通过初湿浸渍法负载多种添加剂（Fe、Mg、Mn和Ce）对坡缕石负载镍（Ni/PG）催化剂进行改性。考察了添加剂及其含量对Ni/PG催化剂的活性和焦油裂解H2产率的影响。用X射线衍射和透射电子显微镜对催化剂进行了表征。添加剂的含量影响催化剂的活性和焦油裂解的选择性。Fe对Ni/PG催化剂的焦油转化率和H2产率都有较好的促进作用。提高Ni/PG催化剂的Fe负载量有利于焦油的脱除。
The palygorskite-supported nickel (Ni/PG) catalysts were modified by loading with several additives (Fe, Mg, Mn, and Ce) by incipient wetness impregnation. The effect of the additives and their content on the catalytic activity of Ni/PG and H2yield in tar cracking was investigated. The catalysts were characterized by X-ray diffraction and transmission electron microscopy. The content of the additives affected the catalyst activity and the selectivity in tar cracking. Fe was the best species for promoting the performance of Ni/PG both in tar conversion and H2yield. Increasing the Fe loading amount over the Ni/PG catalyst was favorable for tar removal.
