Abstract

A process for hot or supercritical water oxidative decomposition of wastes, particularly halogenated organic compounds, is described. The process employs a heterogeneous reagent which accelerates the decomposition and is effective to neutralize acidic byproducts. The reagent is maintained in suspension throughout the reaction by operating at conditions of temperature and pressure at which the heterogeneous reagent is largely or fully insoluble in water, and preferably at which liquid water is not present. Production of potentially corrosive brine is also minimized by operating at conditions under which sodium chloride is insoluble.
