Controllable immobilization of catalysts in microreactor is the crux for the industrial application of micro-chemical technology. In this project, employed the hollow fiber ceramic (HFC) tube as microchannel, the growth process of zeolite membrane was investigated and optimized by flow method with introduced NaA and ZSM-5 seed layers as the active sites. An excellent and controllable preparation method of single zeolite membrane and multilayer composite membrane in microchannel reactors was achieved; Based on the characteristic sieving and adjustable acid-base performances of zeolites, a bifunctional HZSM-5/NaA composite membrane microchannel reactor with acid catalysis & separation was built by ion exchange; With the aid of mass transfer enhancement in microreactor and zeolite membrane’ selective permeation performances, the efficient synthesis of solketal by acetone and glycerol was then studied in this microreactor with integrated reaction and separation process. The kinetics in microchannel reactor, the acid catalytic performances of zeolite membrane, and the influence law of selective removal of water to the reaction equilibrium process were all investigated. This project devised a bifunctional microchannel reactor which integrated reaction and separation process for efficient synthesis of solketal-a useful route of glycerol which was by-produced in bio-fuels.
