrolysis gas resulting from the process. One can use this gas in order to get more heat that is needed in the process, adding it to the basic fuel used. Does anyone have an idea on the most efficient gas burner type for me to use? Thank's.

Press Release

microGas Corporation to Demonstrate New Technology for Processing Biosolids
from Wastewater Treatment Plants
January 27, 2000; Bellevue, WA - microGas Corporation, a technology
development company, has recently completed construction of a pilot
demonstration plant for converting wastewater solids into electricity and
ash. The demonstration plant is located near Seattle, Washington at King
County's East Section Reclamation Plant.
This new facility will convert biosolids into a fuel gas suitable for
producing electricity in a reciprocating engine, microturbine or fuel cell.
The low-pressure, sealed system, named SAGE (bioSolids to Ash and Gas
Energy), uses a 2-stage gasification process for volatizing the water and
organic material, and then converting the gas to a clean, high-value fuel.
The SAGE technology minimizes the environmental impact of wastewater
biosolids by substantially reducing the need for land application or other
disposal methods. The SAGE system greatly reduces the need for
transportation of biosolids, thus decreasing the impact on surrounding
communities. In addition to these environmental benefits, the SAGE system
produces electric energy and waste heat that can be used at the wastewater
treatment plant. The King County Department of Natural Resources, GRI, (a
gas industry research organization located in Chicago, Illinois), and
microGas Corporation are sponsoring the SAGE demonstration plant.

Message-ID: <200001280036.TAA09876@smtp10.atl.mindspring.net>

Becca,

I haven't seen the most recent statistics, but for the past decade about 8%
of U.S. electricity has come from biomass. Much of this power is not grid
connected, and relatively few electric utilities have biomass-fired
capacity. Much of the capacity is owned by the paper and pulp industry and
by some of the major timber companies. And the electricity is produced by
combustion of the biomass to power a steam turbine and a generator. Only a
small portion is produced from biogas - probably less than 1%. Relatively
few biogas facilities produce more than 2 MW of power.

Dear Rosilene.

Apparant density of soft biomasses (straw, bagasse, miscantus etc) can vary from 10-20 kg/m3 for bonedry loosse to 300-700 kg/m3 for wet (50-60 % moist) fine chopped biomass.

So in order to get relevant data you have to determin the density of the material you are working with.

Subject: GAS-L: Engines for Producer Gas
Message-ID: <3.0.5.32.20000131094632.0091b8e0@pop3.demon.co.uk>

Dear Group,

I am trying to find an engine manufacturer who has a sympathethic ear to
the needs of companies and organisations who are looking to buy a few
small-scale engines [up to 1MWe] to run on producer gas, but it appears to
be very difficult, based on stories and comments that I have heard. My own
experience is that a company will happily sell you an engine and leave the
rest to you if anything goes wrong.

Interest by major companies, e.g Dale, Caterpillar etc., can be varied and
I do not wish to go down paths many others have trodden.

Can anyone recommend an engine manufacturer who will provide the required
level of technical backup in the modification and operation of an engine?
Does anyone have a detailed, requirement for the gas quality from an
engine manufacturer? I have seen several ''theoretical'' or "postualted"
values for tars and particulates in the gas for an engine, but has anyone
assessed the exact requirements based on long term operational experience?

I am aware of the limited range of interest on behalf of most engine
manufacturers in Europe. Can anyone in North America or elsewhere assist
in pointing me to a suitable company?

Thanks,

Cordner

Dear Dr. Peacocke
I will try to reply to part of your querry about Tar and Particulates in
Producer-gas and its suitability for I C Engines. I have the following
experimental experience:
1. We operated a small single cylinder DI diesel engine under
Producer-gas cum diesel dual-fuel operation following a 16 hour standard
load cycle [0, 20, 40, 60, 80, 100 percent loadings for specified periods
of time, most of the operation being at 100% load and at the end reducing
the load in the same manner and noting down all possible observations.] 20
such cycles amounting to 320 hours were logged. At the end of each cycle a
sample of lubricating oil was drawn for analysis including particulate
accumulation, metal contents and the total base number. The engine was
stripped at the end and wear of different parts; piston, piston
rings, liner, crank and cam shafts and bearings, small and big end
bearings etc was measured. The following conclusions were drawn:
a) The wear rate of certain parts definitely incresed, but
the increase was alarming!! Compression Ratio did not at all
change and the bearing condition was satisfactory.
b) Rate of lubricating oil deterioration did increase, but the
oil consumption remained fairly unchanged. Rescheduling of the
oil change by about 30 to 40% less time could easily take care
of this effect.
c) The main problem arose due to over heating of the fuel
injection nozzle tip and the resultant clogging and coaking of
the nozzle holes. Much more frequent cleaning was warrented.

It is important to mention that this excercise was carried out
on a naturally aspirated engine and therefore the problems
associated with TAR and PARTICULATES and turbocharger were not
encountered.

It was concluded that if the engine is started and warmed up on
diesel mode and stopped also on diesel mode, the problems will
get further reduced.
Tar and Particulates through out this excercise were noted to
be TAR <100mg/cubic meter and Particulate < 50 mg/cubic meter.

WHILE STATING THE VALUES OF TAR AND PARTICULATES IT IS
IMPORTANT TO STATE THAT THE SAME WERE MEASURED USING AN
IMPROVISED THT-APPARATUS WITH ISOKINETIC SAMPLING AND ACETONE
AS THE SOLVENT. METHOD OF MEASUREMENT OF TAR AND PARTUCULATES
IS IMPORTANT TO THE EXTENT THAT IT PROVIDES A DEFINITION OF
TAR. THESE VALUES MIGHT BE VERY DIFFERENT IF SOME OTHER METHOD
IS USED. THERE ARE CASES WHERE MORE OR LESS ALL CONDENSIBLES
ARE TAKEN AS TAR. ACTUALLY WHATEVER CAN BE CONSUMED BY THE
ENGINE WITHOUT HARMING ITS PERFORMANCE; POWER, EMISSIONS,
MAINTENANCE AND LIFE SHOULD NOT BE TERMED AS TAR.
2. One twin cylinder diesel engine has been rebuild as a spark ignition
engine and has been operated on producer gas for over 1000 hours with all
similar monitoring. Results are not very different in this case too.
Details can be provided if required.

Subject: GAS-L: Introducing Mike Antal - and Activated charcoal
Message-ID: <6b.1437010.25c6faad@cs.com>

Stovers and Gasers:

I would like to introduce my friend Dr. Mike Antal, Coral Professor of
Biomass at the University of Hawaii. In my book, he knows more about the
theoretical aspects of pyrolysis and charcoal than most of the rest of us.
He has also developed a process for making charcoal that gives a yield of
40-45%, rather than the 15-25% that most processes give.

He recently visited my home in Golden and we spent a pleasant evening
discussing the subtleties of biomass pyrolysis. He has just sent me two of
his most recent papers that are MUST reading for anyone interested in
activated charcoal (or clean water for developing countries).

"Synthesis of a High-Yield Activated Carbon by Air Gasification of Macadamia
Nut Shell Charcoal", X. Dai and M. Antal Jr., Industrial &Engineering
Chemistry Research, Vol 38, pp 3386-3395, 1999

"Preparation of Activated Carbons from Macadamia Nut Shell and Coconut Shell
by Air Activation", M Tam and M. Antal, Jr., Ibid, Vol 38, pp 4268-4276, 1999.

Mike is achieving surface areas (and iodine numbers) > 1000 m2/g, with yields
over 15%, using air activation.

Charcoal activation is a pain in the butt. In principle, it should be
possible to use air for activation and Mike has found out how to do it.

The three greatest technical challenges for the next century are Clean
Cooking, Clean Power and Clean Water for all of humanity. The solution lies
in our hands.

Yours truly, TOM REED BEF

The references on activated charcoal are interesting. But what is the status
of the HNEI high yield charcoal process ? Are there any commercial plants in
operation ? If yes, please describe.
Thank you.

Dear Tom: thanks for your kind words. I am happy to mail reprints of our
papers to anyone who is interested. Best regards, Michael. P.S. I often
receive requests to post such papers on the web. This is a very
complicated matter with serious copyright issues (that are well defined by
the ACS in the case of ACS publications). At least for the time being, I
will only supply hard copies by mail or fax.
