Desulfurization of carbonaceous materials

Patent ·
OSTI ID:6518346
This invention relates to desulfurization of carbonaceous materials such as coal, coke and char. EPA standards for SO2 emissions generally necessitate the use of coals having sulfur contents of less than about 1 percent for industrial purposes, such as steam generation. It has now been found, according to the process of the invention, that excess sulfur may be effectively and economically removed from carbonaceous feed materials by treatment of the feed with a combination of hydrogen and hydrogen chloride gases at elevated temperature.
