    摘要: 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.

    摘要: A raffinate product of residual oil solvent extraction is upgraded in a fluid zeolite catalyst cracking operation in the presence of one or more low molecular weight carbon-hydrogen fragment contributors. Gas oil products of atmospheric and vacuum distillation may be simultaneously converted by admixture with the raffinate charge. In addition the process is enhanced by the addition of straight run naphtha product of distillation with the raffinate charge.
