Product Profile:

HL-RR 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.
