This kinetic study was performed in a flow-pressurized micro-reverse-chromatographic device. The reaction conditions are as follows: the reaction temperature is 390-420 DEG C, the pressure is 0.3-1.6MPa, the liquid space velocity is 20-100h-1, the molecular ratio of hydrogen and cyclohexane is 8: 1, the reactor is charged with a particle size of 40- 60 purpose catalyst 0.102g, the reaction results were excellent microprocessor processing. The kinetic model of cyclohexane dehydrogenation is a two-position central mechanism of LH activity. The initial velocity equation of the reaction is r_0 = (k_aK_c (P_c ~ 0) ~ 2) / ([1 + K_c (P_c ~ 0) ~ 2 + K_H K_a = 1.2384 × 10 ~ 7exp (-11100 / T) (mol / g · h) K_c = 7.3178 × 10 ~ (-4) exp (8534.776 / T) MPa -2 and the reaction activation energy E = 91.90 (KJ / mol) cyclohexane adsorption heat Q = 70.66 (KJ / mol)
