Abstract: A stable free sulfur containing mineral oil is produced in a two-step process. The first step of the process comprises producing a sulfurized solubilizing oil by reacting a lubricant oil with elemental sulfur until the uncombined sulfur content is less than about 0.5%. The second step comprising dissolving in the oil a quantity of sulfur such that the final concentration of uncombined sulfur is less than 2.0%.

Abstract: This invention relates to the preparation of the subject aqueous solution from a non-bromine manganous salt. More specifically this invention pertains to a critical order of dissolving such salt and elemental bromine and to the use of an anti-oxidant for the manganous ion to prevent its conversion to hydrated manganous dioxide: MnO(OH).sub.2. According to "A Comprehensive Treatise On Inorganic And Theoretical Chemistry", J. W. Mellor, Vol. XII at pages 189 and 259 (published by Longmans, Green and Co., 1947) hydrated manganous dioxide results from the oxidation of a solution of manganous salt with chlorine, bromine, hypochlorous acid, hydrogen peroxide, etc. Such oxidation of a solution of manganous acetate was specifically mentioned. Such hydrated manganous dioxide is described as a white solid product which upon standing in contact with air becomes a dark brown to black product identified as MnO.sub.2.

Abstract: A method is disclosed for moving and eventually recovering oil from a subterranean oil-bearing formation which comprises injecting into the formation an aqueous fluid containing a succinamate surface-active agent and method for mobility control (imparting viscosity) to a surfactant system used for recovery or moving of oil in an oil-bearing formation.

Abstract: A catalytic composition is produced by reacting in an aqueous medium, vanadium and phosphorus compounds together with a hydrogen halide and removing liquid from the resulting reactants to form a solid which in an improved manner is heated at a temperature of about less than 470.degree. C. to effect liberation of water of hydration from the solid and thereafter contacting with a reducing material selected from the group of carbon monoxide, hydrogen and hydrogen sulfide at a temperature of from about 300.degree. to about 600.degree. C. and in the substantial absence of gaseous oxygen other than that liberated from the solid. The specific reduction step as taught and claimed herein improves catalyst activity performance by increasing the catalyst conversion and selectivity to a desired oxygenated product, and the ultimate yield of the oxygenated product per quantity of feed component converted. It also minimizes formation of inactive VPO.sub.

Abstract: Disclosed is a method for providing communication with a subterranean oil shale retort. This method can be used to provide a means of introducing fluids, such as a slurry of spent oil shale in water, into a retort. The method for providing lateral communication with a subterranean oil shale retort containing a rubblized retortable mass of oil shale, said retort being substantially surrounded by a mass of unmined formation comprises drilling at least one hole through the unmined formation adjacent to the retort; and providing communication between at least one of said holes and an adjacent retort; so that said drill hole can be used to communicate fluids to said retort. Fluids can be introduced into a spent retort which will form a supporting structure within said retort.

Abstract: There is disclosed a catalyst for the hydrodemetallization of petroleum hydrocarbon streams containing asphaltenes and large quantities of metals. This catalyst consists essentially of a small amount of a single hydrogenation metal selected from the group consisting of metals from Group VIB of the Periodic Table of Elements and metals from Group VIII of the Periodic Table deposed on a large-pore alumina. The hydrogenation metal may be present in the elemental form, as an oxide, as a sulfide, or mixtures thereof. The catalyst is characterized by a surface area of at least 120 square meters per gram, a pore volume of at least 0.7 cc per gram, and an average pore diameter of at least 125 Angstrom units. Suitable examples of a hydrogenation metal are nickel and molybdenum.

Abstract: The product of the reaction of an amine, an olefin and sulfur trioxide, or sulfur trioxide complex, is an effective ashless antistatic agent for hydrocarbons. A small amount of the antistatic agent, when added to hydrocarbons, increases the conductivity of the hydrocarbon. The increased conductivity of the hydrocarbon conducts away any static charges that may be generated on the hydrocarbon and thus prevents the buildup of the static charges. The antistatic additive is represented by the general formula ##STR1## where R.sub.1 is a hydrocarbon group of less than 24 carbon atoms and R.sub.2 is hydrocarbon group with less than 18 carbons, or ammonia.

The reaction is conducted under controlled temperature and pressure conditions.
