| Abstract: | 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. |
