Abstract
A process for preparing a catalyst for selective hydrogenation of acetylene to ethylene, comprises: mixing palladium, gallium, and gold sources, silica, and a solvent to form a suspension, which is then subjected to filtration and drying so as to obtain a catalyst precursor; subjecting the catalyst precursor obtained to a calcination treatment; and subjecting a calcinated product obtained to a reduction reaction in a reducing atmosphere so as to obtain the catalyst. The catalyst prepared according to this process exhibits a high stability and high catalytic performance, and has a large number of active sites uniformly distributed.
