ABSTRACT:
The process relates to the production of olefins by thermal cracking, in the absence of a catalyst, of a fuel value residual hydrocarbon feedstock which, prior to cracking, is extracted with a paraffinic solvent which is selective for the saturated hydrocarbon material present in the feedstock. Preferred extraction conditions include the use of supercritical temperatures and pressures. The solvent is separated from the extracted hydrocarbon material and the latter is then cracked.
