Abstract

This thesis covers the catalytic and process study of the selective hydrogenation reactions, in order to improve the alkene selectivity, to decrease the catalyst cost, and to stabilize the temperature control. Pd–Ni bimetallic catalysts were studied from fundamental to application. Based on the better performance of Ni modification, a non-precious metal catalyst was designed. Furthermore, a novel process of liquid-phase hydrogenation was investigated by coupling the selective absorption in the liquid phase to the selective hydrogenation on the catalyst surface. The novel process was optimized, and the concept of a multi-stage slurry reactor was proposed.
