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<o:p></o:p></span></p><div class=MsoNormal align=center style='margin-left:.5in;text-align:center'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'><hr size=2 width="100%" align=center></span></div><p class=MsoNormal style='margin-left:.5in'><b><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'>Von:</span></b><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> "Pannirselvam P.V" <pannirbr@gmail.com><br><b>Gesendet:</b> May 31, 2011 12:46:54 PM<br><b>An:</b> "Discussion of biomass pyrolysis and gasification" <gasification@lists.bioenergylists.org><br><b>Betreff:</b> Re: [Gasification] back to gasification<br><br>Dear A.D Karve <o:p></o:p></span></p><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> <o:p></o:p></span></p></div><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> 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<o:p></o:p></span></p></div><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> <o:p></o:p></span></p></div><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> 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.<o:p></o:p></span></p></div><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> <o:p></o:p></span></p></div><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'>Yours truely<o:p></o:p></span></p></div><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'>Pannirselvam<o:p></o:p></span></p></div><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> <o:p></o:p></span></p></div><div><p class=MsoNormal style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom:12.0pt;margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'> <o:p></o:p></span></p><div><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'>On Mon, May 30, 2011 at 11:01 PM, Anand Karve <<a href="mailto:adkarve@gmail.com">adkarve@gmail.com</a>> wrote:<o:p></o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'>Dear List,<br>We are already using, in India, wood gas made from agricultural waste<br>to run stationary internal combustion engines.
