我国低劣生物质种类丰富、总量巨大,其中每年产生的城市垃圾、秸秆、禽畜粪便等低劣生物质达到3×10^9t之多,大量的原料基础为我国生物甲烷开发和利用提供了良好的条件。本文介绍低劣生物质制备生物甲烷在我国的发展现状,发展存在的问题和对策,重点介绍以生物甲烷为核心的一种可以使生物甲烷更加清洁高效、利用全面的环保型能源产业新模式。最后通过能源产业链延伸对生物甲烷利用的广阔前景进行了展望。
Low-valued biomass is very rich and tremendous in China, such as municipal waste, straw and livestock manure which are more than 3.0 billion tons in one year. This low-valued biomass provide a good condition for development of biomethane. In this paper,we introduced the development status,problems and countermeasures of biomethane in China. We also introduced a new pattern of environmentally friendly energy industry to biological energy as the core could make use of biomethane more cleanly and effective comprehensively. At last, the prospects of biomethane utilization was discussed through the extension of energy industry chain.
