Abstract

The invention relates to a preparation method and application of a novel graphene foam rectifying tower filler. At a high temperature, through a solvothermal way, a graphene oxide solution is subjected to molding; a metal frame structure is embedded in a process; thus, one rectifying tower filler unit is formed; a porous structure of the rectifying tower filler unit can be used as a microreactor for catalytic rectification. A novel three-dimensional graphene filler is compared with HY-Pac and Pall ring fillers, and is used for filling a rectifying tower; a graphene filler maintains a regular filler property to a great extent; the mass transfer capacity is high; the graphene filler is large in liquid holdup, and can be used as a novel catalytic microreactor; the pressure drop of the graphene filler can be decreased to 1/3 of that of a conventional filler.

Description

technical field [0001] The invention belongs to the technical field of chemical separation, and in particular relates to a preparation method and application of a novel graphene foam rectifying tower packing. Background technique [0002] The chemical industry is a pillar industry of the national economy, and separation technology provides technical guarantees for raw material purification, product purification and waste treatment in the chemical production process. With the development of chemical engineering technology, separation technology is gradually developing towards diversification. Conventional chemical separation technologies include rectification, absorption, extraction, crystallization, adsorption, membrane separation, etc. Rectification is still one of the most widely used and mature separation methods, and occupies a considerable proportion in industrial production. [0003] Distillation is the most widely used key common technology in the chemical industry,...
