Abstract

The invention provides a microchannel plate based on a cross-shaped curve, a gas-liquid reactor and reaction system and application. The microchannel plate based on the cross-shaped curve comprises areaction plate, a cross-shaped fractal structure microchannel, an input microchannel and an output microchannel, wherein the cross-shaped fractal structure microchannel, the input microchannel and theoutput microchannel are formed on one surface of the reaction plate; the input microchannel and the output microchannel are respectively connected to the two ends of the cross-shaped fractal structure microchannel to form a through reaction channel. A microfluidic technology and a continuous reactor are combined in order to effectively and rapidly control the flow of a feed solution, thereby controlling the retention time of reactants and improving the reaction yield and selectivity; the fractal structure microchannel is designed for effectively distributing gas and liquid phases, so that mass transfer is enhanced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of chemical engineering catalysis, in particular to a microchannel plate based on a cross curve, a gas-liquid reactor, a reaction system and its application. Background technique [0002] In the field of energy and chemical industry, low-carbon olefins are a very important class of high-value-added basic chemical raw materials. Many products such as synthetic fibers, synthetic rubber, synthetic plastics, high-grade lubricants, high-carbon alcohols, and jet fuels use them as basic raw materials. Olefins The development level of the industry and the balance between supply and demand in the market directly affect the development level and industrial scale of the entire chemical industry. [0003] Among the gas-liquid reactions that use olefins as reaction substrates and can use homogeneous catalysts, the hydroformylation reaction is the most representative, and the aldehydes generated by the hydroformylation reaction can...
