| 英文摘要 | hierarchically porous sapo-11 zeolite (h-sapo-11) is rationally synthesized from a starting silicoaluminophosphate gel in the presence of polyhexamethylene biguanidine as a mesoscale template. the sample is well characterized by xrd, n-2 sorption, sem, tem, nmr, xps, nh3-tpd, and tg techniques. the results show that the sample obtained has good crystallinity, hierarchical porosity (mesopores at ca. 10 nm and macropores at ca. 50-200 nm), high bet surface area (226 m(2)/g), large pore volume (0.25 cm(3)/g), and abundant medium and strong acidic sites (0.36 mmol/g). after loading pt (0.5 wt.%) on h-sapo-11 by using wet impregnation method, catalytic hydroisomerization tests of n-dodecane show that the hierarchical pt/sapo-11 zeolite exhibits high conversion of n-dodecane and enhanced selectivity for branched products as well as reduced selectivity for cracking products, compared with conventional pt/sapo-11 zeolite. this phenomenon is reasonably attributed to the presence of hierarchical porosity, which is favorable for access of reactants on catalytically active sites. the improvement in catalytic performance in long-chain paraffin hydroisomerization over pt/sapo-11-based catalyst is of great importance for its industrial applications in the future.
