| 摘 要： | 利用脉冲-应答技术,测定了糠醛在BHK-1催化剂上的传递与吸附系数和加氢反应速率常数。依据修正过的Kubin-Kucera气固相传质一维扩散模型,用单纯形法进行多维搜索的最优化方法来完成富里埃分析和时间域曲线拟合的计算。求得了六个参数:E、D_e、k_f、k_a、K_a、k_r,并对富里埃分析法和时间域曲线拟合法作了比较。

| Abstract: | Impulse-response experiments have been conducted to measure the mass transfer and absorption coefficients and the rate constant of furfural hydrogenation reaction over catalyst BHK-1. In this field, four or five analytical methods to solve the response peaks have deen proposed, among which the method of curve fitting in time domain is considered as the most accurate one. The purpose of this article is to evaluate model parameters with the help of simplex optimization method of poly-dimensional searching.Comparison was made between the results of calculation by Fourier analysis and those of curve fitting in time domain. The selection of harmonic number and period to be used is also discussed. |
