秸秆气化焦油在负载复合金属的HZSM-5分子筛上的催化裂解反应的研究

摘要

对生物质秸秆气化焦油的催化裂解进行了实验研究,用浸渍法在HZSM-5分子筛上负载复合金属制备催化剂,在不同的反应条件下进行实验,发现该催化剂能促进焦油转化为气体可燃成分,对降低焦油含量具有明显的效果.%The experiment on catalytic craking of tar pyrolyzed from biomass on gas component is studied. The HZSM-5 catalysts were modified by loading with several additives by incipient wetness impregnation. In different reaction conditions for experiments , it is found that this catalyst can accelerant the conversion of tar into combustible components , effectively and reduce the content of tar.
