摘要: A coal liquefaction product is separated into an essentially solid free stream and a solid containing stream including the coal ash. The solid containing stream is hydrotreated, in the absence of added catalyst, and valuable clean fuel components stripped from the hydrotreated stream. The combustibles content of the stripped solid containing stream is reduced by hydrotreatment, prior to stripping.

摘要: A process for recovering the calcium values and sulfide values from a calcium sulfide-containing material is disclosed. The calcium sulfide-containing material dispersed in an aqueous medium is digested in the presence of hydrogen sulfide under conditions to provide a mole ratio of S.sup.-.sup.-/Ca.sup.+.sup.+ of between 1.5 and 2.0. After filtration to remove undissolved solids, the mother liquor is stripped with an inert gaseous medium, e.g. nitrogen, steam, etc., whereby hydrogen sulfide is stripped therefrom with the concomitant formation of calcium hydroxide which is subsequently separated by filtration. The gaseous overhead from the stripping operations may be fractionated to form a recycleable hydrogen sulfide-containing stream.

摘要: Olefin oxide is produced by reacting chlorine, obtained from an electrolysis cell, with a tertiary alkanol and an aqueous solution, containing sodium hydroxide and sodium chloride, obtained from the cathode of an electrolysis cell, to produce a tertiary alkyl hypochlorite. The hypochlorite is then reacted in a chlorohydrin reactor with an olefinically unsaturated compound and water, essentially free of chloride ions, to produce the corresponding chlorohydrin. The chlorohydrin is recovered and saponified with cell liquor, containing sodium hydroxide and sodium chloride, obtained from the cathode compartment of the cell to produce the olefin oxide.
