Previous research has examined the question concerning the effect of absorption kinetics on the nature of the catalytic process taking place under chromatographic conditions. Some new results in this direction are contained in this report. The authors proceeded from the fact that essential information about the course of the catalytic process is also given, along with the peak areas of the reactants, by information about their position and form from which the state of the reactants on the catalyst surface can be judged. It is possible to calculate the rate constants of the reactions, adsorption, and desorption with this information. The experimental difficulty consists of the fact that the bands of reactants and products during motion along the catalyst layer mutally overlap and, from the yield curves taken directly after the reactor, it is usually difficult to determine the parameters of the peaks of the separate components of the reaction mixture. In this work the method of chromatographic scanning is described, making it possible to bypass these difficulties.
