Abstract

1. A process for the production of thermally stable pitches from residues of the petrochemical processing containing highly aromatic, unsaturated compounds, characterised by mixing the highly aromatic residues with residues from the hydrogenation refining boiling between 150 and 280 degrees C at a ratio of 1:0,02 to 1:0,25 and heating to a temperature between 350 and 400 degrees C under the pressure which develops during said heating, and rectifying the reaction product under atmospheric or reduced pressure to obtain fractions of aromatics and a pitch with a softening point of at least 50 degrees C, measured according to Kraemer-Sarnow.
