中文摘要	采用管式炉对红松锯屑快速热解制取富氢气体进行了实验研究,分析了反应器温度、物料粒径和催化剂对热解产物组成的影响。结果表明高温能加快生物质快速热解进程,减少炭和焦油生成量,利于富氢气体的生成,800℃时气态产物比例可达56.9 wt.%,气态产物中H2体积分数由4.3%(500℃下)上升至17.2%,H2+CO体积分数达68.3%。小粒径能增大热解气态产物的比例,但对气态产物组成的影响很小,这可能与红松锯屑本身质地疏松有关。以与生物质直接混合方式添加的煅烧白云石能使热解产物中H2含量增加,但造成产气过程变缓,炭生成量增多,富氢气体总产量未能得到提高。; This paper deals with the fast pyrolysis of pine sawdust in a tube furnace.Interests are especially focused on the yield of hydrogen-rich gas and related reaction conditions such as temperature,particle size of feedstock and catalyst.Results show that a higher temperature can quicken the fast pyrolysis process and reduce the yields of solid and liquid,which is in favor of the production of hydrogen-rich gas.When at 800 ℃,the gas yield reaches 56.9% by mass,H2 content of gas product 17.2 vol.%(compared with 4.3% at 500 ℃),H2+CO content 68.3 vol.%.Smaller particle can also result in a larger gas yield proportion,but the effect of particle size on gas composition is not so prominent,which may be related with the loose texture of sawdust particles.Calcined dolomite increased the H2 content in gas product when added by direct mix with sawdust,but the reaction process was slowed down and more char remained,and the total gas yield was not improved.
