Method for strengthening mixing and reaction of fluids in micro-reactor

Abstract

A method for strengthening mixing and reaction of fluids in a micro-reactor includes that various fluids flow through a micro-reactor firstly, are mixed in the micro-reactor and complete partial reaction, a mixed fluid including reactants and products is formed, and the mixed fluid flows out of the micro-reactor and then further flows through a tubular reactor filled with an internal component; the micro-reactor has a stacked type parallel structure and has channels with the characteristic scale of 0.1-2 mm; the tubular reactor is directly connected with the micro-reactor, and the internal component is a mesh-structural foam metal, foam ceramic or quartz filler. The additional resistance formed by the tubular reactor is used for strengthening mixing of the fluids in the micro-reactor, and at the same time, the internal component in the tubular reactor can make the mixed fluid further subjected to reaction. The method is suitable for a gas-liquid reaction process and a liquid-liquid reaction process.

Description

technical field [0001] The invention relates to a method for enhancing fluid mixing and reaction, and more particularly, relates to a method for combining a microreactor and a tubular reactor containing internal components for fluid mixing and reaction. Background technique [0002] Microreactor is a kind of chemical process intensification equipment, which has a microchannel structure with a characteristic scale of several microns to several millimeters. According to the mass and heat transfer mechanism of conventional scale, under laminar flow, the mass and heat transfer coefficient is inversely proportional to the characteristic scale. The process is reinforced. The reduction of the characteristic scale also increases the internal specific surface area of ​​the microreactor. When the depth of the microchannel is 1mm, the specific surface area value is 1000m 2 / m 3 , when the depth is 0.1mm, the specific surface area can reach 10000m 2 / m 3 . [0003] The characteris...
