Abstract
Ammonia synthesis gas is prepared by contacting coal with air and steam in a fluidized bed. Heat for the reaction is provided by downward flowing hot thermal refractory material through the fluidized bed. The refractory material is heated externally of the fluidized bed by combustion of fuel. Control of the ratio of steam and air to the coal provides a gasification product of approximately 3 moles carbon monoxide plus hydrogen per mole of nitrogen.
