【摘要】 根据产气量为20m3/h的热解炉,以玉米秸秆颗粒为生物质原料,对额定功率为10kW的燃气发电系统及其相关的焦油裂解装置进行了研究,得出玉米秸秆颗粒在热解温度为470℃左右时,燃气的热值最高,以煅烧的白云石和镍基催化剂组成的焦油裂解装置,在催化裂解温度为850℃时,可达97%以上的焦油裂解率。结合对热解气副产物生物质炭的分析,得出了生物质热解利用系统的产出能量大概分布,为生物质能源的高效综合利用提供一定的参考。更多还原

【Abstract】 In the paper,according to pyrolysis oven with 20m3/h biomass gas production rate,corn straw kernel is taken as biomass feedstock,biomass gas generation system with 10kW nominal power output and it’s tar cracking equipment are studied. The result shows that the heat value of biomass gas can be maximum at about 470℃. Conversion of tar catalytic cracking is more than 97% at 850℃ with equipment made of calcined dolomite and Ni base catalyst. Combined with analysis of by-product biomass char of pyrolysis gas,energy general distribution about biomass pyrolysis utilization system is educed,some references may be provided for high efficiency and comprehensive utilization of biomass.更多还原
