A process for reducing the olefins and/or di-olefins content of a hydrocarbon-containing feed, such as that resulting from the thermal cracking of heavy oil, thermally cracked bitumen, or thermally cracked petroleum are disclosed. The process involves alkylation of di-olefins and olefins with aromatics already present in the hydrocarbon feed and without removal of nitrogen-, sulfur- or oxygen-containing compounds present in the feed. The process can take place without the need to add an external source of hydrogen, olefins or aromatics. |
