用苯及环已烷分别在高温高氢压下评价了常用破坏加氢催化剂的活性。根据所得结果可按其活性的高低排成如下的次序。氢化活性:WS_2-NiS-Al_2O_3≥Pt-F-Al_2O_3>WS_2>MoS_2>MoS_2-活性碳>CoMoO_4-Al_2O_3>WS_2-Terrana;异构化活性:WS_2-Terrana>WS_2>MoS_2>Pt-F-Al_2O_3>WS_2-NiS-AL_2O_3>CoMoO_4-Al_2O_3>MoS_2-活性碳;裂化活性:WS_2-Terrana>Pt-F-Al_2O_3≥WS_2>MoS_2>WS_2-NiS-Al_2O_3>CoMoO_4-Al_2O_3>MoS_2-活性碳。从这些性能的比较中,讨论了关於载体对有效成分的氢化,异构化及裂化活性的影响,以及苯的氢化与异构化反应之间之相互关系,即同时并考察了具有高选择性的MOS_2-活性碳催化剂在高温高压下对苯核的氢化作用,确定了其最适氢化条件以供环已烷生产之用。
The activity of the common destruction hydrogenation catalyst was evaluated at high temperature and high hydrogen pressure respectively with benzene and cyclohexane. Based on the results obtained according to the level of their activity ranked in the following order. Hydrogenation Activity: WS_2-NiS-Al_2O_3≥Pt-F-Al_2O_3> WS_2> MoS_2> MoS_2-Activated Carbon> CoMoO_4-Al_2O_3> WS_2-Terrana; Isomerization activity: WS_2-Terrana> WS_2> MoS_2> Pt-F-Al_2O_3 > WS_2-NiS-AL_2O_3> CoMoO_4-Al_2O_3> MoS_2-activated carbon; cracking activity: WS_2-Terrana> Pt-F-Al_2O_3≥WS_2> MoS_2> WS_2-NiS-Al_2O_3> CoMoO_4-Al_2O_3> MoS_2-activated carbon. From the comparison of these properties, the influence of the carrier on the hydrogenation, isomerization and cracking activity of active ingredients and the relationship between the hydrogenation and the isomerization reaction of benzene are discussed, that is, the high selectivity Of the MOS_2-activated carbon catalyst under high temperature and high pressure benzene nucleus hydrogenation, to determine the optimum hydrogenation conditions for the production of cyclohexane.
