英文摘要	ce-modified alumina carriers with different ce content were prepared by vacuum isovolume impregnation method aiming to improve the n-dodecane catalytic dehydrogenation performance of ptsn/al2o3 catalyst. the support and catalyst were characterized by xrd, n-2 adsorption-desorption, nh3-tpd, h-2-tpr, co-pulse adsorption and tg-dtg. results showed that ce addition decreased the surface acid amount significantly and inhibited the reduction of snox species. besides, ce containing catalyst showed higher n-dodecane dehydrogenation activity and stability and lower coke deposition amount and coke burning temperature. in our study, the optimal ce addition amount for n-dodecane dehydrogenation was 2%.
