The GJS-81 catalyst has a large pore volume and a large pore size due to the use of a special large-pore alumina carrier. The catalyst has the following characteristics: ○ Strong metal containing capacity, high rate of demetallization (vanadium, nickel and other metals) ○ Carbon containing capacity Strong, high residual carbon removal rate ○ Slow down catalyst deactivation, long service life
