摘要:
该文对丁醛加氢反应循环反应液质量与新进醛质量比(循环比)、丁醛质量浓度对应的转化率和反应速率的关系、2级加氢反应转化率、尾气组成分析、丁醛液相杂质影响、水形成原因进行了实验研究.实验结果表明:反应温度、丁醛入口质量浓度是影响加氢反应速率的重要因素; 在160 ℃、2级反应条件下,丁醛总转化率可达99.60%; 在体系中的水会影响催化剂的稳定性,当在体系中水的质量分数达到5.00%以上时,催化剂会出现粉化现象,2聚和3聚副产物对在体系中水的含量有明显的影响.
Abstract:
In this paper,two different catalysts are used to produce butanol by butyraldehyde liquid hydrogenation. And the relationship between the mass of the reaction solution/the mass of the new aldehyde(cycle ratio)of the butyraldehyde hydrogenation cycle, the conversion rate and reaction rate corresponding to different concentrations,the conversion rate of the two-stage hydrogenation reaction,the analysis of tail gas composition,the influence of butyraldehyde liquid phase impurities,and the causes of water formation are experimentally studied.The experimental results show that the reaction temperature and butyraldehyde inlet concentration are important factors affecting the hydrogenation reaction rate.Under the condition of 160 ℃,the total conversion rate of butyraldehyde can reach 99.6%.The water in the system affects the stability of the catalyst, and when the content is 5% or more, the catalyst is pulverized, and the dimer and trimer by-products have a significant effect on the water content in the system.
