Straw biomass is made into fuel by liquefaction or solidification, which can be used for direct heating, or it can be made into clean straw coal, etc. Straw charcoal is a new type of renewable energy from biomass, which is environmentally friendly and clean. It is much 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 seam gas and natural gas in people's lives still requires vigorous advertising and promotion.
2.3 Transport energy
The main components of straw are carbon, hydrogen, oxygen and others elements. The organic components are mainly cellulose and hemicellulose, followed by lignin, proteins and fats.
, ashes, etc. Biofuels processed from straw, such as bioethanol and biodiesel, are used as transportation energy compared to fossil fuels such as oil, natural gas and coal
. The biggest feature is that they can be regenerative and more environmentally friendly. Internationally, energy biotransport technology is relatively mature. The main ways are: fermentation of cereals, straw, other plants, etc. to produce ethanol, automobile oil, ethylene, non-toxic solvents and hundreds of chemicals. and raw material products, etc. ; research on straw transport energy technology in China started late, but it is becoming increasingly popularus mature, and some become small-scale and commercialized.
3 Straw biomass energy application technology
Straw biomass energy application technology mainly includes straw biogas (biogasification ), solidified straw fuel, gasification by pyrolysis of straw and energy production by direct combustion and straw retort.
