测定糠醛的传递与吸附系数和加氢反应速度常数

Evaluating Transfer and Adsorption Coefficients and Hydrogenation Reaction Rate Constant of Furfural by Impulse-Response Technique

脉冲-应答技术广泛应用于多相催化研究中求取传递与吸附系数和动力学常数。采用单离散模型,应用该技术研究了糠醛加氢反应,获得了糠醛在催化剂BHK-1上的轴向扩散系数E、吸附平衡常数K_a和反应速率常数k_r。

The impulse-response technique is widely used for heterogeneous catalysis study to evaluate transfer and adsorption coefficients and kinetic constant. Based on a dispersion model with the help of this experiment technique the furfural hydrogenation reaction has been studied to obtain axial disperson coefficient E, adsorption equilibrium constant K_a and reaction rate constant k_r of furfural over catalyst BHK-1 in a fixed-bed reactor.
