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.

A method for making submicrometer metallic carbides and submicrometer solid solution metallic carbides from sources of at least one metallic oxide and carbon involves the rapid heating of a reactive particulate mixture of at least one metallic oxide and carbon in order to achieve a resulting particulate size of less than 1 micrometer. Submicrometer sized metallic carbides and solid solution metallic carbides have found great use in commercial ceramic applications. It has been found that the smaller sized particles produce a product having superior toughness and hardness. In addition, the submicrometer sized solid solution metallic carbide resulting from this method is also disclosed.

The preparation of vinyl halide monomer, and further to polyvinyl halide, starting from Ccompounds, involving conversion of methane or methanol to methyl halide; condensation of methyl halide to ethylene and co-product hydrogen halide; oxidative halogenation of ethylene to vinyl halide monomer; separation of vinyl halide monomer from any methyl halide present in the vinyl halide monomer stream; optional recycling of the methyl halide recovered to the condensation step; and recovery and optional recycling of the co-product hydrogen halide. Optionally, the vinyl halide monomer may be polymerized to polyvinyl halide to facilitate separation of the monomer from methyl halide. Methyl halide may be obtained via oxidative halogenation of methane in the presence of a rare earth halide or rare earth oxyhalide catalyst. Optionally, the methyl halide may be converted to methanol.

In one aspect, a process for producing vinyl chloride from ethane/ethylene involving: (a) combining ethane, ethylene, or mixtures thereof with an oxygen source and a chlorine source in a reactor containing a suitable catalyst under conditions sufficient to convert substantially all of the C2 hydrocarbon fed and to produce a product stream comprising vinyl chloride and hydrogen chloride; and (b) recycling unreacted hydrogen chloride back for use in Step (a). No C2 hydrocarbon recycle is required in this process. In another aspect, a process for producing vinyl chloride involving: (a) combining ethane, optionally ethylene, an oxygen source, and a chlorine source in a reactor containing a suitable catalyst under conditions sufficient to produce vinyl chloride and hydrogen chloride; (b) catalytically reacting said hydrogen chloride in a second reactor to provide a second reactor effluent essentially devoid of hydrogen chloride; and (c) recycling said second reactor effluent to step (a). Optionally, the second process may be run under conditions to react C2 hydrocarbons to extinction and thereby eliminate a need for C2 hydrocarbon recycle. Either process may include a hydrogenation unit for converting cis/trans-1,2-dichloroethylenes) to ethylene dichloride.

A transition metal carbide (e. g. , WC) is prepared by the following steps. A carbon-precursor mixture is formed by mixing a precursor comprised of (i) a transition metal oxide (e. g. , WO. sub. x) and (ii) a material selected from the group consisting of: a transition metal (e. g. , W); a transition metal carbide (e. g. , WC) and a substoichiometric carbide (W. sub. 2 C), in the presence of a source of carbon (e. g. , carbon black) in an amount sufficient to form a reduced mixture comprised of the transition metal carbide and substoichiometric transition metal carbide, wherein the amount of the transition metal oxide and transition metal is essentially zero in said reduced mixture. The carbon-precursor mixture is heated in a reducing atmosphere (e. g. , 5 percent hydrogen in argon) to a reducing temperature and for a time sufficient to produce the reduced mixture.

A process for preparing silicon carbide by carbothermal reduction which includes transporting, in a gaseous medium, a particulate reactive mixture of a silica source and a carbon source through a reaction zone. The heating rate of the atmosphere within the reaction zone is such that substantially all of the reactive mixture is heated at a heating rate of at least about 100. degree. C. /second until an elevated temperature of at least 1800. degree. C. is reached. Either (1) carbon monoxide is added to the reaction zone or (2) a carbon monoxide level in the reaction is achieved in order to provide at least about 30 mole percent of the gases exiting the reaction zone to achieve a higher yield of silicon carbide.
