    Abstract: A fluid coking process is provided in which a fresh carbonaceous feed is coked in a transfer line first coking zone positioned in a fluidized bed second coking zone. A heavy oil coker product is recycled to the fluidized bed second coking zone maintained at a lower temperature than the first coking zone. This process permits low severity coking of the fresh carbonceous feed and higher severity coking of the recycle oil, thereby minimizing conversion to coke and gas and increasing yield of normally liquid products.

    Abstract: A delayed coking process is conducted at a relatively low temperature with the introduction of a gas into the coking drum to strip volatile matter from the coke product and to form coke containing 6 to 12 weight percent volatile matter. Low temperature delayed coking decreases the amount of coke yield, calculated on a volatile-free basis, and increases liquid yield.

    Abstract: A delayed coking process is provided in which the fresh hydrocarbonaceous oil feed is divided into at least two streams. One stream is introduced directly into the preheating zone of the coking zone and one stream is introduced into the coker product fractionator. The fractionator bottoms fraction is recycled to the preheating zone as a separate stream from the fresh feed stream. The separate preheated fresh feed stream is introduced into the top of the coking zone and the preheated recycled fractionator bottoms fraction is introduced into the bottom of the coking zone. The given fresh feed splitting configuration permits decreasing the recycle rate of the heavy coker product and increasing liquid yield while the top and bottom feeding to the coking zone permit subjecting the given streams to different severity of coking.

    Abstract: A process for regenerating an alkylation catalyst comprising fluorosulfuric acid, said catalyst being at least partially deactivated, which comprises:(1) contacting at least a portion of the fluorosulfuric acid with water to form an acid-water mixture, thereby converting at least a portion of the fluorosulfuric acid therein to hydrogen fluoride and sulfuric acid;(2) removing at least a portion of the hydrogen fluoride from said acid-water mixture formed in step (1) by contacting same with a stripping agent to form a gaseous phase containing hydrogen fluoride and said stripping agent and a liquid phase containing sulfuric acid and sludge;(3) cooling the gas phase formed in step (2) to a temperature sufficient to form a mixed phase comprising at least a liquid phase containing hydrogen fluoride; and(4) treating the mixed phase formed in step (3) with sulfur trioxide under substantially liquid phase conditions so as to regenerate the fluorosulfuric acid. In a preferred embodiment, at least a portion of the regenerated fluorosulfuric acid is recycled to the alkylation zone for use as an alkylation catalyst therein.

    Abstract: An improved process for the production of higher octane number products by the high intensity mixing of alkylation media, or media wherein olefins are alkylated by the addition thereto of isobutane. The alkylation reaction is conducted by contact between the reactants, which constitute a hydrocarbon phase, and an acid catalyst which constitutes an aqueous phase, the reactants being dispersed as an emulsion. It is found that when stirring an alkylation medium at above a certain threshold fluid mixing intensity, a C.sub.6 + Motor Octane Number (MON) improvement ranging from about 0.5, and generally from about 0.5 to about 3.3, can be obtained by alkylating olefins with isobutane at high acid concentration while maintaining an acid soluble oil content ranging to about 3 percent, preferably from about 0.1 to about 3 percent, and more preferably from about 0.5 to about 2.5 percent, based on the weight of the reaction mixture, exclusive of the hydrocarbon phase. The alkylation is suitably conducted at acid strengths ranging from about 98 to about 88 percent, preferably from about 98 to about 94, based on the weight of the aqueous phase.
