SCST-311 Cobalt-Molybdenum Hydrodesulfurization Catalyst

Model：SCST-311

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】
