Изобретение касается производства низших олефинов, таких как изобутилен, пропилен и может быть использовано в нефтехимии. Для увеличения выхода олефинов при дегидрировании соответствующих парафинов в присутствии диоксида серы и катализатора процесс ведут на коксовых отложениях, образующихся при обработке кремнийсодержащих носителей C3 - C4 парафинами или их смесью с диоксидом серы при температуре 650 - 750oC, и составляющих 3 - 40% от массы носителя. При проведении процесса при температуре 550 - 680oC и времени контакта 2 - 20 с способ обеспечивает выход изобутилена 43 - 76% при селективности 65 - 85% и конверсии изобутана 60 - 90%.The invention relates to the production of lower olefins, such as isobutylene, propylene and can be used in petrochemicals. To increase the yield of olefins during the dehydrogenation of the corresponding paraffins in the presence of sulfur dioxide and a catalyst, the process is conducted on coke deposits formed during the processing of silicon-containing carriers C 3 - C 4 with paraffins or their mixture with sulfur dioxide at a temperature of 650 - 750 o C, and components 3 - 40 % by weight of the carrier. When carrying out the process at a temperature of 550 - 680 o C and a contact time of 2 - 20 s, the method provides an isobutylene yield of 43 - 76% with a selectivity of 65 - 85% and an isobutane conversion of 60 - 90%.
