根据幂指函数g(u)=ua+bu的特点,借用“虚拟反应组分”和“变动级数”的概念,提出了管式反应器系统中反应转化率与工艺条件的关系式XM=1-exp[-exp(A+B/Tr+CTr)Prnpo+np1prτr multiply from i=1 to m yinyo+ny1yi]为了验证该转化率方程的普适性,考察了二乙苯催化脱氢、乙苯加氢和噻吩加氢脱硫等,并利用Matlab软件分别对这三个催化体系的实验数据进行拟合.结果表明,此方程在较宽的范围内均能很好地反映温度、反应压力、空速和物料比对转化率的影响.预测结果与实验数据之间的总平均相对偏差均小于2%,说明该方程并不是针对某一特定的催化反应或催化剂,可用于大多数的管式反应器催化反应系统中.
According to the concept of exponential function g (u) = ua + bu, the concepts of reaction rate and process conditions in tubular reactor system are proposed by using the concepts of “virtual reaction component” and “change order” In order to verify the universality of the conversion rate equation, the effect of diethylbenzene catalysis was investigated. XM = 1-exp [-exp (A + B / Tr + CTr) Prnpo + np1prτr multiply from i = 1 to m yinyo + ny1yi] Dehydrogenation, ethylbenzene hydrogenation and thiophene hydrodesulfurization etc. The experimental data of these three catalytic systems were respectively fitted by Matlab software.The results show that this equation can well reflect the temperature in a wide range , Reaction pressure, space velocity and material ratio on the conversion rate.The total average relative deviation between the predicted and experimental data is less than 2%, indicating that the equation is not for a specific catalytic reaction or catalyst can be used for large Most tubular reactor catalytic reaction system.
