KINETICS OF THE DEHYDROGENATION OF N-BUTANE AND ITS MIXTURES WITH PROPANE OVER PLATINUM CATALYSTS

The kinetics of the dehydrogenation of n-butane and its mixtures with propane over potassium-platinum catalysts and those modified by indium was investigated. The addition of indium resulted in an increase in t he rate and selectivity of dehydrogenation. The stepwise scheme was su ggested to take into account the parallel and consecutive formation of butadiene on two types of centers. A simple, mutual influence of comp onents was found to occur in the case of dehydrogenation of propane-bu tane mixtures. The dehydrogenation rates of i- and n-butanes were comp ared.
