Abstract

Inventia se refera la un procedeu pentru obtinerea unui concentrat de diciclopentadiena dintr-o fractiune C5/C6, care rezulta ca fractiune lichida la piroliza hidrocarburilor, concentrat utilizabil în producerea rasinilor sintetice. Se stie ca scopul pirolizei hidrocarburilor (KW) lichide sau gazoase este obtinerea preferentiala a olefinelor inferioare. Prin aceasta precipita o multitudine de produse de piroliza care ajung de la vapori de apa pîna la hidrocarburi cu puncte înalte de fierbere. într-o instalatie de separare conectata la o instalatie de piroliza se separa produsele de piroliza formate corespunzator starii lor la fierbere prin condensare fractionala si distilare.
