Abstract
The present invention is concerned with upgrading the BTU values of carbonaceous materials. The carbonaceous material is introduced into a heat exchanger and is injected with gas such as an inert gas or carbon dioxide at a high pressure to raise the pressure at which the upgrading process is carried out. The carbonaceous material is then heated to the desired temperature by circulating a heat exchange medium throughout at least one vessel which is in contact with the carbonaceous material. Water and other by-products such as tar and gases are recovered during this process. The heated water may be used as a source of pre-heating feed material in another vessel.
