Abstract

The invention discloses a selective hydrogenation catalyst for unsaturated ketone. By taking a highly dispersed metal oxide compounded nitrogen doped porous carbon material as a carrier, noble metal particles are attached to the nitrogen doped porous carbon material, wherein the noble metal particles is 0.1-20% with respect to the mass content of the nitrogen doped porous carbon material. The invention also discloses a preparation method and an application of the catalyst. The metal oxide in the catalyst is uniformly distributed in and compactly combined with the nitrogen doped porous carbon material. The nano noble metal particles are dispersed highly. The experimental method is simple. The raw materials are very wide in source and high in sustainability, so that scaled production can beachieved. The catalyst shows excellent catalytic activity and stability in selective hydrogenation reaction of carbon-carbon double bonds of a key intermediate in a vitamin industrial chain.

Description

technical field

[0001] The invention belongs to the technical field of catalysts, and in particular relates to a catalyst for selective hydrogenation of unsaturated ketones, a preparation method thereof, and an application in the selective hydrogenation reaction of carbon-carbon double bonds of key intermediates in the vitamin industry chain. Background technique

[0002] More than 80% of all kinds of chemicals used in life are produced through specific catalytic processes. At the heart of the catalytic process is the catalyst. However, heterogeneous catalysts have attracted extensive attention due to their ease of operation. As an important representative of heterogeneous catalysts, supported metal nanocatalysts have a wide range of applications. Dispersing the active metal on a carrier can greatly reduce the amount of metal used while achieving the same catalytic effect. Carbon material is an ideal catalyst carrier because of its high thermal and electrical conductivity...
