Product Introduction
Claus sulfur recovery catalyst is a white spherical particle, insoluble in water and organic solvents, soluble in strong acid and strong alkali solutions, hygroscopic in the air, and does not swell or crack after absorbing water. It has the characteristics of high strength, strong resistance to sulfation poisoning and good thermal stability.
The sulfur recovery catalyst produced by Zibo Xiangrun is a catalyst used for petrochemical and other industrial treatment of acidic gases that are converted into sulfur for recovery through liquefaction; the catalyst used in Claus sulfur recovery unit has high conversion rate, long service life and good exhaust gas desulfurization effect. It is also suitable for Claus sulfur recovery process in refineries containing H2S acid gas, natural gas purification and desulfurization plants, city gas plants, petrochemical plants and chemical plants.

The role of Claus sulfur recovery catalyst
The main function of Claus catalyst is to accelerate the conversion reaction of H₂S and SO₂ and ensure the efficient generation of sulfur. The ideal catalyst should have the following characteristics:
High catalytic activity: increase the reaction rate and reduce by-products.
Good thermal stability: adapt to the high temperature environment of Claus reaction.
Anti-poisoning ability: resist the influence of impurities such as water vapor, hydrocarbons, and organic sulfur compounds.
High mechanical strength: avoid catalyst breakage due to airflow impact or temperature changes.
Applications of Claus sulfur recovery catalysts
· Natural gas desulfurization plants: treatment of acidic gases containing H₂S.
· Refineries: recovery of sulfur produced during oil processing.
· Coal chemical industry: purification of sulfides in coal gasification or coke oven gas.
· Environmental engineering: reduction of sulfur emissions in industrial waste gas to meet environmental regulations.
Claus catalyst is the core of Claus process. By optimizing the selection and use of catalyst, the sulfur recovery rate can be significantly improved (up to more than 99%) while reducing environmental pollution. It plays an irreplaceable role in the energy and chemical industries.
