Iron Manganese Desulfurization Desulphurization Catalyst
SAL-115 Iron-manganese desulfurizing catalyst
Description
Model:SAL-115
The Iron-manganese Desulfurizing Catalyst SAL-115 is developed and manufactured by us with the latest scientific and technological breakthroughs. The catalyst owns double-effect function of organic sulfur hydrogenation and desulfurization. By using the catalyst, organic sulfur is converted into inorganic sulfur(H2S) by hydrogenolysis, hydrolysis and pyrolysis processes, and then, H2S and active metal oxide react to become metal sulfide, which is absorbed by the catalyst to achieve the sulfur removal purpose, the catalyst can be regenerated.
The main reactions are as follows:
Hydrogenolysis
RSH + H2 → H2S + RH
RSR + H2 → H2S + RH + RH
RSSR + 3H2 → 2H2S + RH + RH
Hydrolysis
RSH + H2O → H2S + ROH
RSR + H2O → H2S + 2ROH
Pyrolysis
2CH3SH 2H2S + C2H4
CH3SCH3 H2S + C2H4
H2S with metal
H2S + MO → MS + H2O (M is the abbr of metal)
Industrial Applications
The catalyst is suitable for sulfur purification system of natural gas, coke oven gas, oil field gas, naphtha, refinery and dry gas.
