The domestic technology of olefin production is mainly organized by the method of dehydrogenation of paraffins in a fluidized bed on an alumochrome catalyst circulating in a reactor-regenerator system. Currently, the leading enterprises of the oil and gas industry producing olefin hydrocarbons are conducting a two-stage method of dehydrogenation of paraffin hydrocarbons. In this paper, the possibility of dehydrogenation of butane – isobutane-containing fractions without their preliminary separation on the surface of an alumochrome catalyst is studied. The activity of the catalyst for the release of olefins on the skipped paraffins was evaluated, as well as the selectivity of the process for the release of olefins on decomposed paraffins, taking into account the volumetric feed rate of raw materials at standard temperature conditions. As a result of the joint dehydrogenation of butane: isobutane in a threefold excess of n-butane, there is an increase in total activity and selectivity when testing pure n-butane separately.
