Here's an interesting clip from http://www.eere.energy.gov/hydrogenandfuelcells/pdfs/25315hh.pdf
Results In earlier work we reported the ease of gasification of glycerol in supercritical water.Table 2 confirms the earlier result.In it we see that the hydrogen content of the gas increases from 38% to 51 %after 3.45 hr,while the methane content decreases from 20%to 11 %.During this time the total gas yield increased from 1.18 to 1.6 L/g and all the carbon in the feedstock was converted to gas.The increasing gas yield is due to the consumption of water and methane by the steam reforming reaction.Evidently this reaction is catalyzed by the reactor's wall and/or the carbon catalyst,which become more active (i.e."seasoned")as time passes.When the gas yield reached a steady state,the feed was switched and sawdust paste was fed to the reactor for 4 hours.After this,glycerol was again fed to the reactor.Table 2 shows that the sawdust paste causes the reactor's wall and/or the carbon catalyst to lose some activity towards the steam reforming reaction. The waste product generated by the commercial production of biodiesel fuel contains glycerol and methanol.We prepared a mixture of these two alcohols with a composition identical to that of the industrial waste.The gas produced from this mixture (see Table 3)is very rich in hydrogen,and the yield (2.05 L/g)is high.The water leaving the reactor was clean with a pH of 4-5.Evidently,this waste product is a perfect feedstock for hydrogen production. ------------------------ Yahoo!
