Desulphurization Catalyst
Desulphurization Catalyst Introduction
Desulphurization Catalyst IntroductionZinc oxide desulfurizer plays a very important position because of its high desulfurization precision, easy to use, safe and reliability, high sulfur capacity, and plays the role of “gateway” and “protection” . Based on the traditional preparation process of zinc oxide desulfurizer, our company has improved and developed HT-305 wide temperature zinc oxide desulfurizer, which can be used in coal chemical industry, hydrogen production, petroleum refining, beverage production and other industries to remove coke oven gas, natural gas, synthetic gas, petroleum fractions, oilfield gas, refinery gas, carbon dioxide and other raw material gases such as hydrogen sulfide and certain organic sulfur, and remove the sulfur in the raw material gas (oil) to below 0.05ppm, thus ensuring the follow-up Nickel, copper, iron and precious metal catalysts in the process of methanol, methanation, low shift, steam reforming, low carbon alcohol, carbonyl synthesis, etc. are free from sulfur poisoning.
Desulphurization Catalyst principle and properties
1) Reaction principle
ZnO+H2S=ZnS+H2O ZnO+COS=ZnS+CO2
ZnO+C2H5SH=ZnS+C2H4+H2O 2ZnO+CS2=2ZnS+CO2
