This patent describes a method of producing from coal a substantially nitrogen-free water gas by reacting coal with steam at water-gas reaction temperatures in a gas producer to form a hot water gas consisting predominantly of hydrogen and carbon monoxide. The process involves passing said hot water gas into contact with a mass of relatively cool, movable discrete heat-exchange solids in a solids preheating zone, and removing the resulting preheated solids to a solids heating zone and heating them to a temperature above the desired water-gas reaction temperatures by contact with hot products of combustion therein. The cooled water gas is separated into a plurality of streams with steam being added to one of said streams. The process continues by recycling it through a gas-heating zone and back to the gas producer for reaction with coal. The recycled gas is heated to water-gas reaction temperatures by introducing the hot heat-exchange solids into the path of said recycled gas in said gas-heating zone and removing the solids. These are recycled to the preheating zone, with a second stream of said cooled water gas being withdrawn as product gas from the process.
