1 Abstract

Gaseous, liguid and solid fuels are recovered from carbonaceous organic waste material by treating charges of waste material in several successive stages including preheating, drying and conversion into solid and gaseous phases, all as a result of heating in a common vessel or in two or three successive vessels. The solid phases are thereupon cooled prior to admission into a bin, either in a separate vessel or in the vessel for conversion into solid and gaseous phases. The gaseous phases are treated to separate oil from reaction water, combustible gases and inert gases. The charges are heated from without and are sealed from the atmosphere during all four stages of treatment. Each charge is mixed during heating and the intensity of mixing action, the heating action and/or the pressure in the vessel can be varied during one or more stages.
