发明名称 INTEGRATED PROCESS FOR HANDLING SATURATED AND UNSATURATED CHLORINATED HYDROCARBONACEOUS WASTE AND BY-PRODUCTS FROM ALLYL CHLORIDE AND PROPYLENE OXIDE PROCESSES
摘要 A process for converting an unsaturated chlorinated hydrocarbon-containing stream which may further contain saturated chlorinated hydrocarbons to corresponding less-chlorinated hydrocarbonaceous products and hydrogen chloride, comprising (a) contacting the unsaturated chlorinated hydrocarbon-containing stream with hydrogen in the presence of a catalyst in a mild saturation reaction zone which is operated under conditions selected to saturate the unsaturated chlorinated hydrocarbons therein with a minimum of polymerization and coking, (b) contacting at least a portion of the effluent from the mild saturation reaction zone with hydrogen in the presence of a hydrodechlorination catalyst in a hydrodechlorination reaction zone to produce reaction products including a non-chlorinated olefinic product, hydrogen chloride and a less-chlorinated unsaturated hydrocarbon by-product fraction, (c) separating out and recovering non-chlorinated olefinic and hydrogen chloride products from the effluent from the hydrodechlorination reaction zone, and (d) recycling less-chlorinated unsaturated hydrocarbon by-product in said by-product fraction to the mild saturation reaction zone.
