Straw biomass can be made into fuel through liquefaction or solidification, which can be used for direct heating, or it can be made into straw clean coal, etc. Straw coal is a new type of biomass renewable energy. It is environmentally friendly and clean. It is far lower than the cost and market price of raw coal. It has a wide range of applications and can replace wood
firewood, Raw coal and liquefied gas are widely used in domestic stoves, heating furnaces, hot water boilers, industrial boilers, etc. However, how to make biomass fuels as popular as coal, coal gas and natural gas in people's lives still requires vigorous publicity and promotion.
2.3 Transportation Energy
The main components of straw are carbon, hydrogen, oxygen and other elements. The organic components are mainly cellulose and hemicellulose, followed by lignin, protein, and fat.
, ash, etc. Biofuels converted from straw, such as bioethanol and biodiesel, are used as transportation energy. Compared with fossil fuels such as oil, natural gas and coal
, the biggest feature is that they can Regenerative and more environmentally friendly. Internationally, biotransportation energy technology is relatively mature. The main routes are: fermentation of grains, straw
straws, other plants, etc. to produce ethanol-vehicle oil, ethylene, non-toxic solvents and hundreds of chemical and raw material products, etc. ;my country's straw transportation energy technology research started late, but it is becoming increasingly mature, and some are becoming small-scale and commercialized.
3 Straw biomass energy application technology
Straw biomass energy application technology mainly includes straw biogas (biogasification), straw solidified fuel, straw pyrolysis gasification, Direct combustion power generation
and straw retorting.
