Composition Metallic Oxide Desulfurizing Agent
HT-702 fine desulfurizing agent is a new-type, high efficient and non-oxygen resistance fine desulfurizing agent. It can be used in oxygen-free conditions with temperature from 0 to 60℃. Combined with using COS hydrolytic catalyst, it can remove H2S and COS to meet the requirements on sulfide content. It can purify H2S without O2 in various kinds of gas and liquid materials such as natural gas, syngas, oil field gas, ammonia refining, crude oil and naphtha.
Advantages
Large working sulfur capacity,
Be applied in anaerobic and liquid-phase conditions,
Be aoolied in high concentrations of CO2,
High strength and good water resistance.
Application
The desulfurizer is suitable for the removal of H2S in liquid hydrocarbons such as liquefied gas, light hydrocarbons, naphtha, solvent oil, gasoline, and diesel. It can solve the corrosion of liquid hydrocarbon copper sheets.
It is also suitable for the fine removal of H2S in natural gas, (semi-)water gas, air gas, coke oven gas, shift gas, C02 regenerative gas, food C02, synthetic raw gas, biogas, waste gas and other famous gases, with a wide range of applications.
Reaction principle
The main active components of HT-702 composite oxide refined desulfurizer are iron oxide, zinc oxide, etc. The reaction formula is:
Fe203·H2O+3H2S=Fe2S3·H2O +3H20 Zn0+H2S=ZnS+ H20
