Gray Blue Sphere Cobalt Molybdenum Catalyst Hydrodesulfurization Catalyst
SAL-117 Cobalt-Molybdenum Hydrodesulfurization Catalyst
Description
Model:SAL-117
The Cobalt-Molybdenum Hydrodesulfurizatioin Catalyst SCST-311 is a composite catalyst with the carrier of γ-Al2O3 modified carbonization method and the active components of Co-Mo. This composite catalyst is used as the technology of catalytic cracking gasoline selective hydrodesulfurization with the low loss of gasoline octane value.
The main reactions are as follows:
RSH + H2 → RH + H2S
R1SR2 + 2H2 → R1H-R2H + H2S
C4H4S + 4H2 → C4H10 + H2S
COS + H2 → CO + H2S
CS2 + 4H2 → CH4 + 2H2S
Industrial Applications
The catalyst is suitable for removing of organic sulfur in natural gas, light hydrocarbons, etc, at ammonia plant, methanol plant, refinery plant and ammonification plant;
The catalyst is suitable for hydrodesulfurization of light petroleum.
