Microchannel gas-liquid reactor with Koch curve structure

Abstract

The invention provides a microchannel gas-liquid reactor with a Koch curve structure. The reactor comprises at least a reactor body, an acrylic plate, a sealing ring and a stainless steel frame, the reactor body is a microchannel plate with the Koch curve structure, and the upper portion of the plate is covered with the transparent acrylic plate and pressed with the stainless steel frame. The combination of a microfluidic technology and a continuous reactor is adopted to effectively and quickly control the flow rate of raw material liquid to control residence time of reactants, thereby improving the yield and selectivity of the reaction; a 3D printing microchannel reactor is adopted, and a relatively complex microchannel structure can be accurately, rapidly and economically fabricated; a microchannel design using the Koch curve structure can effectively distribute gas-liquid two phases and enhance mass transfer.

Description

technical field [0001] The invention relates to a microchannel gas-liquid reactor with a Koch curve structure. Background technique [0002] CO 2 It is the most important cause of the greenhouse effect and global warming. Under the framework of the Kyoto Protocol, all countries are actively carrying out research on low-carbon green development routes. According to the annual research results and the latest research data of the Tyndall Center's "Global Carbon Project", my country has surpassed the United States to become the country with the largest carbon emissions in the world. So actively develop CO 2 Research on emission reduction is necessary. [0003] Currently, for CO 2 Emission reduction treatment methods include CCS (CO 2 capture and storage) and CCUS (CO 2 Capture, storage and utilization) and so on. [0004] in CO 2 When the total control pressure is normal pressure, the ethanolamine (MEA) aqueous solution has the characteristics of fast absorption rate, la...
