,1. Application and performance
TCOS-101 Ambient Temperature COS Hydrolysis Catalyst is mainly using our special produced macro-porous alumina oxide as catalyst carrier, it was made from loading metal active components and add kinds of other additives. It’s mainly used to hydrolyze the organic sulfide such as poisonous, harmful, corrosive COS and carbon disulfide from the coal gasification into H2S effectively. The process gas can meet the specified index requirements by matching and concatenating using TCS-306 Zinc oxide sulfur absorbent and TCS-106 desulfurizing agent.
TCOS-101 Ambient Temperature COS Hydrolysis Catalyst tandem connection to TCS-306 Zinc oxide sulfur absorbent or TCS-106 desulfurizing agent, it’s can used to hydrolysis purify COS and HS gas from the liquid phase propylene, dry process desulphurization of coal gas project for large and medium-sized city, preparation for COS gas by carbon coke as raw material, coal gas as process gas and heat source in industrial production, fine chemical, metal products processing, glass and ceramic industry, electronic products, petroleum and chemical etc industry. Such as the fine desulfurization in the production process of synthesis ammonia, methanol, combined methanol synthesis, lower carbon alcohol, synthetic fuel, town gas methanation, food grade CO2, synthesis polypropylene etc, it’s also can be used for high content of COS removal in the process of semi-water gas, water gas, coke oven gas.
TCOS-101 Ambient Temperature COS Hydrolysis Catalyst tandem connection to TCS-306 Zinc oxide sulfur absorbent or TCS-106 desulfurizing agent, with the advantage of high efficiency of hydrolysis, resistance to salinization of sulfuric acid, lower resistance of bed layer, wide applicability, convenient operation, excellent quality and favorable price etc, it’s a significant economic benefit to user and prominent social benefit.
