英文摘要	sucrose was pyrolyzed on gamma alumina surface to prepare carbon covered alumina (cca) material. alumina and cca supported pt-sn catalysts were prepared by the complex impregnation method under vacuum. dehydrogenation of n-octadecane was performed to study the effect of carbon addition, pt loading and sn/pt weight ratio on the catalytic dehydrogenation activity, selectivity and catalyst stability. bet, mercury porosimetry, xrd, co-chemisorption, tpr and tg-dta were used for the carrier and the corresponding catalyst characterization. the results showed that more carbon addition, pt loading and higher sn/pt ratio are propitious to the mono-olefin selectivity and catalyst stability. pt-sn was easily formed on the pt-sn/cca catalysts, especially when the pt loading and sn/pt ratio were very high. to keep optimal dehydrogenation conversion, taking consideration to good selectivity and stability, the carbon content, pt and sn loading of pt-sn/cca catalysts should be 8.37 wt.%, 0.5 wt.% and 3 wt.%, respectively.
