Mineral oils: processes and products January USPTO class listing 01/08

20080023372 - Hydrocracking process: A catalytic hydrocracking process wherein a liquid phase stream comprising a hydrocarbonaceous feedstock, a liquid phase effluent from a hydrocracking zone, and a sufficiently low hydrogen concentration to maintain a liquid phase continuous system is fed into a hydrotreating zone to produce a first hydrocarbonaceous stream comprising hydrocarbons having a... Agent: Honeywell Intellectual Property Inc Patent Services

20080023373 - Method for extracting h2s from sour gas: This invention teaches a process that includes extraction of gas in which the presence of foam results in the carry over in the outlet gas stream of excessive liquids and/or solids, including the steps of injecting the foam laden gas stream tangentially into a cyclonic separator having an axial gas... Agent: Gable & Gotwals

20080017549 - Method of producing synthetic pitch: Embodiments of a method are described for modifying pitches, oils, tars, and binders by using these materials as solvents to extract organic chemicals from coal.... Agent: Dinsmore & Shohl, LLP

20080017550 - Piping: The invention relates to piping for use as a pyrolysis tube in a cracking furnace. The tube is formed such that it has at least one section whose centreline curves in three dimensions, to induce swirl flow in the tube. Preferably, the tube is formed as a helix, more preferably... Agent: Marshall, Gerstein & Borun LLP

20080017551 - Catalyst for hydrotreating hydrocarbon oil, process for producing the same, and method for hydrotreating hydrocarbon oil: There is provided a catalyst for hydrotreating a hydrocarbon oil, which comprises an inorganic oxide support containing a certain amount of phosphorus oxide having provided thereon: at least one selected from metals in the Group 6 of the periodic table, at least one selected from metals in the Group 8... Agent: Sughrue-265550

20080011643 - Use of field gas for pre-refining conventional crude oil into a pre-refined asphaltenes-free oil refinery feedstock pa and a liquid residual oil refinery feedstock pb: P

20080011644 - Ancillary cracking of heavy oils in conjuction with fcc unit operations: The production of light hydrocarbons consisting of ethylene, propylene, butylenes, and of gasoline is enhanced by introducing a heavy oil feedstream derived from an external source into an ancillary downflow reactor that utilizes the same catalyst composition as an adjacent FCC unit for cracking the heavy oil and withdrawing the... Agent: Abelman, Frayne & Schwab

20080011645 - Ancillary cracking of paraffinic naphtha in conjuction with fcc unit operations: The production of light hydrocarbons consisting of ethylene, propylene, butylenes, and of gasoline is enhanced by introducing a virgin paraffinic naphtha feedstream derived from an external source into an ancillary downflow reactor that utilizes the same catalyst composition as an adjacent FCC unit for cracking the naphtha and withdrawing the... Agent: Abelman, Frayne & Schwab

20080011646 - Reforming sulfur-containing hydrocarbons using a sulfur resistant catalyst: A method of reforming a sulfur containing hydrocarbon involves contacting the sulfur containing hydrocarbon with a sulfur tolerant catalyst containing a sulfur tolerant precious metal and a non-sulfating carrier so that the sulfur tolerant catalyst adsorbs at least a portion of sulfur in the sulfur containing hydrocarbon and a low... Agent: Amin, Turocy & Calvin, LLP

20080011647 - Hydrocracking catalyst containing beta and y zeolites, and process for its use to make distillate: Increased selectivity of middle distillate and/or increased catalyst activity are obtained in a hydrocracking process by the use of a catalyst containing a beta zeolite and a Y zeolite having a unit cell size of from 24.25 to 24.32 angstrom. The catalyst may also contain an additional Y zeolite having... Agent: Honeywell Intellectual Property Inc Patent Services

20080011648 - Hydrocracking catalyst containing beta and y zeolites, and process for its use to make distillate: Increased selectivity of middle distillate and increased catalyst activity are obtained in a hydrocracking process by the use of a catalyst containing a hydrogenation component, a beta zeolite having an overall silica to alumina mole ratio of less than 30 and a SF6 adsorption capacity of at least 28 wt-%,... Agent: Honeywell Intellectual Property Inc Patent Services

20080011649 - Hydrocracking catalyst containing beta and y zeolites, and process for its use to make distillate: Increased selectivity of middle distillate and/or increased catalyst activity are obtained in a hydrocracking process by the use of a catalyst containing a beta zeolite and a Y zeolite having a unit cell size of 24.33 to 24.38 angstrom. The catalyst may also contain an additional Y zeolite having a... Agent: Honeywell Intellectual Property Inc Patent Services

20080006561 - Dearomatized asphalt: This invention relates to a dearomatized asphalt. More particularly, an asphalt is extracted with a aromatic extraction solvent to produce an asphalt-rich phase and a solvent rich phase. The asphalt rich phase is stripped of solvent to produce dearomatized asphalt that has superior properties for paving and roofing applications.... Agent: Exxonmobil Research & Engineering Company
