    • A method is provided for desulfurization of oil stock, e.g. residual oil, having a minimum sulfur content of about 2 weight percent and a minimum metals content of about 50 ppm to produce a low-sulfur, high-metals content raffinate and a high-sulfur, low-metals content extract which comprises contacting said oil stock with a solvent selective for low molecular weight aromatics and having a boiling point within the range of from about 0.degree. F to about 100.degree. F and a density greater than or less than the density of the oil stock being contacted by at least 0.1 g/cc, said contacting being conducted at a temperature of from about 60.degree. F to about 212.degree. F, a solvent/oil stock volume ratio of from about 0.25 to about 10 and a pressure higher than the vapor pressure of the solvent at the contacting temperature, and separating the low-sulfur, high-metals content raffinate from the high-sulfur, low-metals content extract.

    • A method is described for preparing a solid fuel in the form of a coal/liquid slurry for use in small furnaces. The fuel has a relatively uniform heating value of 10,000 to 14,000 Btu per pound and is prepared by crushing and grinding coal to less than 200 mesh, blending the coal fines with additives for SO.sub.x abatement, for ignition and oxidation promotion, and ash modifiers to improve the combustion quality of the fuel. The blended coal mixture is wetted with water and then slurried with oil, water or alcohol to form a thick slurry. The thick slurry is stabilized by proper selective of surfactants, polymers and other additives by way of interparticle bonding or bridging to provide a pumpable solid fuel that is stable in storage.
    • 描述了一种用于制备用于小型炉的煤/液体浆料形式的固体燃料的方法。 该燃料具有相对均匀的发热值10,000至14,000Btu /磅,通过将煤粉碎和研磨至小于200目,将煤粉与添加剂混合以进行SO x消除,用于点燃和氧化促进,以及灰分改进剂 燃料的燃烧质量。 混合的煤混合物用水润湿,然后用油,水或醇制浆,形成稠浆。 通过适当选择性的表面活性剂,聚合物和其它添加剂通过颗粒间粘合或桥接来稳定稠浆体,以提供在储存中稳定的可泵送固体燃料。
