    摘要： A general method for producing low-sulfur gas and solid fuel is disclosed. Such method involves partial gasification of coal, using steam and an oxygen-containing gas, to produce low-B.t.u. fuel which can be used as a feedstock for power plants and industrial boilers. Also disclosed is a method for simultaneously producing low-sulfur gas, liquid, and solid fuels from coal in a single reaction vessel using a multi-stage fluidized gasification and desulfurization system. Synthesis gas produced in a first stage gas generator by reaction of steam, an oxygen-containing gas, and auxiliary carbonaceous fuel, is reacted with high-sulfur coal in a second stage desulfurization unit forming a solid phase consisting of low-sulfur fuel and a fluid phase consisting of sulfur-containing gaseous and liquid fuels. After disengagement of solid and fluid phases present in the second stage reaction zone, a solid fuel of reduced sulfur content is recovered.

    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 stabilized lubricating oil stock resistant to oxidation and sludge formation upon exposure to a highly oxidative environment is formed by contacting the lubricating oil stock with hydrogen in the presence of a catalyst of low acidity comprised of a platinum-group metal on a solid refractory inorganic oxide support.A benefit of the present treatment process is that a high sulfur lubricating oil stock can be converted hereby into a stock which can be formulated using an additive package not containing a zinc-based component.
