Title:
REACTION SYSTEM AND METHOD FOR COAL-TO-ETHANOL
Document Type and Number:
WIPO Patent Application WO/2022/011870
Kind Code:
A1
Abstract:
Provided are a reaction system and method for coal-to-ethanol. The reaction system comprises a methanol-to-dimethyl ether reaction unit and a dimethyl ether-to-ethanol reaction unit which are connected in sequence, wherein the methanol is prepared from the gasification of coal. The methanol-to-dimethyl ether reaction unit comprises a dimethyl ether reactor. Methanol is introduced into the dimethyl ether reactor for a vapor-phase catalytic dehydration reaction. The dimethyl ether-to-ethanol reaction unit comprises a carbonylation reactor, and the outer side of the carbonylation reactor is provided with a first micro-interface generator. Dimethyl ether, which is separated from the stripping column, and carbon monoxide are introduced into the first micro-interface generator, and same are then dispersed and crushed by means of the first micro-interface generator and then enter the carbonylation reactor for a reaction. The reaction system provided by the present invention reduces the energy consumption, reduces the reaction temperature, improves the utilization rate of the raw materials, and also effectively improves the productivity.
