Raschig Alumina Catalyst Support
Description
Technical Parameters
Hollow cyclinder alumina catalyst support crystal form:
θ-Al2O3 or α- Al2O3.This product is white hollow cylindrical particles, non-toxic, odorless, insoluble in water and ethanol.HL-RRB product is used as catalyst covering support and adsorbent material in the reactor. Its main function is to increase gas or liquid distribution point and support and protect active catalyst with low strength. It has the characteristics of high purity, good heat resistance, mechanical impact resistance and stable chemical performance, and is widely used in petrochemical, natural gas, coal chemical and other industries.
