Abstract

Способ получения олефиновых углеводородов С4 каталитическим дегидрированием соответствующих парафиновых углеводородов на алюмохромовом катализаторе при повышенной температуре разделением полученных продуктов дегидрирования методами абсорбции-десорбции и экстрактивной ректификации с получением товарных олефинов, непревращенных парафинов и горючих отходов производства: «легких» и «тяжелых» неабсорбированных газов и бутадиен-ацетиленового концентрата, отличающийся тем, что смесь «тяжелых» неабсорбированных газов с бутадиен-ацетиленовым концентратом и частью «легких» неабсорбированных газов пропускают через бинарный слой катализаторов гидрирования, один из которых никель-хромовый, а другой алюмопалладиевый и на выходе получают пропановую фракцию.The method of producing C4 olefin hydrocarbons by catalytic dehydrogenation of the corresponding paraffin hydrocarbons on an aluminum chromium catalyst at an elevated temperature by separation of the obtained dehydrogenation products by absorption-desorption and extractive rectification methods to obtain marketable olefins, unconverted paraffins and combustible waste products: “light” and “heavy” non-absorbed gases and butadiene -acetylene concentrate, characterized in that the mixture of "heavy" non-absorbed gases with butadiene-ace ylene concentrate and part of the "light" unabsorbed gases are passed through a binary layer of hydrogenation catalysts, one of which the nickel-chromium, and other alyumopalladievy and outlet propane fraction is obtained.
