(JP8027394-A)      Prodn. of carbon black comprises a) partially burning and gasifying organic wastes in a gaseous mixt. of an O2-contg. gas and steam with an equiv. ratio of O2 being 1 or less; b) partially burning the resulting combustible gas at 1000 C or above in an O2 deficient environment contg. less than a stoichiometric amt. of O2; and c) quenching the resulting partial combustion gas having a temp. of 1000 C or above to 700 C or below in an inert atmos.    Also claimed are (i) a process for the prodn. of carbon black with a first step of pyrolysing and gasifying organic wastes; (ii) a system for the prodn. of carbon black; (iii) a method for organic waste treatment comprising burning the waste in a gas mixt. having an O2 concn. of 10 to 21% and passing the exhaust gas over a heat exchanger to form steam some of which is used in the process; (iv) fixed bed gasification furnaces including a furnace divided into two sections, a volatiles pyrolysis section and a fixed carbon partial combustion/gasification section and including controlling the furnaces in response to organic waste layer height and temp.; and (v) methods of gasification of organic waste with controlled composition and feed rate of a gasifying agent.    USE -   In the combustion of organic wastes such as scrap tyres and waste plastics.    ADVANTAGE -   Carbon black can be produced from organic wastes in easily operated systems with high efficiency. Organic wastes can be burnt without producing soot or tar, without leaving any residual fixed carbon and without causing high temp. damage to the furnace. High molecular hydrocarbon gas containing aromatic compounds can be produced from organic waste. The fixed bed gasification furnace gasifying agents feed rates can be controlled to minimise fluctuation in temp. and maintain a stable pyrolysis temp. with variable organic waste feed rates.
