Time-resolved reaction chromatography was established to directly obtain the time-concentration response curve of the reactants passing through the column reactor. Application of catalytic reaction chromatography theoretical model to separate adsorption and surface reaction kinetics parameters. The effects of active components and carrier types on the dehydrogenation of cyclohexane and the kinetic parameters of thiophene hydrogenolysis were investigated. The results show that time-resolved reaction chromatography is an effective method that can be used to evaluate catalysts and to study adsorption and surface reaction kinetics.
