  • Patent number: 4770400
    Abstract: This invention is related to wood working, more specifically to repairing wooden and or other materials that have round or oval shapes, that have separated at old glue joints, or that have splintered or split. This invention will preferrably be used in conjunction with one-half or three-quarter inch pipe clamps and/or bar clamps, giving multiple clamping pressure points around any size circumference table top, desk top or any other object, circular or oblong. By using this invention, the object to be repaired can be subjected to the constant pressure needed around it's circumference to insure that a proper permanent bond forms between the separated or damaged pieces of wood or other related materials.

  • Patent number: 4508839
    Abstract: An improved process and catalyst for economically converting carbo-metallic oils to lighter products. This process is practiced in accordance with effective metals management, carbon management and catalyst activity management combined with feed atomization-vaporization, efficient stripping of carbonaceous material from the coked catalyst, exothermic and endothermic removal of hydrocarbonaceous material to effectively maintain the RCC unit in heat balance. This reduced crude cracking process is practiced with a new and improved catalyst composition identified as RCCC-1 Special that is characterized by the following composition; at least 30 wt % rare earth exchanged "Y" faujasite crystalline zeolite with a silica to alumina ratio of at least 5 of a high lanthanum to cerium ratio and residual sodium content less than 0.30 wt %, is provided with a pore volume greater than 0.35 cc/gm. and comprises a clay matrix material that may or may not be acidic with pore size openings in the range of 500 to 2,000 angstroms.

  • Patent number: 4470460
    Abstract: An improved method of in situ retorting of oil shale wherein a cavern of crushed shale is created within an oil shale deposit, preferably by igniting a powerful explosion within the oil shale deposit, thereby creating a localized area or cavern of rubblized oil shale. Combustion gases are injected into the bottom of this cavern and particulate material, preferably a cracking catalyst, is deposited into a void at the top of the cavern and allowed to trickle down and fill the voids in the rubblized cavern. The oil shale is ignited at the bottom of the cavern and a combustion zone proceeds upwardly while the particulate material is caused by gas flow to percolate downwardly. A fluidized bed of particulate material is thereby formed at the combustion zone providing a controlled, evenly advancing combustion zone.

  • Patent number: 4432890
    Abstract: A process is disclosed for the conversion of a hydrocarbon oil feed having a significant content of vanadium to lighter oil products by contacting the feed under conversion conditions in a conversion zone with a catalyst containing a metal additive to immobilize vanadium compounds. Conversion conditions are such that coke and vanadium are deposited on the catalyst in the conversion zone. Coked catalyst is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the coke and regenerated catalyst is recycled to the conversion zone for contact with fresh feed. The metal additive is present on the catalyst in an amount sufficient to immobilize the vanadium compounds in the presence of oxygen containing gas at the catalyst regeneration temperature.

  • Patent number: 4431515
    Abstract: A process for the production of high octane gasoline and/or valuable lower molecular weight products from carbometallic oils comprising contacting hydrogen and a carbometallic feed in a progressive flow reaction zone with hot conversion catalysts capable of activating hydrogen. The hydrogen gas may be introduced into the feed prior to or simultaneous with contacting the feed with catalysts. Alternately, the hydrogen gas may be introduced to the catalysts prior to or simultaneously with its contact with the carbometallic feed.

  • Patent number: 4425259
    Abstract: A process is disclosed for the conversion of high boiling oil feeds having a significant level of Conradson carbon components and metals to form lighter oil products by contacting the feed under catalytic conversion conditions with a catalyst containing one of a select group of metal additives to catalyze the endothermic removal of carbon with CO.sub.2. Conversion conditions are such that hydrocarbonaceous material and metals are deposited to deactivate the catalyst in the conversion zone. Deactivated catalyst is partially regenerated in the presence of carbon dioxide containing gas before or after oxygen regeneration at a temperature below 1600.degree. F. to provide a regenerated catalyst which is recycled to the conversion zone for further contact with fresh feed. The metal additive is present on the catalyst in an amount sufficient to catalyze the endothermic removal of carbonaceous material in the presence of a carbon dioxide rich gas at regeneration temperature below 1500.degree. F.

  • Patent number: 4417975
    Abstract: A process for economically converting carbo-metallic oils to lighter products. This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 to about 1400.degree. F., and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight.

  • Patent number: 4390415
    Abstract: A process is disclosed for the production of high octane gasoline and/or other valuable lower molecular weight products from carbo-metallic oils. Examples include crude oil, topped crude, reduced crude, residua, the extract from solvent de-asphalting and other heavy hydrocarbon fractions. These carbo-metallic oils contain quantities of coke precursors and heavy metal catalyst poisons substantially in excess of what is normally considered acceptable for FCC processing (fluid catalytic cracking) and substantial amounts of sulfur, nitrogen and other troublesome components may also be present. Such carbo-metallic oils are converted to the desired products in a catalytic conversion process. Named "RCC" (Reduced Crude Conversion) after a particularly common or useful carbo-metallic feed, the present process is by no means restricted to reduced crude or to oils of petroleum origin, having utility in the processing of oils from coal, shale and other sources.

  • Patent number: 4384948
    Abstract: A process for cracking a carbo-metallic oil feed having an initial boiling point of about 450.degree. F. or below comprising a naturally-occurring crude or a portion of such crude, including a portion boiling above 1000.degree. F. The 650.degree. F. portion is characterized by a carbon residue on pyrolysis of at least about 1 and containing at least about 4 ppm of Nickel Equivalents. The process comprises bringing the feed under cracking conditions in a progressive flow-type reactor into contact with a cracking catalyst bearing more than about 1500 parts per million of Nickel Equivalents of heavy metal(s). At least about 70% by weight of catalyst is abruptly separated from at least about 80% of the cracked products at the end of the reactor chamber.
