摘要
Abstract
Pt/Hβ and Pd/Hβ catalysts were prepared by incipient wet impregnation method with shaped Hp zeolite as the support. Their catalytic performances in n-butane isomerization were studied in a continuous flow microreactor under the conditions of reaction pressure 2. 0 Mpa, reaction temperature 300 -500℃, H2/C mole ratio 3.0 and LHSV 1.25 h-1. The catalysts were characterized by means of N2 adsorption-desorption and SEM. The results showed that the isomerization performance of Pd/Hp catalyst was better than that of Pt/Hp catalyst at 350 tand quite the contrary at 400 t. Under reaction temperature 400 t and appropriate Pt loading on Pt/Hp catalyst 0. 6% (w), its catalytic performance was best, and the conversion of n-butane and the selectivity to I-butane could reach 65.6% and 55. 6% respectively; at Pd loading on Pd/Hp catalyst 0. 3% (w), its catalytic performance was best, the conversion of n-butane and the selectivity to /-butane were 64. 6% and 44. 8% respectively. The performances of the Pt/Hp and Pd/Hp catalysts could were improved by addition of Cu, Sn and Zn additives.关键词
