In an emulsifier system for the tertiary recovery of oil comprising a surfactant and an alcohol cosurfactant, improved results are achieved if the alcohol cosurfactant is composed of a mixture of alcohols having no more than 12 carbon atoms.

Emulsifier system for the tertiary recovery of oil

Yields of liquid product produced by coking a feed material comprising a mixture of a shale oil material, a petroleum residuum and a hydrocracking catalyst, are enhanced by feeding hydrogen to the reaction system during the coking operation.

Catalytic hydrocoking of residua

The optimal salinity of an emulsifier system comprising an alcohol and a neutralized oxidized solvent extracted oil can be controlled to match the salinity of the brine used in the tertiary oil recovery process by controlling the acid number of the solvent extracted oil during the oxidation procedure, controlling the extent of the neutralization during neutralization of the oxidized solvent extracted oil, or both.

Technique for tertiary oil recovery

Liquid product yields produced by coking a mixture of a shale oil residuum and a petroleum residuum are improved by including in the feed to be coked a hydrogen catalyst.

Distillate yields by catalytically co-coking shale oil and petroleum

A new emulsifier system for use in the tertiary recovery of oil comprises a mixture of an alcohol having no more than 12 carbon atoms and a surfactant comprising a neutralized, oxidized solvent extracted oil.

Emulsifier system for tertiary oil recovery

Bitumen is separated from tar sands by contacting the tar sands with a small amount of liquid, heating the liquid treated tar sands to expand the liquid as a vapor thereby reducing the density of the bitumen and separating the bitumen from the remainder of the tar sands on the basis of density.

Recovery of bitumen from tar sands

Delayed coke especially manufactured for use in graphite can be effectively desulfurized by calcining in a hydrocarbon fuel-fired calciner in the temperature range of 2700.degree. F. to 2900.degree. F. without adversely affecting the strength of the coke or the coefficient of thermal expansion of the graphitized coke.

Process for the desulfurization of petroleum coke

Waste water produced in an acrylonitrile plant and containing significant amounts of acrylonitrile and acrylic acid is processed so as to reduce its organics content for disposal purposes and to recover the acrylonitrile and acrylic acid contained therein. The waste water is treated by contact with activated carbon to adsorb the organics contained therein. The activated carbon is periodicaly regenerated with a desorbing liquid and the desorbate product is distilled to yield acrylonitrile and acrylic acid. Every fifth regeneration cycle, the activated carbon is regenerated thermally rather than means of a liquid in order to restore its activity to its original value.

Treatment of acrylonitrile waste water with activated carbon

The present invention is an improved process for the recovery of bitumen from tar sand by employing a vessel containing a liquid comprising an organic phase consisting of a hydrocarbon solvent which is immiscible in water and an aqueous phase. The tar sand optionally containing water is introduced into the organic phase and then subsequently passes into the aqueous phase.

Tar sands recovery process

An improved process for the production in high yield of activated carbon particles of high activity comprises rapid removal of volatile material from the area of carbonaceous particles during the carbonization step by individually venting each hearth of a multiple hearth furnace. The carbonaceous particles which are subjected to the carbonization step are prepared from mixtures of carbonaceous material and petroleum acid sludge.
