生物质主要指秸秆、谷壳、速生林和林业加工废弃物等,据估计我国资源总量不低于10亿吨/年,其中各类秸秆和谷壳的年产量不低于7亿吨,约合2至3亿吨石油当量。生物质能源的特点是可再生和与环境友好,它除了直接使用之外,还可以采用热降解和生物降解的措施转化为液体燃料。
Biomass mainly refers to straw, chaff, fast-growing forest and forestry processing waste, etc. It is estimated that the total amount of resources in China is not less than 1 billion tons / year, of which the annual output of various types of straw and chaff is no less than 700 million tons, About 200 million to 300 million tons of oil equivalent. Bioenergy is characterized by its ability to be renewable and environmentally friendly. In addition to its direct use, biomass energy can be converted to liquid fuels by thermal and biodegradability measures.
