Abstract: Method of contacting a hydrocarbon feed with a catalyst that includes one or more metals from Column 6 of the Periodic Table and/or one or more compounds of one or more metals from Column 6 of the Periodic Table and a support. The support comprises from 0.01 grams to 0.2 gram of silica and from 0.80 grams to 0.99 grams of alumina per gram of support. The catalyst has a surface area of at least 340 m2/g, a pore size distribution with a median pore diameter of at most 100 ?, and at least 80% of its pore volume in pores having a pore diameter of at most 300 ? or the catalyst exhibits one or more peaks between 35 degrees and 70 degrees, and at least one of the peaks has a base width of at least 10 degrees, as determined by x-ray diffraction at 2-theta.

Abstract: The present invention relates to methods and systems for removing polar molecule contaminants from a refinery stream in connection with the processing of hydrocarbon fluids, chemicals, whole crude oils, blends and fractions in refineries and chemical plants that include adding high surface energy and/or high surface area nanoparticle compounds to a refinery stream to remove the polar molecule contaminants.

Abstract: A novel process for cracking olefins including contacting a hydrocarbon oil with a catalyst in a riser reactor having multiple reaction zones under cracking reaction conditions; separating reaction products and the catalyst; regenerating at least a part of spent catalyst obtained, contacting a part of the regenerated catalyst with the hydrocarbon in the first reaction zone; contacting the other part of the spent catalyst and/or regenerated catalyst in at least one reaction zone after the first reaction zone with the products obtained in previous reaction zones.

Abstract: The invention relates to the processing of waste, contaminated, or raw materials. Crude oil can be processed to purify oil and separate water.

Abstract: Sulfur-containing petroleum feeds are desulfurized by contacting the feeds with staged addition of sodium metal at temperatures of at least about 250° C. in the presence of excess hydrogen to sodium metal. The formation of Na2S is substantially suppressed and the formation of NaSH is promoted in the desulfurization process.

Abstract: Reducing the ash content of hydrocarbonaceous materials containing bound oxygen by reaction with an oxygen deficient source of an oxygen-reactive element, except oxygen and hydrogen, preferably an oxygen deficient compound of silicon.

Abstract: The present invention relates to a method of treating a hydrocarbon fuel to minimize the consumption of the fuel, in which a magnet having a very weak magnetic flux density, and the magnetic density at the S pole is larger than that at the N pole is used, and using the magnet of the present invention the fuel cost can be reduced to about 70-80% in comparison with the non-treated fuel.

Abstract: Trialkyl arsines are removed from fluids, in particular gases, by contacting with a solid sorbent material containing at least one silver component (preferably nitrate and/or oxide and/or metal) and a support material (preferably alumina, fluorided alumina, silica, fluorided silica, titania or magnesium aluminate).

Abstract: An oil characteristic improvement process and device therefor including methodology whereby the specific gravity and viscosity of heavy oil feedstock is reduced. The process includes the steps of forming a mixture of the heavy oil feedstock and one or more organic reagents having a terminal hydroxyl group and heating the mixture from 300.degree. F. to 750.degree. F. in a reactor vessel while simultaneously exposing the mixture to a ferrous metal. In connection with this process, the present invention is also directed to a tubular reactor vessel, the inner walls of which include ferrous metal, the inner diameter and length of the tubular vessel being chosen such that the flow rate of the heavy oil through the vessel is such that the residence time within the vessel ranges from 600 to 6000 seconds, the heat flux through the walls of the vessel is less than 20,000 BTU/hr/sq.ft.

Abstract: This disclosure is directed to strengthening carbon black-particulate "Teflon" (PTFE) mixes destined to be formed into active layers in air cathodes, which comprises forming the carbon black-particulate Teflon mix; fibrillating said mix along with a substantial quantity of soluble pore-forming agent; adding polytetrafluoroethylene (PTFE) fibers while chopping said fibrillated mix; and thereafter rolling said chopped fibrillated mix containing said PTFE fibers into sheet form.

Abstract: A method for reprocessing used lubricating oils is disclosed wherein the oil is dried, treated with finely dispersed sodium metal at elevated temperature, the remaining free or organically bound metal is decomposed by means of an active hydrogen containing compounds, followed by distillation of the oil for recovery.
