摘　　要：制备了系列含β、ZSM-22分子筛的改性F-T合成催化剂,考察了分子筛类型及分子筛不同含量对F-T合成催化性能、产物分布的影响。结果表明,分子筛的加入均能明显提高F-T合成产物中的异构烃含量。分子筛的酸性和结构影响异构烃的选择性及催化剂的活性稳定性。Fischer-Tropsch synthesis catalyst modified byβ,ZSM-22 zeolites were prepared.Effects of type and content of zeolites on catalytic activity,selectivity and product distribution were investigated.Results indicate content of isoparaffins in product of traditional Fischer-Tropsch synthesis is increased significantly at the presence of metal/zeolite catalysts.Acidic and structural properties of zeolites influence selectivity of isoparaffins and activity/stability of activity.
