摘    要:以Raney镍为催化剂,在淤浆鼓泡床中进行丁炔二醇加氢合成丁二醇这一两步串联加氢反应。探讨了在实验条件下气液传质、液-固传质和颗粒表面反应的相对阻力,从而用定量对比法确证反应属动力学控制。其本征速率方程可用幂函数或Langmuir-Hinshelwood模型表达。前者适用于宏观过程对比;后者适用于本征机理研究,并可对液相反应物级数的变化作出满意的解释。

关 键 词:加氢反应  金属催化剂  动力学分析  淤浆鼓泡床  Raney镍催化剂  过程动力学  丁炔二醇  丁烯二醇  丁二醉

Abstract:With Raney nickel as catalyst, the two steps hydrogenation reaction of 1,4-butynediol to 1, 4-butanediol carries out in bubbling slurry bed. The relative resistances of gas-liquid masstransfer, liquid-solid mass transfer and pellet surface reaction are determined under experimental conditions, thus the surface reaction rate controlling can be predicted by this quantitative method.Both intrinsic rate equations of two steps can be expressed as power model or/and Langmuir-Hinshelwood model. The former is more favorable for correlation with transport process, while the latter benefits for reaction mechanism studies, and also the variations of reaction order of both liquid reactants have been explained rather successfully.
Keywords:hydrogenation reaction  metal catalyst  kinetics analysis  bubbling slurry bed  Raney nickel catalyst  process kinetics  1  4-butynediol  1  4-butenediol  1  4-butanediol
