| 英文摘要 | a series of mcm-22/zsm-35 composites has been hydrothermally synthesized and characterized by xrd, sem, particle size distribution analysis, n-2 adsorption and nh3-tpd techniques. pulse and continuous flow reactions were carried out to evaluate the catalytic performances of these composites in aromatization of olefins, respectively. it was found that mcm-22/zsm-35 composites could be rapidly crystallized at 174 degrees c with an optimal gel composition of sio2/al2o3=25, na2o/sio2=0.11, hmi/sio2=0.35, and h2o/sio2=45 (molar ratio), of which the weight ratio of zsm-35 zeolite in the composite relied on the crystallization time. the coexistence of mcm-22 and zsm-35 in the composite (mcm-22/zsm-35=45/55 wt/wt) was observed to exert a notable synergistic effect on the aromatization ability for butene conversion and fcc gasoline updating, possibly due to the intergrowth of some mcm-22 and zsm-35 layers. |
