Title:
CATALYST, PREPARATION METHOD THEREFOR AND METHOD FOR PREPARING 2,5-FURANDICARBOXYLIC ACID FROM CATALYST
Document Type and Number:
WIPO Patent Application WO/2023/125067
Kind Code:
A1
Abstract:
A CoCu xO y catalyst, the molar ratio of Co, Cu and O thereof being 1:(0.2-1):(3-4). A preparation method of the catalyst comprises: dropwise adding a solution of an oxidizing agent and an initiator into a mixed aqueous solution of copper nitrate and cobalt nitrate, filtering the mixed solution after ageing to obtain a black cake-like precipitate, and calcining the precipitate at 180℃ to obtain the CoCu xO y catalyst. The present invention also provides a method for preparing 2,5-furandicarboxylic acid from the CoCu xO y catalyst prepared by said method. The preparation method of the CoCu xO y catalyst in the present invention has simple and convenient operations and mild conditions; the prepared catalyst has high catalytic efficiency; and using the catalyst for preparing 2,5-furandicarboxylic acid is characterized by high efficiency, easy separation, low costs, less pollution and the like.
