摘要
本文利用正交配点法计算了蛋壳型催化剂的等温有效因子。文中通过坐标变换将非零一区间的两点边值问题转化为[0,1],区间的两点边值问题,使计算过程比 G 法简便,且计算精度亦优于 G 法。
The governing equations of reaction and diffusion in the active outer crust of spherical catalysts with inert inner core was transformed into bounary value problem over the interval [0,1] by coordinate transformation and mathematical manipulation.The orthogonal collocation method was used to calculate the isothermal effectiveness factors of catalysts.The calculation procedure was simpler than those of Goyal method and other numerical -intergral methods.The results showed good agreement with those from nu- merical-intergral method and higher accuracy than those from Goyal method.
