Abstract
A hydrocarbon conversion process comprises pyrolysing at a temperature ≥700° C. a feedstock comprising hydrocarbon to produce a pyrolysis effluent comprising at least one Cto Colefin and Caliphatic and aromatic hydrocarbons. The pyrolysis effluent is contacted with an oleaginous quench stream to reduce the temperature of the pyrolysis effluent to ≤400° C. At least first and second streams are separated from the cooled effluent. The first stream comprises at least one Cto Colefin, and the second stream comprises a quench oil having an average boiling point at atmospheric pressure of at least 120° C. At least a portion of the second stream is catalytically hydroprocessed to produce a hydroprocessed stream, which is combined with at least a portion of any remainder of the second stream to form the quench stream.
