Title: SELECTIVE HYDROGENATION CATALYST, METHOD FOR PREPARING SAME, AND CATALYTIC EVALUATION METHOD IN GENERATION OF ISOBUTYRALDEHYDE
Abstract:
A selective hydrogenation catalyst, a method for preparing same, and a catalytic evaluation method in generation of isobutyraldehyde. The selective hydrogenation catalyst consists of two parts, i.e., a carrier and an active component. The active component comprises a precious metal material and a non-precious metal material. The carrier is one of fumed silica, precipitated silica, aluminum oxide, carbon nitride, and titanium dioxide. The precious metal material is precious metal Ir. The non-precious metal material is any one of non-precious metals Mo, W, Ni, Co, Sm, Ce, and Re. The atomic ratio of the non-precious metal material to the precious metal material is 0.8-5. The catalyst can be used for selectively hydrogenating methacrolein to generate isobutyraldehyde under a mild reaction condition and in water.
