Abstract:
A process for disposing of high sulfur-containing residual oil is disclosed wherein a high sulfur vacuum residual oil is hydrocracked and hydrodesulfurized in an upflow, high pressure, high temperature, ebullated bed reactor, the effluent fractionated, and the 975*F. fraction further subjected to separation by solvent extraction. The extract consists of gas oils, while the raffinate, containing most of the remaining sulfur, is partially oxidized to yield hydrogen which is recycled to the hydrocracking reactor. The heavy gas oil fraction from the extract may also be recycled to extinction in the hydrocracker.
Abstract:
The compounds are 2,6-methano-benzoxacins having pharmacological activity such as central nervous system activity and gastric acid secretion inhibitory activity. In addition, certain of the compounds, i.e., 2,6-methano-benzoxacin-4-ones, are useful as intermediates.
Abstract:
A first plurality or group of magnets is mounted in a housing in a pattern having a circular cross section. A second plurality or group of magnets is mounted in spaced relationship with respect to the first group and means are provided for moving one of the groups of magnets relative to the other. A conductive member is located in the space between the two groups of magnets, in the magnetic field therebetween. Rotation of the one group and variation in the flux causes the conductive member to become heated. A fluid is then directed past the member, in heattransfer relationship with respect thereto, to cause the fluid to be heated and useable as a working fluid.
Abstract:
Apparatus for establishing a substantially expanded electric arc discharge between a circulating electrode which includes the use of plasma guns, and a coacting stationary annular electrode through which the discharge effluents emerge. Means for introducing particulate material into the expanded arc discharge and operating the latter as an expanded arc furnace for various chemical reactions including the reduction and separation of ores, melting, refining, comminuting, spheroidizing and coating.
Abstract:
A PROCESS FOR THE SEMI-CONTINUOUS REGENERATION OF THE POISONED CATALYST IN A CLOSED, USUALLY HIGH PRESSURE SYSTEM. A PORTION OF THE CATALYST WHICH IS MAINTAINED IN AN EBULLATED BED IN A REACTOR, USUALLY UNDER HIGH PRESSURE, IS ALLOWED TO FLOW BY GRAVITY TO A CATALYST WASH VESSEL WHICH IS UNDER ESSENTIALLY THE SAME PRESSURE AS THE REACTOR. A WASH LIQUID IS FLOWED UPWARD THROUGH THE CATALYST IN THE WASH VESSEL TO WASH DEACTIVATING MATERIAL FROM THE CATALYST. ON COMPLETION OF CATALYST WASHING, FLOW OF THE WASH LIQUID IS INCREASED SUFFICIENTLY TO WASH AT LEAST A PORTION OF REGENERATED CATALYST BACK INTO THE REACTION. THE INVENTION FINDS PARTICULAR UTILITY IN A RESIDUAL OIL HYDROCRACKING HYDROSULFURIZATION PROCESS.
Abstract:
A PROCESS OF DRYING CLEANING TEXTILES AND GARMENT MATERIALS WITH COMPOSITIONS INCLUDING 1,1,2/TRICHLORO-1,2,2TRIFLUOROETHANE, TRICHLOROMONOFLUOROMETHANE, AND METHYL CHLOROFORM, WHEREIN THE MATERIALS ARE WASHED AND DRIED AT LOW TEMPERATURE, TOGETHER WITH STEPS OR PROCEDURES FOR THE ECONOMICAL HANDLING AND RECOVERY OF SOLVENT.
Abstract:
Gas lasers are described in which the tube is of metal. In one embodiment, the tube is of metal for substantially the complete axial length thereof between the electrodes, the tube being insulated from and at a floating electrical potential with respect to the electrodes. In a second described embodiment, the tube is made of a plurality of metal sections each being of optimum length to provide optimum electron temperature for maximum power output and being insulated from the other sections and from the electrodes.
Abstract:
PROCESS AND COMPOSITION FOR CLEANING TEXTILES AND OTHER GARMENT MATERIALS WITH A CHLORO-FLUOROHYDROCARBON SOLVENT HAVING A RELATIVELY HIGH FREEZING POINT WHICH PRODUCES A HIGH QUALITY OF CLEANING WITHOUT INJURY TO THE TEXTILES, AND IN WHICH THE SOLVENT CAN BE RECOVERED THROUGH CONDENSATION AND SOLIDIFICATION AT EASILY ATTAINABLE TEMPERATURES.
