A918 catalyst for sulfur recovery
A918 catalyst of sulfur recovery is a artificial synthesizing active Al2O3 catalyst, which possess stronger performance of anti-sulfated poison, higher hydrolysis function of organic sulfur compounds and better character of heat steady. The effect of industrial trial has proved that A918 catalyst have the advantages of high activity and crush strength ,which can be used for 3 years continuously .Compared to the bauxite ,the total yield of sulfur recovery can be increased from 80~85% to 94~96% in equal or similar process conditions. The hydrolysis of COS has reached 100% and the sulfur amount of tail gas has decreased below to 1%. All kinds of properties of A918 catalyst, whose specific surface area attained 320m2/g, have reached the advanced level in the world.
