<DIV><BR></DIV><BR>Hi,<BR><BR>First of all, there are at least two different
types of biofuel:<BR>First Generation: agricultural feedstock, which is
converted by means of biochemical processes (i.e., digestion) -->
Biogas<BR>Second Generation: woody biomass that is converted via
thermochemical converiosn into a producer or so-calles syngas
(Gasification).<BR>Thus, if your goal is to produce Methan or Natural Gas
substite for a gas engine or transportation fuel you have different options.
But you need to know what is your feedstock (dry , wet, digestable or not
digestable such as wood):<BR>If you have a rather dry feedstock you can go for
steam gasifiaction (no air, means no Nitrogen). The produced syngas you can
catalytilcally convert to CH4, CO2 and H2O. Prior to the methanation process
you need to remove the sulphur since it is deactivating your catalyts. H2O and
CO2 can then be removed. This process has been investiaget by the Paul
Scherrer Institiute in Switzerland (www.psi.ch and
www.bio-sng.com).<BR>Removal of nitrogen is too expensive, thus you should
avoid feeding it into your process. 2 vol% to max 5vol% N2 in the methan rich
gas is acceptable.<BR><BR>Regards,<BR><BR>Jan<BR><BR>

[Gasification] back to gasification<BR><BR>Dear A.D Karve
<DIV> </DIV>
<DIV> One of the project we have been studying is
based on the IGT,Instuite Gas technology patented process
called Biotherm , in which the wood gas or syngqs
can be passed into the biodigestor, in which CO and
Hydrogen can be converted into methane ; the NOX
.COX, SOX removed via simple known wet or dry process using
activated charcoal and lime ; the methane is then compressed.The N
can be removed as ammonia,as this can be very toxic to bio
methane bacteria; Syngas obtained via pyrogas can reduce this N2 problem and
complexity.Thus pyrogas technology has more potential than
wood gas technology</DIV>
<DIV> </DIV>
<DIV> we are studying how to make this complex process into simple
innovative process to make possible charcoal and methane economy
which is practiced in the developed country in big scale
can be made possible in developing village level technology too
in small scale ,The project is yet in design stage to reduce CO2 to use as
liquid fertilizer too increasing the
calorific valued the compressed biogas.</DIV>

class=gmail_quote>Dear List,<BR>We are already using, in India, wood gas
made from agricultural waste<BR>to run stationary internal combustion
engines. But, for using it as<BR>automobile fuel, it would have to be
filled into cylinders, for which<BR>the nitrogen in the wood gas would

calorfiic value. Does anybody have<BR>a suggestion as to how this can be
