SCST-531 Catalyst for Crude Benzene Hydrogenation

Model：SCST-531

Catalyst for Crude Benzene Hydrogenation SCST-531 is suitable for the removal of organic sulfur by hydrogenation conversion in coking crude benzene, such as thiol, thioether, disulfide and thiophene.

The main reactions are as follows:

CS₂ + 4H₂ → CH₄ + H₂S

  C₄H₄S + 4H₂ → C₄H₁₀ + H₂S

COS + H₂ → CO + H₂S

     CH₃SCH₃ + 2H₂ → 2CH₄ + H₂S

                                                                                       C₂H₅SH + H₂ → C₂H₆ + H₂S
