The effect of H₂S contents on the transformation of 1-hexene with hydrogen over NiMoS/γ-Al₂O₃ catalyst was investigated. Inhibition of H₂S on both hydrogenation and isomerization reactions of olefin has been demonstrated. And the promotion effect of H₂S on the formation of C₆ thiols and C₁₂ thioethers has also been observed. It was found out that there was only one type of active site on the NiMoS/γ-Al₂O₃ for reactions which include hydrogenation reaction, isomerization reaction and sulfides formation reaction, and the formation reactions of sulfides were superior to both hydrogenation and isomerization reactions. The reaction network for the conversion of 1-hexene in the presence of H₂S was proposed.
