| Abstract: | Preparation and catalytic performance of skeletal Ni catalysts supported on Al2O3 were studied. The effects of alloy powder/pseudo-boehmite powder mass ratios and calcination temperatures of precursors on surface properties, compressive strength and catalytic performance were investigated. It was found that catalysts prepared by precursors which were molded with alloy powder/pseudo-boehmite powder mass ratio of 4/6 and calcinated at 860 °C in air atmosphere exhibited excellent compressive strength (16.11 N/mm), high dicyclopentadiene conversion (> 95%) and appropriate THDCPD selectivity (> 50%) during 1000-hour evaluation. The operational conditions were obtained as following: T = 120 °C, P = 2.0 MPa, LSHV = 2.0 h? 1 and hydrogen–oil ratio = 300:1. |
