Abstract

The invention provides a liquefied gas hydrogenating, olefin content decreasing and desulfurizing catalyst and a preparation method thereof. The catalyst comprises a carrier and activated substances, the carrier adopts F-modified Al2O3-TiO2 composite oxides, activated substances comprise molybdenum, nickel and cobalt, the molybdenum is a main component, and the nickel and the cobalt are auxiliary components. The preparation method of the catalyst comprises a process for preparing a modified Al2O3-TiO2 compound oxide carrier and a process for preparing the liquefied gas hydrogenating, olefin content decreasing and desulfurizing catalyst by a co-impregnation method. The liquefied gas hydrogenating, olefin content decreasing and desulfurizing catalyst has the advantages of double functions of resisting to sulfur-poisoning and hydrogenating, olefin content decreasing and desulfurizing of a traditional molybdenum catalyst, simultaneously, low-temperature and low-pressure activity is good, deeply hydrogenating saturability is high, and activity is stable.

Description

Technical field

[0001] The invention relates to the technical field of hydrogenation catalysts, and is particularly suitable for catalysts required for the hydrogenation reaction of olefins and organic sulfur in liquefied gas and C5 and other light hydrocarbon raw materials, and a preparation method thereof. Background technique

[0002] In recent years, with the rapid improvement of my country’s crude oil processing capacity and the continuous increase of ethylene production, C4 resources as a by-product of petrochemical industry are also expanding, and their total production has exceeded 3.0Mt / a; on the other hand, the production of ethylene The continuous increase has caused the tension of ethylene raw materials, and the subject of liquefied gas as the raw material for ethylene cracking has emerged. The liquefied gas after superposition or aromatization has 1 to 5% residual olefins. If it is directly used as raw material for ethylene cracking without treatment, olefins will und...
