SCST-313 Nickel-Mo desulfur catalyst

Model：SCST-313

The Nickel-Molybdenum Hydro-desulfurization Catalyst SCST-313 takes sphere shaped aluminum oxide as carrier and Ni-Mo as its main activity components. It’s usually used for gas / oil desulfurization of ammonia plant or hydrogen generation from refinery, hydrotreating conversion and removal of organic sulfur from coke oven gas. Meanwhile, it hydro treats and saturates olefin in the gas.

The main reactions are as follows:

COS + H₂ → CO + H₂S     CS₂ + 4H₂ → CH₄ + 2H₂

C₂H₅SH + H₂ → C₂H₆ + H2S     CH₃SCH₃ + 2H₂ → 2CH₄ + H₂S

C₄H₄S + 4H₂ → C₄H₁₀ + H₂S     C_nH_2n + H₂ → CnH_2n+2

【Industrial Applications】

• The catalyst is suitable for sulfur purification system of natural gas, coke oven gas, oil field gas, naphtha, refinery and dry gas;
• The catalyst is suitable for producing natural gas from coke oven gas.
