摘要
以C4烃芳构化烷基化工艺研究为基础,对C4烃芳构化烷基化反应过程进行了热力学分析,并对反应过程的反应热进行了理论计算。热力学分析结果表明,反应温度和氢气的存在是影响该过程的两个主要因素,随反应温度的提高,液相产物收率下降,而液相产物中芳烃含量则相应增大;临氢反应条件不但增加了催化剂的活性稳定性,延长了催化剂的使用寿命,还有效降低了产物中烯烃的含量。热力学计算结果为:C4烃芳构化烷基化反应摩尔进料的反应放热量为20.094 kJ,反应过程的绝热温升为194.9℃。
Based on the investigation of the aromatization-alkylation process of C4 hydrocarbons, the thermodynamic analysis of the process was carried out and reaction heat of the process was obtained by theoretical calculation as well as simulation with Aspen Plus software. The results showed that reaction temperature and the presence of hydrogen were the main factors affected the process. With the increase of reaction temperature, the yield of liquid product decreased whereas the aromatic content in the liquid product increased. Due to the presence of hydrogen the catalyst stability was improved and its service life was prolonged, furthermore, the olefin content of the product was significantly reduced. A reaction heat of 20. 094 kJ per mol C4 hydrocarbons feed and an adiabatic temperature increase of 194. 9 ℃ was obtained by thermodynamic calculation.
