COS Hydrolysis Catalyst in Chemical Industry

COS is the main organosulfur component in the treatment of chemical raw material gases, such as conversion gas, synthesis gas, water gas and liquefied gas. The use of organic sulfur hydrolysis catalysts can hydrolyze trace amounts of COS, CS2 and other organic sulfides in the raw gas to produce H2S, which is easy to remove, thus realizing the recovery of sulfur. These catalysts are typically operated at temperatures between 150 and 250°C, and have a high organic sulfur conversion rate, greater than 95.0%.

COS Hydrolysis Catalyst Characteristics

● Accelerated reaction: The catalyst can significantly increase the rate of reaction of organosulfur compounds with water.

● Selectivity: The catalyst can improve the selectivity of the reaction and reduce the generation of by-products.

● Environmentally Friendly: Organic Sulfur Hydrolysis catalysts are generally more environmentally compatible than conventional catalysts, reducing the impact on the environment.

● Efficient: Highly efficient hydrolysis reactions can be achieved at lower temperatures, helping to reduce energy consumption and production costs.

Main applications of COS Hydrolysis Catalyst

● Chemical raw material gas treatment: COS is the main organosulfur component in chemical raw material gases (e.g., reformate gas, synthesis gas, water gas, liquefied gas). Organic sulfur hydrolysis catalyst can hydrolyze the trace COS, CS2 and other organic sulfides in these raw gases to generate H2S, which is easy to remove, thus realizing the recovery of sulfur and the purification of raw gas.

● Pesticide synthesis: In pesticide synthesis, organosulfur hydrolysis catalysts are widely used to increase the reaction rate, reduce the generation of by-products, and improve the selectivity and yield of the reaction. At the same time, these catalysts have less impact on the environment and produce less waste in the process, which helps to avoid environmental pollution.

● Pharmaceutical production: COS Hydrolysis Catalyst in the pharmaceutical field can promote certain chemical reactions, improve the synthesis efficiency and product purity.

In addition to the above applications, COS Hydrolysis Catalyst are also used in the manufacture of flavors and fragrances, the esterification of alcohols and acids, the hydrolysis of organosulfur at ambient temperature, and the purification of industrial gases.
