Product Introduction
A918 activated alumina catalyst of sulfur recovery is an 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 activated alumina catalyst have the advantages of high activity and crush strength, which can be used for 3~5 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 activated alumina catalyst, whose specific surface area attained 320m2/g, have reached the advanced level in the world.

Application
The Claus process is used by the sulfur recovery Industry which converts hydrogen sulfide into elemental sulfur and water. The "sour" natural gases have plenty of hydrogen sulfide within and if such gases are burned as fuel, sulfide escapes, resulting in air pollution and damage to our tender environment. It has become an inevitable demand of mankind to convert maximum quantity of sulfur from "sour" gas.
Al2O3 activated alumina catalyst is the most widely used as Claus catalyst which contains a large number of catalytic active surface sites that absorbs Hydrogen Sulfide (H2S) and Sulfur Dioxide (SO2) for subsequent reaction to yield elemental sulfur.
In many acid gas streams, sulfur is present in various compounds such as H2S, COS, CS2, etc. Some of them may not be present in the feed gas but cumbustion of H2S in the presence of CO2 or hydrocarbons could result the formation of COS/CS2. These compounds must be converted to ensure proper sulfur conversion. Since the decomposition rate of these compounds are at lower rate than that of H2S/SO2 reaction, a highly active catalyst is required. Sulfation can be another problem as it reduces surface area and hence, the deactivation of catalyst.
Our high performance Sulfur Recovery Activated Alumina Catalyst are ideal for Claus units in natural gas plants, oil refineries, coke plants, tail gas units, etc.
