Abstract: 1,149,950. Coking; recovering hydrocarbon quench oils. BADISCHE ANILIN- & SODAFABRIK A.G. 31 Aug., 1966 [1 Sept., 1965], No. 38818/66. Heading C5E. Hydrocarbons and chlorinated hydrocarbons containing carbon black, e.g. obtained by washing hot gases, are recovered and particulate coke is produced from the carbon black by atomizing the hydrocarbons containing the carbon black and contacting the atomized material with a stream of hot gas to evaporate the hydrocarbons without cracking them. Hydrocarbons boiling in the range 140 to 350 C., e.g. propylbenzene, xylenes, naphthalene, and chloronaphthalene are mentioned and the hot gas stream should be free of oxygen, halogens and halohydrocarbons, examples being superheated steam, superheated hydrocarbon vapour, nitrogen, flue gas and cracked gas, and the maximum temperature is 800 C. A binder, e.g. resins, asphalt or bitumen, may be added to the mixture to be treated. The coke particles are separated from the gas/vapour stream and the hydrocarbons are recovered therefrom by conventional methods. Concurrent or counter-current contacting of the gas with the hydrocarbon may be employed, and in one embodiment (see Fig. 3, not shown), coking &c. is completed in a fluidized bed. The gas may be recycled after recovering the hydrocarbons therefrom. An example is described.
