Investigation of the kinetics and mechanism of the dehydrogenation of isobutane on platinum-tin catalysts
An investigation has been made of the kinetics and mechanism for the dehydrogenation of isobutane on platinum-tin catalysts having different tin concentrations. It has been shown that the maximum activity is possessed by a catalyst containing 2% tin. On this catalyst the kinetic isotopic effect has been measured, in which the hydrogen was replaced by deuterium and the isotopic distribution has been measured for the exchange products between isobutane, isobutylene and deuterium. A stagewise system for the mechanism of the process and kinetic equations, proposed previously for the reaction on platinum and platinum-indium catalysts are fully applicable also to reactions on catalysts containing tin.
