摘要
在小型常压流化床内采用多孔介质为床料,对生物质进行了空气、空气-水蒸汽气化实验并与普通工业用砂为床料的气化结果进行了对比,分析不同气化介质、温度及流量时多孔床料对生物质产气特性的影响。实验结果表明:产气中可燃气含量随气化温度升高而增大,流量对生物质气化影响存在最佳范围。与普通床料相比,多孔床料对H_2和CO的生成以及对低碳氢化合物(C_XH_Y)的催化裂解有较强的促进作用。
Biomass gasification under air and air-stream in a pilot fluidized bed, with porous media as bed material, was studied. Compared with the consequence of common industry sand bed material gasification, the characteristic effect of porous media on biomass gasification under different gasification medias, temperature and flux was analyzed in the paper. The test results show that the content of combustible gas and reaction activity were enlarged along with the rise of gasification temperature, the flux effect on gasification have an optimal range. And compared with common bed material, the porous medias have evidently promoting function on HE and CO product and hydrocarbon （CXHY） catalyze pyrogenation in biomass product gas.
