Supported efficient hydrogenation catalyst and preparation method thereof

Abstract

The invention discloses a supported efficient hydrogenation catalyst which contains the following materials in parts by weight: 15-20 parts of pretreatment carrier, 4-7 parts of metal precursor, and 14-24 parts of deionized water, wherein the pretreatment carrier is prepared by performing acid treatment on Na-montmorillonite and assisting with an ultrasound microwave combined effect. The inventionalso discloses a preparation method of the catalyst. The catalyst prepared according to the invention has excellent catalytic hydrogenation performance, the supporting capacity of the metal precursorcan be increased by the pretreatment carrier, and meanwhile, an acid site used for promoting the catalytic performance is introduced, and by mutual match of vacuum impregnation and heat preservationunder protection of a hydrogen atmosphere, clustering of active components is effectively avoided, so as to be beneficial to improvement of the activity of the catalyst; and the catalyst can be used for catalytic hydrogeneration reaction, and is wide in market prospect.

Description

Technical field

[0001] The invention relates to the field of chemical engineering, in particular to a supported high-efficiency hydrogenation catalyst and a preparation method thereof. Background technique

[0002] With the continuous development of society and the continuous progress of chemical technology, more and more catalysts are used in chemical production, making important contributions to the development and progress of society. Among them, the hydrogenation catalyst is a catalyst used in the addition of a compound to hydrogen. It is widely used in the fields of medicine, pesticides, cosmetics and toiletry products, adhesives, oil field chemicals, synthetic lubricants, and automotive chemicals. Applications.

[0003] Hydrogenation catalysts are usually prepared by the impregnation method. Because of their simple preparation method and low price, the supported catalyst is formed by impregnating the active components on the porous support in the form of salt solution and pe...
