【摘要】 生物质能源是一种可再生的能源,占世界能源的14%以上,可以有效地替代日渐枯竭的化石能源。生物质热解转化为高能量密度的燃料,不仅可以缓解能源的短缺,还可以减少大气污染,改善生态环境。本文介绍了生物质的分类及其结构组成,并从热解反应起始温度和终止温度以及热解产物组成和分布等方面,阐述了生物质类别、催化剂、热解温度、热解压力、升温速率以及气相滞留期等因素对热解过程的影响。更多还原

【Abstract】 Biomass,which constitutes more than 14 percentage of the world total energy,is a renewable energy source and can effectively substitute conventional fossil fuels.Conversion of biomass through pyrolysis to high energy density fuel will relieve the shortage of energy,reduce the pollution of atmosphere and improve the quality of environment.This article introduced the classification,structure and composition of biomass,expatiated the effects of biomass material,catalyst,temperature,pressure,rate of raising temperature and gas staying time on the process of pyrolysis,including the initial and final temperature of pyrolysis reaction,as well as composition and distribution of pyrolysis products.更多还原
