Fe-Mn Bifunctional Desulfurizer
SCST-301 Fe-Mn bifunctional desulfurizer is a conversion absorption desulfurizer with Fe2O3 and MnO2 as the main components and containing ZnO accelerators, which is widely used in the fine removal of organic sulfur and inorganic sulfur in natural gas, coke oven gas, refinery gas, water gas and other devices. Under the action of the desulfurizer, organic sulfur such as RSH, RSR, COS, CS2 is decomposed into H2S by hydrogen pyrolysis, and then reacts with the active metal oxides in the desulfurizer to produce metal sulfide, so as to achieve the purpose of removal.

Technical Features
Resistant to high pressure and high space velocity, having a longer service life under a high pressure and high space velocity operation than domestic similar catalysts.
Large specific surface area, high conversion rate and high selectivity, having certain conversion ability to thiophene and other complex organic sulfurs.
Excellent in activity, mechanical strength and structural stability.
Natural gas to hydrogen technology
After pre-treatment, natural gas or other light hydrocarbon raw materials are mixed with steam and enter a special conversion furnace. Under the action of nickel catalyst SCST-20X, steam reforming reaction occurs to generate conversion gas containing H2, CO2, CO and other components. After recovering heat from the conversion gas, the conversion gas containing CO2 and H2 is obtained through water vapor shift reaction, and then purified by PSA to obtain high-purity H2. The PSA tail gas is returned to the conversion furnace for combustion and heat recovery.
Conventional Methanol-to-Hydrogen Technology
1. Methanol-to-hydrogen technology has certain advantages among various hydrogen production technologies due to its wide availability of raw materials, technological maturity, ease of operation, economic efficiency, and environmental friendliness.
2. Process Flow: Methanol and steam, under specific pressure and temperature conditions, pass through a methanol-steam reforming catalyst bed to generate reformed gas, whose main products are carbon dioxide and hydrogen. This reformed gas is then subjected to pressure swing adsorption to obtain product hydrogen with a purity of 99.0%~99.999%.
