Lewis, W K

This patent describes a process for preparing a fuel gas from solid carbonaceous material by reacting said carbonaceous material with a gasiform material which reacts endothermically to generate fuel gas rich in CO in a first reaction zone. The process involves reacting in a second zone of carbonaceous and gasiform material to form carbon dioxide. It continues by passing a moving stream of finely divided inert solids of high heat capacity in a closed cycle including said zones and feeding to said first zone off gases from said second zone. At least a portion of said off gases react endothermically with said carbonaceous material to form said fuel gas. You then feed partially spent carbonaceous material and inert solids from said first zone to said second zone and feed gasiform material capable of reacting exothermically with said partially spent carbonaceous material to said second zone in a manner such as to maintain the carbonaceous material and inert solids in said second zone in a fluidized condition. The process culminates by maintaining an exothermic reaction-producing carbon dioxide in said second zone, withdrawing a mixture of ash and hot inert solids from said second zone, separating ash from said hot inert solids, and returning at least a portion of said separated hot inert solids to said first zone.
