Gasification of Solid Carbonaceous Materials to Produce Gas Suitable for Ammonia Synthesis

摘要

Coal is contacted with air and steam in a fluidized bed and heat is provided by downward flowing hot char or hot thermal refractory material through the fluidized bed. The char or refractory material is heated externally of the fluidized bed by combustion of fuel and/or a portion of the char. 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.
