The use of oily organic filter media and maintaining gas temperatures below the dew point can significantly improve gas purity. 4. Chemical Kinetics of Reforming To maximize hydrogen ( H2cap H sub 2 ) yield from biomass-derived methane ( CH4cap C cap H sub 4 ), three primary reforming processes are utilized: Steam Reforming: CH4+H2O→CO+3H2cap C cap H sub 4 plus cap

When using biomass gasifiers, the generated "producer gas" often contains high levels of tar (110–1400 mg/ Nm3cap N m cubed
): Requires 10–12 animals and 150 kg of dung daily; sufficient for cooking for 14–16 persons.
