MICRO-REACTION APPARATUS AND METHOD FOR PREPARING BIODIESEL BY BASE CATALYSIS

WIPO Patent Application WO/2022/266952

A1

The present application relates to a micro-reaction apparatus and method for preparing biodiesel by base catalysis. The apparatus comprises a feeding system, a micro-reaction device, and a separation device, the feeding system is communicated with the micro-reaction device, and the micro-reaction device is communicated with the separation device; the micro-reaction device comprises a micro-reactor, and the micro-reactor is a micro-dispersion type micro-reactor; in the micro-reaction device, an oil phase and a short-chain alcohol undergo an ester exchange reaction under base catalysis to generate a fatty acid ester and by-product glycerol; the micro-dispersion type reactor has a micro-dispersion structure for dispersing the short-chain alcohol into micron-sized droplets. By adoption of the solution of the present application, the intrinsic safety of the process is improved, the reaction time is greatly shortened, the material flow resistance is smaller, and the system operation pressure is low; the micro-reaction apparatus has a large single-channel treatment capacity which is 10-500 times that of a micro-channel reactor, and has industrial potential.
