摘　　要：运用热重法对煤单独热解以及煤与生物质共热解特性及反应动力学进行了研究。研究了生物质的加入对煤热解特性的影响,重点考查了升温速率和掺混比对生物质与煤共热解特性的影响。生物质的加入能有效促进煤中挥发分的析出。采用Coats-Redfern法求出了煤热解及生物质与煤共热解时的动力学参数,煤与生物质共热解表观活化能变化范围在20~30 k J/mol。The pyrolysis characteristics and reaction kinetics of coal pyrolysis and co-pyrolysis of coal and biomass were studied by thermogravimetry.The effects of heating rate and mixing ratio on the co-pyrolysis of biomass and coal were investigated,and the effects of biomass on the pyrolysis characteristics of coal were studied.It was shown that the addition of biomass can promote the precipitation of volatile matter in coal effectively.The kinetic parameters of coal pyrolysis and biomass and coal co-pyrolysis were obtained by Coats-Redfern method.The variation range of apparent activation energy of coal and biomass co-pyrolysis was 20~30 kJ/mol.
