摘　　要：研究了反应物进料速度、催化剂用量和反应温度对以非晶态合金雷尼镍为催化剂的液膜多相反应模式下异丙醇脱氢反应的影响,考察了反应动力学.结果表明,温度的影响最显著,与搅拌釜液相脱氢相比,该反应模式有效提升了产氢速率,Langmuir-Hinshelwood反应动力学表达式计算结果与实验结果吻合良好.Effects of the feed rate, the amount of catalyst and the reaction temperature on the multiphase dehydrogenation reaction of isopropanol in a liquid film reactor with the amorphous alloy Raney nickel as catalyst were studied. The reaction kinetics was researched. The results showed that the effect of temperature was the most significant factor. Compared with the liquid phase dehydrogenation of the stirred tank, this reaction mode effectively improved the hydrogen production rate. The kinetic expression of Langmuir-Hinshelwood was obtained which agreed well with the experimental results.
