计算机辅助模拟计算催化剂颗粒内的一级等温平行反应——忽略外扩散的影响

Simulating and calculating the forst-order Isothermal Parallel Reactions With in a Porous Catalyst particle by Computer——Neglecting the External Diffusion

本文是采用正交配点法和高斯一约当消无法 ,用计算机语言 ,在忽略外扩散条件下 ,对催化剂颗粒内进行的一级等温平行反应的产物和反庆物浓度的变化情况进行模拟计算 ,并把数值解和解析解进行了对比分析 ,取得了比较满意的结果。

In present work, the Corthogonal collocation and Gallss-Jodar method have been adopting. In the condition of neglecting the external diffusion, the darge of concentration has been given for the prodncts and reactant of the first-order isothermal parallel reactions in the porous catalyst partide by computer. For the more, the Numerical and ANlytic solutions have been aralysed and compared, and the results are satis factory. Key Word:Orthogond Collocation method; porous catalyst-particle; simulating and calculating; isothermal paralld reactions
