Abstract

The invention discloses a catalyst with high superficial area for liquid solid reaction. The catalyst is a spherical structure, and three groups of circular holes are arranged on the spherical catalyst; every group of circular hole comprises two circular holes, and the axial leads of two circular holes are overlapped and crossed through the center of sphere; the axial lines of three groups of circular holes are perpendicular to each other; continuously spiral grooves are arranged on the inner walls of the circular holes. A multiphase catalyst has relatively high superficial area and strong mechanical strength at the same time.

Description

technical field [0001] The invention relates to a catalyst, in particular to a catalyst for liquid-solid reaction with a high surface area. Background technique [0002] Catalyst molding is a unit operation process in which various powders, granules, solutions or melt materials are aggregated under a certain pressure to form solid catalyst particles with a certain shape, size and strength. It is an indispensable process in catalyst production. , has a certain influence on the mechanical strength and performance of the catalyst. Catalysts can be molded and processed to provide granular catalysts with suitable shape, size and mechanical strength according to the catalytic reaction and device requirements, and make the catalyst fully exert its activity and selectivity, which is also beneficial to prolong the service life of the catalyst. Reduce the pressure drop generated by fluid flow, prevent channeling and obtain uniform fluid flow. Since the liquid-solid heterogeneous cat...
