Promotion effect of sulfur impurity in alumina support on propane dehydrogenation
文献摘要:
Alumina materials are widely applied either as a catalyst or support in various industrial catalytic pro-cesses.Impurities in alumina that are unfriendly to catalytic performance are inevitably present during the production processes.Facing this problem,we here report that the use of sulfur-containing alumina as the support can generate active alumina-supported platinum catalyst,which exhibits superior propy-lene selectivity and anti-coking ability during propane dehydrogenation.It demonstrated that the sulfur impurity in alumina is not entirely detrimental.During the reduction process,the formation of gas-phase sulfur species increased the electrons and poisoned unsaturated sites of platinum particles.The sulfur impurity in alumina can be removed through a hydrogen reduction process,and the degree of desulfur-ization is correlated with the operating temperature.This study demonstrated that the rational use of impurity will contribute to the design of a catalyst with high reactivity for potential applications.
