Abstract:
A process for producing liquid fuels from heavy hydrocarbons such as residual oil in which the cracking temperatures are in the range of 800.degree. F. to 1200.degree. F., and the residence times are between 0.05 seconds and 0.50 seconds.
Abstract:
A process for contemporaneously catalytically cracking a paraffin rich feedstock and a heavy feedstock wherein the feedstocks are segregated prior to catalytic cracking in separate reactors with regenerated particulate catalyst solids. The process provides for the separate optimal cracking of paraffinic constituents and heavy naphthenic constituents while maintaining an overall heat balance.

Abstract:
A process for producing improved yields of aromatics (benzene, toluene, xylene) by initially partially thermally cracking heavy hydrocarbon and thermally cracking ethane to high conversion and then completely cracking the partially cracked heavy hydrocarbon with the completely cracked ethane.
Abstract:
A process and system for the production of olefins from heavy hydrocarbon feedstocks. A heavy hydrocarbon feed is first pretreated at high pressure and moderate temperatures to preferentially remove coke precursors in a liquid product. The pretreated hydrocarbon is then separated into lighter and heavier fractions; the lighter fraction being further thermally cracked to produce olefins.
Abstract:
A process for cracking heavy hydrocarbon feedstocks by separation into light and heavy fractions and concommitantly thermally cracking the light fraction and coking the heavy fraction.
Abstract:
An improved process and apparatus for generating fuel gas and decoking particulate solids used as the source of heat to effect chemical reactions in a TRC system.
