Abstract: The gas stream obtained from the pyrolysis of solid organic wastes and containing chlorine in the form of hydrogen chloride is processed to obtain a substantially chlorine free pyrolytic oil.The gas stream is first contacted with a hydrocarbon immiscible with the pyrolytic oils to quench the gas stream and reduce the gas stream temperature close to the dew point of water. This forms a two phase condensate of the quench hydrocarbon and pyrolytic oil. The phases are separated, the pyrolytic oil recovered and the hydrocarbon recycled as the quench. The resultant gas stream is then treated for removal of hydrogen chloride from the gas stream for disposal or recovery of hydrochloric acid.

Abstract: A process for the recovery of chemical values from waste solids, wherein shredded waste solids are intermixed with hot char and a carrier gas in turbulent flow and passed through a pyrolysis zone under turbulent conditions at a temperature ranging from about 300.degree. F. to about 2000.degree. F., with zone residence time of under 10 seconds, with subsequent segregation and recovery of volatilized organic chemical values, char and inorganic chemical values therefrom.

Abstract: A continuous process for converting particulate carbonaceous solids to gaseous hydrocarbons (from 1 to 7 carbon atoms per molecule of gas) by the rapid pyrolysis and in situ conversion of a portion of the pyrolysis product comprising heating a turbulent high velocity gaseous stream composed of carrier gas, carbonaceous solids and at least 2.0 weight percent water based upon the weight of carbonaceous solids and heating said stream in a pyrolysis zone at a temperature ranging from between about 1200.degree. F. to about 2400.degree. F. until at least a portion of said solids are converted to the desired gaseous hydrocarbons.
