Gaseous Biofuels, such as biomass gasified gas, biogas and H2, refer to gas fuels produced by biomass pyrolysis and redox reaction or through anaerobic fermentation of microbes and decomposition. It belongs to renewable biomass energy. With the reduction of the fossil energy, people should develop the biomass energy relying mainly on energy plant.
There are two ways to produce gaseous biofuels: one is the combustible gas produced by incomplete combustion and pyrolysis of biomass under the condition of high temperature and anoxic condition, such as the woodchip gas, straw gas, and rice husk gas produced by agricultural and forestry waste, whose main components are CO, H2, N2, etc. The other is biogas, which is produced by anaerobic bacteria under anaerobic conditions, such as straw, sewage sludge, livestock manure, food waste, etc., whose main components are CH4, CO2, etc.
Biomass, including all animals, plants, and microorganisms, refers to various organisms formed by photosynthesis, utilizing atmosphere, water and land. Biomass resources mainly include Animal fat, agricultural and forestry crops, aquatic algae, photosynthetic microorganisms, agricultural and forestry product waste, municipal waste, and livestock waste. All these can be used to produce liquid biofuels, gaseous biofuels or solid fuels.
