Abstract
An improved process for the conversion of coal to low-sulfur products is disclosed wherein coal is heated with a liquid phase coal dissolution solvent, which is preferably a heavy aromatic petroleum solvent, in the presence of a solid, sulfur scavenger such as iron. Improved separation of inorganic solids, including both coal-derived and solvent-derived sulfur combined with the scavenger, is obtained by using a light cycle-oil modified slurry settler operation followed by separation. Vacuum distillation of the filtrate provides a low-sulfur solid which is used directly as fuel or coked to form low-sulfur distillates and coke. The scavenger is separated from other inorganics, regenerated, and recycled. Moderate amounts of fuel gas are also formed.
