    Abstract: The invention relates to carrying out thermal cracking of hydrocarbons, or other thermal conversions of organic substances in a reactor, for which a suitable reaction time is extremely short, e.g. of the order of milliseconds. Particulate solids are used as heat carrier and as feed an organic substance is used in the form of a gas which may contain some liquid; the hot particulate solids are introduced at low or no velocity into contact with the gas, which is at substantially higher velocity; the solids accelerate in passing through the reactor but the reaction is terminated substantially before the solids attain the velocity of the product gas. Contact times are short so that the solids do not accelerate to erosive speeds. The velocity differential enhances the heat transfer rate which makes short reaction times feasible.

    Abstract: An integrated catalytic fluid coking and gasification process is provided in which a portion of the coke produced in the coker is steam gasified to produce a hydrogen-containing gas and a catalytic partially gasified coke. Subsequently, a portion of the catalytic partially gasified coke is burned to provide heated partially gasified coke which is recycled to the gasification zone. A portion of the catalytic partially gasified coke is passed from the gasification zone to the coker to contact the coker vapor phase product comprising normally liquid hydrocarbons and to crack at least a portion of the normally liquid hydrocarbons. Optionally, solid fines recovered from the gaseous effluent of the gasification zone may be recycled to the carbonaceous chargestock of the coker.

    Abstract: The quantity and quality of liquids produced from solid coal can be enhanced by a process comprising a liquefaction zone and a pyrolysis reactor, preferably a fluid coking zone, wherein the heavy liquids obtained in the pyrolysis reactor, e.g., 1000.degree. F.+ materials having a Conradson Carbon content of at least 15 wt. % are recycled to the liquefaction zone, rather than to the pyrolysis reactor, for further treatment under hydrogenation conditions and, consequently, conversion of the heavy liquids to lower boiling liquids which may be removed from the pyrolysis reactor feed by distillation is achieved.

    Abstract: A SUBSTRATE IS COKED BY CONTACT WITH OIL AT CRACKING TEMPERATURE, AND THE COKED SUBSTRATE IS THEN CONTACTED WITH SULPHUR OXIDES-CONTAINING GASES TO REDUCE THE SULPHUR OXIDES TO SULPHUR (WHICH IS RECOVERED) AND TO OXIDIZE COKE TO CARBON OXIDES. THE CRACKED OIL VAPORS ARE ALSO RECOVERED. THE PROCESS IS OPERATED EITHER CYCLICALLY. INTERMITTTENLY OR CONTINOUSLY.
