what is Sulfur recovery catalyst?

Sulfur recovery catalyst in the process of coal, oil and gas processing to produce large amounts of H2S gas, in order to protect the environment and the recovery of elemental sulfur, the claus process widely used industrial, acidic gas H2S are dealt with. Industrial application shows that, under the high temperature furnace can achieve general furnace H 2 s conversion rate can reach 65% 75%, if the secondary Klaus craft, the total sulfur conversion is about 92-95%

In recent years, mainly about the role of sulfur recovery catalyst at home and abroad are:

(1)

Dutch Comprimo company of hydrogen sulfide selective oxidation catalysts developed in the eighty s, mainly divided into two Al2O3 and SiO2, together with the total sulfur recovery rate can reach 99.5%.

(2)

The French Rhone - Poulenc company developed a new generation of Al2O3 catalyst CR - 3 s, its are main the feature is > 0.1 u hole entrance is more than 12 ml / 100 g catalyst, greater than 1 u entrance of the hole of more than 7.8 ml / 100 g catalyst, that is greater than 1000 entrance of the hole of ao accounted for most.

(3)

Kaiser aluminum and chemical companies in the United States have developed the S - 2001 al2o3 catalyst, its main characteristic is greater than 500 ao hole of the majority.

(4)

French patent EP692306 a Al2O3 catalyst is introduced, its main characteristic is Na2O content in the catalyst is less than 2400 PPM, sulfate resistance is strong, high organic sulfur hydrolysis rate.

(5)

French Rhone - poulenc company developed a zirconium oxide catalysts, cerium oxide and/or TiO2 as active components, and is characterized by good low temperature activity, sulfate resistance ability.

(6)

France Elf - Aquitaine, company developed by SiC as the carrier of catalyst, its main characteristic is not going to happen the sulfuric acid salinization, high activity and stability.
