考察了丙烷在Al_2O_3、MgO、SiO_2及AC(活性炭)等载体负载铂锡催化剂上的脱氢反应性能;结合M(?)ssbauer谱表征结果,讨论了催化剂中锡组份存在状态与丙烷脱氧反应性能间的关系;认识到只有氧化态锡才有利于催化剂性能的改善。
The dehydrogenation reaction of propane over platinum-tin catalysts such as Al 2 O 3, MgO, SiO 2 and AC (activated carbon) was investigated. The results show that the presence of tin in the catalyst is related to the propane deoxygenation The relationship between performance; realized that only the oxidation of tin is conducive to the improvement of catalyst performance.
