载体对负载型NiSn催化剂丙烷脱氢性能的影响
Propane dehydrogenation over NiSn-based catalysts
摘要
Abstract
In this paper, we studied the effects of supports, such as SiO2 , MgO, Al2 O3 and MgAl2 O4 , on the performance of supported NiSn catalyst for propane dehydrogenation. NH3 temperature-programmed desorption, H2 temperature-programmed reduction were applied for the characterization of the catalysts. The results show that SiO2 with large specific surface area and large pore size can achieve good contact between catalyst and reactants, leading to a high content of Ni2. 67 Sn2 alloy and a reduced diffusion resistance, In addition, their weak acid improve dehydrogenation activity and propene selectivity.关键词
