SCST-301 iron-manganese desulfurizing catalyst

Model：SCST-301

The Iron-manganese Desulfurizing Catalyst SCST-301 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

CH3_SCH₃ H₂S + C₂H₄

H₂S with metal

     H₂S + MO → MS + H₂O  (M is the abbr of metal)

【Industrial Applications】
