Abstract

The invention provides a microchannel plate with a fractal structure, a photocatalytic reactor and an application thereof. The microchannel plate with the fractal structure comprises a first surface and a second surface which are opposite; the first surface and the second surface of the microchannel plate with the fractal structure each is provided with a main pipeline microchannel and multistage H-shaped fractal bifurcated microchannels which are connected with one end of the corresponding main pipeline microchannel, and the H-shaped fractal bifurcated microchannels of the first surface of the microchannel plate with the fractal structure communicate with those of the second surface of the microchannel plate with the fractal structure through connecting through holes. According to the microchannel plate with the fractal structure, the photocatalytic reactor and the application thereof, through forming fractal-structured microchannels in the upper and lower surfaces of the microchannel plate with the fractal structure, three phases, i.e., gas, liquid and solid phases can be effectively distributed, heat transfer and mass transfer are strengthened, the problem in collection of reactants of fractal distribution can be effectively solved, meanwhile, the length of the microchannels can be increased, and the control on reaction flux and reactant residence time is better facilitated.

Description

technical field [0001] The invention belongs to the field of chemical engineering photocatalysis, and in particular relates to a microchannel plate with a fractal structure, a photocatalytic reactor and applications thereof. 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 Emission reduction and CO 2 Research on transformation and utilization 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), etc. However, in ...
