摘要： A method of separating and selectively removing hydrogen contaminant from hydrogen-containing product and by-product process streams is disclosed. Separation and removal occur when certain Cd-exchanged zeolite rho compositions are placed in contact with a hydrogen-containing process stream. A hydrogen-encapsulated zeolite rho composition is formed by practice of the method.

摘要： A process is disclosed for converting a spent catalyst from conventional fluorination processes into a commercially useful tantalum or niobium salt such as K2TaF7 or K2NbF7. The process broadly relates to dissolving the spent catalyst in water or an aqueous hydrofluoric acid solution, separating and disposing the undissolved residue, extracting the aqueous solution with a suitable solvent such as methyl isobutyl ketone (MIBK), and obtaining useful tantalum products from the MIBK solution such as a tantalum salt.

摘要： The present invention relates to a process for friction welding molybdenum-rhenium alloys which include from about 10 % to about 50 % by weight. The process of the invention comprises effecting a relative rotation of two MoRe workpieces at rim surface speeds up to about 4,000 to 8,000 inches per minute, forcing the workpieces into frictional contact under an axially applied pressure of about 3,000 to 20,000 pounds per square inch of interface surface.

摘要： The invention provides for sprayable powder comprising friable granules of agglomerated primary particles of non-fibrillatable fluoropolymer and, optionally, at least one other component, the powder having a bulk density of at least 20g/100cc and average particle size of 5 to 100 micrometers. The sprayable powder is preferably free of water immiscible liquid, and more preferably free of halocarbon liquid. Included among the other components are inorganic fillers, pigments, high temperature resistant polymer binders. In an other embodiment, the invention provides for a sprayable powder comprising friable granules of agglomerated primary particles of a first non-fibrillatable fluoropolymer and at least one other non-fibrillatable component. The invention further provides for a process for preparing the sprayable powder by spray drying a liquid dispersion. In a preferred embodiment, the process includes densifying the granules of agglomerated primary particles that result from spray drying. Densifying may be carried out by mechanical compaction or by contacting the granules with a heated gas to form a fluidized bed. Optional steps of communication and heat treatment may be employed to achieve a desired bulk density and particle size for specific applications.

摘要： The present invention relates to the discovery of compositions which include fluoroethane, 2-fluoropropane or tert-butylfluoride. These compositions are useful as pure components or with at least one of tetrafluoroethane, difluoroethane, hexafluoropropane, a hydrocarbon or dimethylether. These compositions are useful as aerosol propellants, refrigerants, cleaning agent, expansion agents for polyolefins and polyurethanes, refrigerants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents.

摘要： Disclosed is a process for the separation of tar and non-volatile reagents from a reaction mixture formed when chlorinated carbon compounds are allowed to react with anhydrous hydrogen fluoride in a liquid phase to form fluorinated carbon compounds. The disclosed process leaves tar essentially free of HF and in a form allowing for safe, easy, and economical transfer and disposal.

摘要： A process and a system uses a direct chlorination reactor for producing ethylene dichloride by direct chlorination, without the need for an oxychlorination unit. This ethylene dichloride may be used to make vinyl chloride monomer. In the process for making ethylene dichloride, ethylene and chlorine are both supplied to a direct chlorination reactor. The ethylene reacts with the chlorine to form ethylene dichloride. Chlorine is supplied to the direct chlorination reactor from an electrochemical cell which converts anhydrous hydrogen chloride to dry chlorine gas. This chlorine gas is purified and liquefied to form liquid dry chlorine, and the liquid dry chlorine is recycled to the direct chlorination reactor. The ethylene dichloride may be pyrolyzed to produce vinyl chloride monomer and anhydrous hydrogen chloride.
