TL;DR: In this paper, a gaseous reaction mixture which contains hydrogen, olefins, diolefin, and aromatic compounds is subjected to a hydroforming operation, and subsequently the aromatics are separated in the substantially pure state from the hydroformate.
Abstract: In a process for producing substantially pure aromatics wherein a gaseous reaction mixture which contains hydrogen, olefins, diolefins and aromatic compounds is subjected to a hydroforming operation, and wherein subsequently the aromatics are separated in the substantially pure state from the hydroformate, the improvement which comprises cooling the hydroformate to a temperature of 100 to 400 DEG C directly after hydroforming and passing it still in gaseous state through a reactor filled with a hydrogenation catalyst under a pressure which differs from that under which the hydroforming operation was performed by not more than 10 atmospheres, whereby the olefins and diolefins are substantially eliminated.
