    • A method for destroying halocarbons. Halocarbon materials are reacted in a dehalogenation process wherein they are combined with a solvent in the presence of a catalyst. A hydrogen-containing solvent is preferred which functions as both a solvating agent and hydrogen donor. To augment the hydrogen donation capacity of the solvent if needed (or when non-hydrogen-containing solvents are used), a supplemental hydrogen donor composition may be employed. In operation, at least one of the temperature and pressure of the solvent is maintained near, at, or above a critical level. For example, the solvent may be in (1) a supercritical state; (2) a state where one of the temperature or pressure thereof is at or above critical; or (3) a state where at least one of the temperature and pressure thereof is near-critical. This system provides numerous benefits including improved reaction rates, efficiency, and versatility.
    • 一种破坏卤代烃的方法。 卤代烃材料在脱卤方法中反应,其中它们在催化剂存在下与溶剂组合。 优选含氢溶剂,其既用作溶剂化剂又可用作氢供体。 为了增加溶剂的氢气供应能力(如果需要的话)(或者当使用不含氢的溶剂时),可以使用补氢供体组合物。 在操作中,溶剂的温度和压力中的至少一个保持接近,等于或高于临界水平。 例如,溶剂可以是(1)超临界状态; (2)其温度或压力之一处于或超过临界状态; 或(3)至少其中一个温度和压力接近临界的状态。 该系统提供了许多好处,包括提高反应速率,效率和多功能性。
