Abstract: A process and apparatus are described for converting a feed that is substantially comprised of halogenated materials, and especially byproduct and waste chlorinated hydrocarbons as are produced from a variety of chemical manufacturing processes, to one or more higher value products via a partial oxidation reforming reaction step. These products can be in the form of a useful or salable acid product and/or a product synthesis gas comprised of carbon monoxide and hydrogen, or the reaction product including the same hydrogen halide, carbon monoxide and hydrogen components can be employed as a feed in the synthesis of a different useful or salable product.

Abstract: A powdered admixture of a boron, carbon, nitrogen or silicon derivative of a first metal is combined with at least one other reactant that is selected from (a) a boron, carbon, nitrogen or silicon derivative of a second metal wherein the derivative differs from that of the first metal, (b) a source of a second metal and a source of a third metal, or (c) a source of the second metal and a densification promoting amount of an iron group metal, subjected to densification conditions (heat and pressure), partially reacted and converted to a hard, wear resistant material. The wear resistant material contains an amount of the first metal derivative as well as at least one material of varying stoichiometry that is the partial reaction product. The material may also contains residual, unreacted portions of components other than the first metal derivative. Articles formed from this material can be useful in wear resistant applications.
