摘要
本文运用脉冲-应答技术,在不同温度和不同流速条件下测定了糠醛在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-维扩散模型,采用比较准确的Fourier分析法处理实验结果,并通过最优化计算求得了E、D_e、K_f、k_a、K_a、K_r,等6个参数.
The impulse-response experiment was conducted to measure the mass transfer and adsorption coefficients and the rate constant of furfural hydrogena-tion reaction over catalyst BHK-1. The results showed that adsorption equilibrium constant, adsorption rate constant and surface reaction rate constants Ka, ka and Ki and interpartide diffusivity De did not change with the flow rate of the carrier and that adsorption heat, adsorption energy and surface reaction energy were 15.7, 29.4 and 43.8kJ/mol respectively.
