A retort is described in which solid carbonaceous materials, such as oil shales, can be processed and upgraded to liquid or gaseous hydrocarbon fuels. The solid particles fall by gravity through baffles into preheat, pretreatment, reaction, heat addition, and gas preheat zones. Gas passes through the reactor countercurrent to the solids. When hydrogen is used as the upflowing gas, the product stream comprises principally hydrocarbon liquids and low molecular weight paraffinic gases. Using air, oxygen, steam, flue gases, or mixtures of these, the product stream will also contain steam, carbon dioxide, carbon monoxide, and nitrogen. A rapid heat-up of 4000 F per minute to a temperature of 899 F results in high total carbon conversions.
