Title:
ALKALI-MODIFIED COMPOSITE CATALYST AND METHOD FOR PREPARING ETHYLENE BY HYDROGENATION OF CARBON MONOXIDE
Document Type and Number:
WIPO Patent Application WO/2019/144954
Kind Code:
A1
Abstract:
Disclosed are an alkali-modified composite catalyst and a method for preparing ethylene by the hydrogenation of carbon monoxide. A conversion reaction is carried out on a fixed bed or a moving bed using a mixed gas of carbon monoxide and hydrogen as a reaction raw material, wherein the catalyst used is a composite catalyst compounded from a component I and a component II by means of mechanical mixing. The active component of the component I is a metallic oxide, and the component II is a molecular sieve of an organic alkali-modified MOR structure, wherein the organic alkali is a heterocyclic compound, and the modification treatment is to disperse the organic alkali into a B acid site within a 12-membered ring pore channel of the molecular sieve; and the weight ratio of the active component of the component I and the component II is 0.1:20. The reaction has a very high product yield and selectivity, wherein the selectivity of a side product of methane is very low and the selectivity and the space-time yield of ethylene are significantly improved, and the reaction has very bright application prospects.
