摘要：以工业生产的实际数据对实验关联的噻吩加氢脱硫表观反应动力学方程加以修正,得出反应动力学方程:r=6.935×1-0 12exp-45 054RTp1.H 42p0.T h83。研究了等温条件下温度对噻吩加氢的影响,并对二段反应器中实际温度的测定曲线进行了模拟比较。结果表明:温度是噻吩脱除反应的关键因素,入口温度应随着床层绝热温升的下降而逐步提高。
Industrial operation data based on correction of the apparent kinetics of thiophene desulfurization derived from laboratory study was considered to be more reliable, and was expressed as follows. r=6.935×10^-12exp（-45054/RT）PH2^1.4PTh^0.833. The influence of temperature on hydrogenation of thiophene under isothermal condition was simulated, and a simulation was then made for the second stage reactor from actual temperature profiles in the catalyst bed. The results show that temperature is the critical factor for thiophene removal, and the inlet temperature should be raised corresponding to the decrease of adiabatic temperature rise occurred in the bed.
