ABSTRACT:
A method for thermally flashing gases and liquids from a particle-form, normally solid carbonaceous material, including: contacting the carbonaceous material with a gas, which may supply at least part of the necessary heat, at essentially atmospheric pressure and a temperature and residence time sufficient to maximize the flashing of gases and liquids from the carbonaceous material but insufficient to decompose significant amounts of the flashed gases and liquids. Preferably, the carbonaceous material is entrained in the gas to form an entrained descending body of carbonaceous material in the contact zone. Residual solids containing carbonaceous material may be burned to produce fuel gas or reacted with steam or air and steam to form a synthesis gas and at least part of the flue gas or the synthesis gas utilized as the contact gas.
