Abstract

The invention relates to a non-noble metal supported selective hydrogenation catalyst and a preparation method and application thereof. The catalyst comprises a carrier, and a main active component and an auxiliary active component which are loaded on the carrier, wherein the main active component is nickel, and the auxiliary active component is at least one of Mo, La, Ag, Bi, Cu, Nd, Cs, Ce, Zn and Zr; and the active components exist in amorphous forms, the average grain diameter is less than 10 nanometers, and the catalyst is prepared by a micro-emulsion method. The catalyst has evenly distributed active components and high dispersity, and can resist the erosion of poisonous materials of arsenium, sulfur and the like. The catalyst has good hydrogenation performance which is higher than that of the prior level of the conventional non-noble metal catalyst and is close to the level of a noble metal Pd catalyst in the reaction for removing acetylene hydrocarbon through C2 selective hydrogenation.

Description

technical field [0001] The present invention relates to a selective hydrogenation catalyst and its preparation method and application, in particular to a supported non-precious metal catalyst prepared by microemulsion method, its preparation method and its use in unsaturated hydrocarbon selective hydrogenation reaction application. Background technique [0002] Petroleum hydrocarbon cracking to produce ethylene gas usually contains 0.5-2.5% acetylene impurity. The presence of acetylene will poison the polymerization catalyst and affect the quality of polyethylene. Therefore, a small amount of acetylene must be removed before ethylene polymerization. Supported noble metal Pd catalysts are widely studied in this field, and catalysts with Pd as the main active component are widely used in industry. The noble metal Pd-based catalyst is characterized by large processing capacity, high ethylene selectivity, low green oil production and long regeneration cycle. However, since the...
