摘　　要：采用过量浸渍法制备Co/Hβ-沸石FT合成催化剂(Co负载质量分数为10%),并对其FT合成反应活性、产物选择性以及稳定性进行考查。实验结果表明,在一定反应条件下,制备的Co/Hβ催化剂具有较好的活性和稳定性;一定浓度的柠檬酸对Hβ沸石进行改性,会对Co/Hβ催化剂的FT反应活性及产物选择性产生一定影响。Co/H β-zeolite catalyst for Fischer-Tropsch synthesis was prepared by impregnation,its catalytic performances for FT reaction,such as catalytic activity,stability and products selectivity were investigated.The experimental results show that the Co/H β-zeolite catalyst with 10% Co-loading（mass fraction） has good FT reaction activity and stability,and modification of the Co/H β-zeolite catalyst with 0.1mol/L critic acid has great influence on its FT reaction activity and products selectivity
