ABSTRACT:
A coal gasification process is disclosed wherein two portions of heat transfer material are introduced into the reaction vessel at different locations and different temperatures. Steam is passed upwardly through the vessel to react with the carbonaceous material to form a hot char and a gaseous product, wherein the heat necessary for the coal gasification reaction is supplied by both the first portion of heat transfer material and the second portion of heat transfer material. Then the hot char and gaseous product are cooled by contact with the first portion of heat transfer material.
