摘要：采用固定床反应器对四氢萘在Ni Mo/HY工业催化剂上的加氢裂化反应过程进行了研究,考察了反应温度对产物分布的影响,提出了四氢萘加氢裂化反应网络。该网络包含加氢、异构、脱氢、开环、脱烷基等12个反应,通过热力学计算,得到了这些反应的平衡常数,并据此求得各类产物的平衡收率及其随温度、压力和氢气/四氢萘(摩尔比)的变化规律。由热力学平衡分析得到的产物收率随反应条件的变化规律与实验结果较为吻合,表明本文构建的反应网络可以较好地描述Ni Mo/HY催化剂上的四氢萘加氢裂化反应体系。
Tetralin hydrocracking over a commercial catalyst Ni Mo/HY was carried out to study temperature effect on product distribution in a laboratory-scale fixed-bed reactor. Based on the experimental results, a reaction network for tetralin hydrocracking was proposed, which contained 12 reactions with different types such as hydrogenation, isomerization, dehydrogenation, ring opening and dealkylation. Thermodynamic equilibrium calculations provided equilibrium constants for all reactions in the network, equilibrium yields of different products as well as yield variations with temperature, pressure and molar ratio of H2 to tetralin. Thermodynamic calculation of product yield changes with operating conditions was generally in agreement with those of experiments, demonstrating that the reaction network depicted well for tetralin hydrocracking over Ni Mo/HY catalyst system.
