FIELD: chemistry.
SUBSTANCE: invention relates to a catalyst for the dehydrogenation of paraffins, as well as a method of dehydrogenating paraffins using this catalyst. The proposed catalyst contains a first component selected from the group consisting of noble metals of group VIII and mixtures thereof, a modifier selected from the group consisting of alkali metals or alkaline earth metals and mixtures thereof, and a third component selected from the group consisting of tin, germanium, lead, indium, gallium, thallium and mixtures thereof, as well as a carrier forming a catalyst particle containing many pores. The catalyst has a modifier profile index in the range from 1 to 1.4 over the entire catalyst particle.
EFFECT: provision of a dehydrogenation catalyst that produces less coke in the dehydrogenation operation of both propane and isobutane, is more selective towards isobutylene and produces fewer undesirable products.
