Abstract: A method of reducing hydrolysis in a hydrocarbon stream comprising adding to a hydrocarbon stream containing a chloride compound which undergoes hydrolysis at elevated temperatures in the presence of water to form hydrochloric acid, an effective amount of a treating agent that is at least one overbased complex of a metal salt and an organic acid complexing agent, the treating agent being added to hydrocarbon stream when the stream is at a temperature below which any substantial hydrolysis of the chloride containing compound occurs.

Abstract: The invention is a low viscosity oil composition derived from crude oils and crude oil residuum comprising dispersed asphaltene salts in a hydrocarbon continuous phase.

Abstract: The invention describes a method for decreasing the viscosity of crude oils and residuum utilizing a combination of acid and sonic treatment.

Abstract: A metal spring with embedded constrained layer damping provides effective damping of a supported load. A continuous load bearing tube is provided with an inner diameter and an outer diameter with a plurality of constraining layer tube sections concentric with the load bearing tube and spaced along the load bearing tube. A damping layer of a viscoelastic material contacts facing surfaces of the continuous load bearing tube and the constraining layer tube sections so that shear strains are induced in the viscoelastic material from relative rotation of the load bearing tube and the constraining layer sections to provide damping of an applied load. In one embodiment, the constraining layer tube sections and damping are within the load bearing continuous tube and the continuous tube is sealed at each end to permit use of the spring in a vacuum environment.

Abstract: According to the invention, the oil is passed through a pulverulent material, such as an earth or clay, in the presence of an acid. The pulverulent material can be placed beforehand on a filter or can be mixed with the oil before filtration. If necessary, the oil is recycled through the filter up to complete decontamination.Application to the radioactive decontamination of oils used in the nuclear industry.

Abstract: The present invention provides a method for reprocessing, particularly the dehalogenation, of oil products which involves a) treating the oil product at temperatures up to about 150.degree. C. with an effective amount of an aqueous solution of at least one compound selected from the group consisting of a strong acid, a salt of a weak base and a strong acid and precursors thereof; b) treating the oil product of step (a) at increased temperatures with at least one halogen binding agent; and c) separating water and/or the solids from the treated oil product of step (b).

Abstract: Hydrocarbon feedstocks containing relatively high levels of nitrogen contaminants are converted by catalytic cracking to products of lower average molecular weight by contacting the feedstock with a mixture of a cracking catalyst and separate particles of a nitrogen scavenger comprising microporous solids selected from the group consisting of acid clays; hydrogen or ammonium exchanged mordenite, clinoptilolite, chabazite and erionite; mineral acids or mineral acid precursors supported on an inorganic, refractory oxide; and Catapal alumina.

Abstract: A combination process for upgrading hydrocarbon fractions obtained from raw shale oil, oil products of coal processing and select fractions of crude oils comprising sulfur, nitrogen and metal contaminants to produce jet fuel product fractions such as JP4, JP5, JP8 and other turbine-type fuel materials provided. The combination of integrated processing steps involving hydrotreating, acid extraction of basic nitrogen compounds and hydrofining thereof to produce a feed composition suitable for catalytic reforming in the absence of significant hydrocracking whereby jet fuel boiling range material is produced significantly reduces by the combination the hydrogen requirements of the process.

Abstract: In a process for producing alkylaromatics by halogenating a paraffin and reacting the halogenated paraffin with an aromatic hydrocarbon, the rate of halogenation is improved by treating the n-paraffin to selectively remove oxygen-containing hydrocarbonaceous compounds from the n-paraffin with a sorbent selective for such oxygen-containing compounds, and subsequently halogenating the treated n-parffin. The improvement is particularly useful in producing alkylaromatic hydrocarbons from monocyclic aromatic compounds and n-paraffins.
