Abstract: A coated cathode material comprises a lithium metal oxide particulate having a surface at least partially coated with a coating comprised of a complex metal oxide of aluminum and a second metal that is lanthanum, yttria or combination thereof. The coated cathode material may be made by providing a lithium metal oxide particulate which is then contacted with a precursor compound that forms a complex metal oxide upon heating. The coated lithium metal oxide is then heated to a temperature sufficient to form the complex metal oxide, wherein the complex metal oxide is amorphous and contains aluminum and a second metal that is lanthanum, yttria or combination thereof and the complex metal oxide is bonded to the lithium metal oxide.

Abstract: LMFP cathode materials are made in a mechanochemical/solid state process. The precursors are dried in a preliminary step to reduce the water content of the precursors of less than 1% by weight and preferably less than 0.25% by weight. The dried precursors are then dry milled and calcined to form particles of an olivine LMFP. The product has excellent specific capacity and capacity retention.

Abstract: A supported catalyst and process for dehydrogenating a hydrocarbon, the catalyst comprising a first component selected from the group consisting of tin, germanium, lead, indium, gallium, thallium, and compounds thereof; a second component selected from the group consisting of metals of Group 8 of the Periodic Table of the Elements and compounds thereof, and a support comprising alumina in the gamma crystalline form. The catalysts are especially active and efficient when employed in concurrent flow in a dehydrogenation reactor having an average contact time between the hydrocarbon and catalyst of from 0.5 to 10 seconds.

Abstract: A process for producing vinyl chloride monomer from ethylene and ethane having input of significant quantities of both ethane and ethylene in input streams to the affiliated reactor where hydrogen chloride in the reactor effluent is only partially recovered from the reactor effluent in the first unit operation after the ethane/ethylene-to-vinyl reaction step or stage. Steps are presented of oxydehydro-chlorination catalytic reaction of ethane, ethylene, hydrogen chloride, oxygen, and chlorine; cooling and condensing the reactor effluent stream; and separating the condensed raw product stream into vinyl chloride monomer and a reactor recycle stream.

Abstract: This invention is a process for producing vinyl chloride from an ethylene-containing feed, oxygen, and a chlorine source in the presence of a catalyst. The process permits direct production of vinyl chloride in a single reactor system, and further permits ethane to be used as the C2 hydrocarbon feed with recycle of ethylene from the product stream to constitute the ethylene specified for the feed. This invention in another aspect concerns also a composition of matter, and a method for making the composition, wherein the composition is useful as a catalyst for the vinyl chloride process. The composition comprises a rare earth-containing material, with the proviso that the catalyst prepared therefrom is substantially free of iron and copper and with the further proviso that when cerium is present the catalyst further comprises at least one more rare earth element other than cerium.

Abstract: A process for producing vinyl chloride monomer where significant quantities of both ethane and ethylene in input streams to the affiliated reactor where hydrogen chloride in the reactor effluent is essentially fully recovered from the reactor effluent in the first unit operation after the ethane/ethylene-to-vinyl reaction step or stage. Steps are presented of oxydehydro-chlorination catalytic reaction of ethane, ethylene, hydrogen chloride, oxygen, and chlorine; quenching the reactor effluent stream to provide a raw product stream having essentially no hydrogen chloride; and separation of the raw product stream into a vinyl chloride monomer product stream and into a lights stream; and recycling the lights steam to the reactor.

Abstract: A vapor deposition method for coating a substrate with a porous zeolitic film. The method includes two steps. The first step is to irradiate a zeolite with a pulsed laser beam to vaporize the zeolite in a plume adjacent to the zeolite. The second step is to intercept the plume on the substrate to form the porous zeolitic film. A piezoelectric substrate can be used to produce a chemical sensor.

Abstract: A process for producing dialkyl carbonates which comprises contacting an alkanol, carbon monoxide, and oxygen with a catalyst to produce dialkyl carbonate, the catalyst having been prepared by heating a solid copper compound in the presence of a zeolite to form a zeolite containing copper.

Abstract: A process of recovering monoalkylbenzene and pure 1,3,5-trialkylbenzene from an isomeric mixture containing dialkyl- and trialkylbenzenes. The process comprises transalkylating a monocyclic aromatic compound with a mixture of dialkyl- and trialkyl-benzenes in the presence of an acidic mordenite zeolite under conditions such that monoalkylbenzene and predominantly 1,3,5-trialkylbenzene are formed. 1,3,5-trialkylbenzene is isolated in pure form from a mixture of the same and 1,2,4- and/or 1,2,3-trialkylbenzene by use of a dealuminated zeolite Y adsorbent.

Abstract: A process for the cyclodimerization of 1,3-butadienes to 4-vinylcyclohexenes comprising contacting a butadiene in the presence of a promoting amount of a hydroxylic solvent with a catalyst containing copper(I) ions supported on a carrier.

Abstract: A process of separating the ortho, meta and para isomers of ethyltoluene. One aspect employs a ferrierite absorbent which separates the para isomer from a mixture of the same and at least one of the meta and ortho isomers. A second aspect employs a silicalite absorbent which separates the ortho isomer from a mixture of the same and the meta isomer. A third aspect combines the ferrierite and silicalite absorbents in sequence to separate a mixture of the ortho, meta and para isomers into the essentially pure compounds.
