Abstract
High sulfur content carbonaceous material, such as coal is desulfurized by continuous fluidized suspension (20) in a reactor (18) with chlorine gas, inert dechlorinating gas and hydrogen gas. A source of chlorine gas (30), a source (32) of inert gas and a source (34) of hydrogen gas are connected to the bottom inlet (24) through a manifold (28) and a heater (26). A flow controller (42) operates servos (36, 38, 40) in a manner to continuously and sequentially suspend coal in the three gases. The sulfur content is reduced at least 50% by the treatment.
