生物质能的热化学转化技术

生物质能源是未来替代化石资源的丰富和可再生清洁能源之一,它具有二氧化碳中性。生物质的热化学转化可以形成固、液、气3种形态的生物质能源,用以提供热能和动力。对生物质热化学转化中的燃烧、气化、液化和热解技术进行阐述,同时提出生物质热值低、运输贮存不易、反应副产物难分离和政策、资金投入力度仍需加大等问题,对生物质能源发展和研究进行展望。

Study on Biomass Thermo-Chemical Conversion Techniques

Biomass energy, as is clean and carbon dioxide neutral, is one of the renewable abundant source to replace fossil fuels in future. Biomass thermo-chemical processes can be converted into bio-fuels with the forms of solid, liquid and gas, which can be used to provide heat energy and power. Some advanced thermo-ehemical processes, including combustion, gasification, liquefac- tion and pyrolysis were introduced in this paper. Besides, the problems such as low calorific value of biomass, difficult to transport and storage, hard to separate reaction by-products and demanding to increase policy as well as capital investment were all discussed. Then the further development and research of bio-fuels was prospected.
