Description

technical field [0001] The invention belongs to the technical field of catalyst preparation, and in particular relates to a mesoporous composite copper catalyst for producing carbon monoxide from methanol and a preparation method and application thereof. Background technique [0002] As the main component of synthesis gas and various coal gases, carbon monoxide is an important raw material for the synthesis of basic organic chemical products and intermediates. It can produce almost all basic chemicals, such as alcohols, acids, anhydrides, esters, aldehydes, ethers, Amines, alkanes and alkenes etc. At the same time, various homogeneous reaction catalysts required for organic chemical production can be prepared by utilizing the properties of carbon monoxide and transition metals to generate metal carbonyls or metal carbonyl derivatives. [0003] The target products of methanol cracking to carbon monoxide technology are CO and H 2 , the reaction temperature is 200-300 ° C, an...
