苯加氢制环己烷工艺及催化剂研究进展

Advance in processes and catalysts for benzene hydrogenation to cyclohexane

介绍了苯加氢制环己烷工艺及催化剂研究现状,对比各工艺和催化剂的优缺点,气相法和液相法是苯加氢制环己烷的成熟工艺,在未来很长一段时间仍将是苯加氢制备环己烷的主要工艺。开发高活性、耐热性能好和抗毒能力强的贵金属催化剂是苯加氢制备环己烷催化剂的研究方向。

The research status of the processes and the catalysts for benzene hydrogenation to cyclohexane was reviewed. The advantages and disadvantages of the processes and the catalysts were compared. The vapor phase and liquid phase processes for benzene hydrogenation were mature and also main technology for a long time in the future. The research direction of benzene hydrogenation to cyclohexane was the development of noble metal catalysts which possessed high catalytic activity, good resistance to heat and poisoning.
