Abstract

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.
