Title:
MICRO-INTERFACE REACTION SYSTEM AND METHOD OF COAL-TO-ETHANOL
Document Type and Number:
WIPO Patent Application WO/2022/011871
Kind Code:
A1
Abstract:
The present invention relates to 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 includes 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 includes a carbonylation reactor, and the outer side of the carbonylation reactor is provided with a first micro-interface generator. In the first micro-interface generator, dimethyl ether separated from the rectification tower by rectification is introduced, and at the same time carbon monoxide is introduced, and same is then dispersed and crushed by means of the first micro-interface generator and then enters the carbonylation reactor for reaction. The micro-interface reaction system reduces the energy consumption, reduces the reaction temperature, improves the utilization rate of the raw materials, and also effectively improves the productivity.
