摘要
通过坐标变换和数学推导将蛋黄型催化剂活性区内的反应—扩散方程转化为[0.1]区间的两点边值问题,利用正交配点法计算了蛋黄型催化剂的等温有效因子。所得结果与数值积分法的结果极其接近,计算工作量显著小于数值积分法的计算工作量。
Equation of reaction and diffusion in the active inner core of spherical catalysts with
inert outer crust was transferred into boundary-value problem over (0, 1) domain by
the coordinate transfer and the mathematical derivation. The orthogonal collocation
method was used to calculate the isothermal effectiveness factors of the catalysts. The
results were in good agreement with the numerical-integral solutions. The computative
time of orthogonal collocation method was less than that of the numerical-integral
method.
