摘要：在固定床反应器中,采用Cu-SiO_2催化剂,在温度160~200℃、压力2MPa^5MPa,氢酯物质的量比100~300和DMM空速0.2~0.5h^(-1)的反应条件下对DMM加氢制1,3-PDO进行了研究。结果表明,在低温、高压、高氢酯比的条件下有利于DMM的转化率和1,3-丙二醇选择性的提高。较适合的反应条件为:压力5MPa,温度180~190℃,氢酯比300,DMM空速0.4h^(-1)。动力学研究表明,DMM加氢反应符合L-H吸附反应动力学模型。表面反应为速率控制步骤,氢气不解离吸附,由此得到了相应的动力学方程及参数。统计检验结果表明,该模型对DMM加氢反应高度适定。
Hydrogenation of dimethyl malonate（DMM） to 1,3-proanediol（13,-PDO） over the Cu-SiO2 catalyst in the fixed-bed reactor was studied. Effects of temperature, pressure, feed mole ratio of H2 to DMM, and space velocity on the reaction were investigated in the ranges of 160-200℃, 2-5MPa, 100-300 and 0.2-0.5h^-1, respectively. Both of DMM conversion and 1,3-PDO selectivity could be improved at lower temperature and higher pressure and mole ratio of H2 to DMM. The optimal reaction conditions were determined as follows： 5MPa, 180-190℃, H2/DMM mole ratio of 300 and DMM space velocity of 0.4h^-1. It was found that L-H type mechanism model could properly predict the behavior of reaction system, and the rate-determining step was the surface reaction.Simulation results in fixed-bed reactor well reflected the influence of each operational parameter and accorded with experimental results, so this model was highly suitable for DMM hydrogenation reaction.
