Abstract: 1,4-butanediol(BDO),hydrogenation product of 1,4-butynediol(BYD),is an important organic chemical raw material. The main problems of industrial hydrogenation of BYD are high pressure,huge capital investment and catalyst deactivation. Characteristics of the hydrogenation process of BYD,characteristics and confronting problems of hydrogenation process,development of Ni-based,Pt-based and Pd-based catalysts for hydrogenation process and new types of reactors were reviewed. Based on the characteristics of great impact of hydrogen concentration of catalyst surface on the BYD hydrogenation reaction process,it was proposed to improve the hydrogenation process of BYD by enhancing the gas-liquid,liquid-solid mass transfer efficiency and to reduce the hydrogenation pressure. The activity and stability of the catalyst could be improved by adding supporting metals and change of the carriers. The development trends of low pressure 1,4-butynediol hydrogenation catalyst and reactor were discussed. Combining the magnetic properties of the Ni-based catalyst used in the hydrogenation process,the potential application of magnetically assisted fluidized bed reactor in BYD hydrogenation process was proposed.

Key words: 1,4-butynediol, 1,4-butanediol, hydrogenation, process intensification, catalyst, reactors

摘要: 1,4-丁炔二醇(BYD)加氢产物1,4-丁二醇(BDO)是重要的有机化工原料,工业上该加氢过程存在反应压力高、设备投资大、催化剂易失活等问题。本文综述了1,4-丁炔二醇加氢反应过程的特点,对比了不同BYD加氢工艺并分析了各工艺特点和面临的问题,回顾了Ni基、Pt基、Pd基加氢催化剂的开发进展,简述了新型加氢反应器的特点与研究进展。基于催化剂表面氢浓度对BYD加氢反应过程影响显著的特点,提出通过强化反应过程气液、液固传质效率对BYD加氢过程进行改进,以期降低反应压力。通过加入金属助剂和改变载体性质开发加氢催化剂,提高催化剂活性和稳定性。最后总结展望了开发BYD低压加氢剂催化剂和低压加氢反应器的发展趋势,结合BYD加氢Ni基催化剂具有磁性的特点,提出磁场辅助流化床对BYD加氢过程的潜在应用前景。
