Abstract
Solid carbonaceous materials are pyrolyzed by feeding the carbonaceous material along with a particulate source of heat to a fast fluidized bed contained within a vertically disposed duct. An internally circulating stream of spent particulate source of heat and carbon containing solid residue of the pyrolysis of the carbonaceous material flows upwardly along the inner surface of the duct, thereby preventing carbonaceous material from caking on the duct.
