摘要： Oil sands and similar hydrocarbon-solids mixtures are separated into their components by steps comprising: mixing with a solvent for the hydrocarbon in an extraction-contacting stage including a controlled light milling action, in the presence of hydrophilic bridging liquid, under selected conditions favoring the formation of large agglomerates of substantially all hydrophilic solids; controlling the milling action to break down continuously the agglomerates so that at equilibrium the agglomerate size is much smaller than expected; separating the agglomerates from the concentrated hydrocarbon solution and stripping solvent from this solution to leave hydrocarbon product; washing the agglomerates with solvent and recycling this dilute wash solution preferably to the extraction-contacting; desolventizing the agglomerates and recycling solvent preferably to the wash stage. The agglomerates have fast settling and draining properties and a low hydrocarbon content while the hydrocarbon product has a low solids content. An apparatus for carrying out this process is described.

摘要： Composite metal articles of high density are made from iron and lead or a lead-rich alloy in proportions suitably of about 25 to about 90 wt. % iron, when present up to about 5 wt. % of a lead alloy-forming element aiding wetting of the iron, and the balance substantially all lead. Preferably copper, zinc, tin, indium or mixtures thereof are present to aid wetting the iron phase.Composite bird shot, for instance, is prepared e.g. by matrix formation and infiltration, or by agglomeration techniques, or by other techniques, with, if desired, a final mechanical shaping or compaction. The presence of iron has been found to cause a significant reduction in toxicity to birds on ingestion.

摘要： The invention disclosed relates to a method for drying low-quality solid carbonaceous fuels such as lignite and sub-bituminous coal to reduce the moisture content substantially to zero, and to minimize re-adsorption of moisture during storage and transporation. The method involves drying the solid fuel in a mildly reducing atmosphere at a temperature in the range of 150.degree.to 300.degree. C., preferably 200.degree.to 210.degree. C. The mildly reducing atmosphere may be provided by a gaseous lower-alkane e.g. propane and methane. In some cases, the coal may beneficiated by agglomeration with small amounts of oil.
摘要翻译：所公开的本发明涉及一种干燥低质量固体碳质燃料如褐煤和次烟煤的方法，以将水分含量基本上降至零，并且在储存和运输期间使水分的再吸附最小化。该方法包括在温度在150℃至300℃，优选200℃至210℃的温和还原气氛中干燥固体燃料。可以通过气体低级烷烃例如低温烷烃来提供轻度还原气氛。丙烷和甲烷。在一些情况下，煤可以通过少量油的附聚来选矿。
