FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of producing isobutylene and butadiene-1,3 through catalytic dehydrogenation of corresponding paraffin hydrocarbons on a chromia-alumina catalyst at high temperature, separation of dehydrogenation products through absorption-desorption and extractive rectification, obtaining commercial-grade isobutylene and butadiene-1,3 of C4 olefin hydrocarbons, unconverted paraffins and combustible wastes: "light" and "heavy" unabsorbed gases and butadiene-acetylene concentrate, where the mixture of "heavy" unabsorbed gases with butadiene-acetylene concentrate and part of "light" unabsorbed gases is passed through a binary hydrogenation bed, one of which is nickel-chrome and the other aluminium-palladium, and a propane fraction is obtained at the output. ^ EFFECT: use of the given method increases utilisation of combustible wastes, obtaining a commercial-grade propane fraction through catalytic hydrogenation and longer service life of the catalyst. ^ 1 cl, 1 ex, 1 dwg |
