Beschreibung
Zusammenfassung:	FIELD: petrochemical syntheses. SUBSTANCE: isopentane is dehydrogenated to form contact gas consisting of mixture of saturated and unsaturated $$$-hydrocarbons which are further subjected to oligomerization to give product containing di- and trimmers of unsaturated $$$-hydrocarbons. Product is rectified to yield mixture of above-indicated di- and trimmers and mixture of saturated and unsaturated $$$-hydrocarbons. From the latter, isopentane fraction and fraction containing unsaturated $$$- hydrocarbons are isolated. The second fraction is divided into two streams, one of them being returned into the dehydrogenation stage and the other, jointly with catalyst, is directed into oligomerization stage. EFFECT: extended utilization area for unsaturated $$$-hydrocarbons.
