Abstract: A process for the preparation of a catalyst which is highly active for the synthesis of hydrocarbons from mixtures of hydrogen and carbon monoxide. A silica or silica-containing support is treated with a solution containing both an Iron Group metal, or metals, and nitrous acid, nitric acid, or a nitro-containing organo, or nitro-containing hydrocarbyl compound, or compounds, sufficient to hydroxylate the surface thereof and increase the number of hydroxyl groups on the surface of the support such that the metal component will be highly dispersed, this increasing the activity of the catalyst in a hydrocarbon synthesis reaction as contrasted with that of a catalyst of similar composition, similarly prepared except that the support component of the catalyst was not contacted and simultaneously treated with both the Iron Group metal and the acid.

Abstract: Small particle size catalysts having an average particle size of less than 20 or 10 microns, which agglomerate when contacted with a hydrocarbon liquid, are easily dispersed in the hydrocarbon liquid by first forming a mixture comprising the catalyst particles and one or more non-acidic, liquid polar oxygenates, such as an alcohol, ketone, ester, ether or mixture thereof. The mixture is contacted with the hydrocarbon liquid in which the particles then readily disperse. This process is useful for adding fresh or regenerated small particle size catalyst to catalytic hydroprocessing process slurries, including a reactive Fischer-Tropsch hydrocarbon synthesis slurry. One to four carbon atom alcohols are preferred oxygenates for use with a Fischer-Tropsch slurry.

The lubricating oil exhibits good resistance to wear, oxidation and rust, and reduced sludging at equipment surface temperatures of about 200.degree. F. and higher.

Abstract: A process for producing distillate fuels, such as diesel fuels and jet fuels having both high lubricity and low sulfur levels. Such fuels are produced by fractionating a distillate feedstream into a light fraction which is relatively low in lubricity and which contains from about 50 to 100 wppm of sulfur and a heavy fraction having a relatively high lubricity. The first fraction is hydrotreated to remove substantially all of the sulfur and is then blended with the second fraction to produce a distillate fuel product having relatively low sulfur levels and a relatively high lubricity.

Abstract: A lubricating oil suitable for machinery which may come into incidental contact with food is described, which contains a food grade base oil and a combination of food grade additives including a thickener, an antioxidant, a rust inhibitor, an anti-wear additive, an antifoamant, optionally a metal passivator, and 0.2 wt % or less coupling agent. The lubricating oil exhibits good resistance to wear, oxidation and rust, and reduced sludging at equipment surface temperatures of about 200.degree. F. and higher.

Abstract: TAN containing oils, e.g., crudes, are treated by flashing to remove substantially all of the water therefrom, thermally treating the recovered liquid to reduce the naphthenic acid content thereof, and re-combining light gases recovered from the flashing step with the treated liquid.

Abstract: Supports for Fischer-Tropsch catalysts with increased strength and attrition resistance are formed by incorporating both silica and alumina into a support comprised primarily of titania; whereupon Fischer-Tropsch active metals can be composited with the support; the catalysts being particularly useful in slurry reactions.

Abstract: A method for producing a process oil is provided in which an aromatic extract oil is added to a paraffinic rich feed to provide a blended feed. The blended feed is then extracted with an aromatic extraction solvent to yield a raffinate which subsequently is hydrotreated to provide a process oil.

Abstract: A gas distribution grid for a slurry reactor includes a plurality of gas injectors horizontally arrayed across, and extending through, an otherwise gas and liquid impervious plate. The injectors have a throat open at both ends, with a gas pressure reducing bore at one end which is the entrance end and with the other end opening into an upward opening cone. Flow diverting means in the injectors prevents slurry solids from entering the throat and being attrited by the high velocity gas jet exiting the bore into the throat. It is preferred that the gas injectors not protrude above the top surface of the grid and flat space is eliminated by means such as angular fillers, to prevent solids accumulation top of the grid. A chamfer may be present at the junction of the bore and throat to prevent unrestricted expansion of the gas jet entering the throat. This is useful for injecting gas into a reactive hydrocarbon synthesis slurry in a slurry reactor, with reduced catalyst attrition and deactivation.

Abstract: A container holds fluids, such as motor oil, and is sized to hold about one quart or one liter. The container has a rectangular base portion, and a top portion is formed integral with the base portion, the top portion being shaped like an offset, inverted funnel. The top portion has an opening forming a mouth, an outside edge of the mouth being in substantial alignment with a first side of the base portion. A concave, arcuate top panel extends from an opposing second side of the base portion to the mouth, and the top panel has a ridge along the center of its length for increasing top load strength and for providing a flow channel for fluid within the container.

The naphtha stream is contacted with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures from about 500 to 650.degree. C. and a hydrocarbon partial pressure from about 10 to 40 psia.

Abstract: Partially deactivated catalyst in a slurry hydrocarbon synthesis process is rejuvenated employing a cyclic rejuvenation process in which syngas or CO flow into the slurry is stopped to stop the hydrocarbon synthesis reaction, the CO purged out of the slurry with a purge gas in the presence of hydrogen, the catalyst rejuvenated with a hydrogen containing rejuvenating gas and the hydrocarbon synthesis reaction restarted by passing the synthesis gas feed back into the reactor. All or a portion of the purge gas and/or the rejuvenating gas may be recycled during the respective purge and/or rejuvenation. The hydrogen required during the purge is typically part of the purge gas.

These polymers are prepared by reacting a polymer containing halogenated paramethylstyrene units in the chain, e.g., a brominated copolymer of isobutylene and para-methylstyrene, with an anionically polymerized polymer made using an organolithium initiator compound having the formula R.sub.1 R.sub.2 Z R.sub.3 --Li where R.sub.1 and R.sub.2 are alkyl radicals, R.sub.3 is a direct link or an organic radical and Z is nitrogen or phosphorous. Reaction of the anionically polymerized polymer having an R.sub.1 R.sub.2 Z R.sub.3 --end group with the halogenated polymer leads to graft polymers coupled by a quaternary ammonium or phosphonium groups.
