Abstract: A tungsten-free hydrotreating catalyst is produced by contacting a refractory metal oxide support with an aqueous impregnating solution formed from an ammoniacal solution of nickel fluoride, preferably predissolved, and an Mo.sup.+VI oxide. The impregnating solution consists essentially of NH.sub.4.sup.+, Ni.sup.++, Mo.sup.+VI and F.sup.-, said Ni.sup.++ and F.sup.- being supplied from nickel fluoride and preferably contains nickel and fluoride ions in a ratio of substantially 1 to 2, and is used in an amount necessary for impregnating by the incipient wetness technique in a one-step impregnation.

Abstract: A coal solvation/liquefaction process wherein the coal is contacted with hydrogen and an octahydrophenanthrene-enriched solvent containing OHP and THP in a ratio of OHP/THP greater than 0.4, wherein the OHP is present in an amount of at least 5 percent by weight based upon the total weight of said solvent.The OHP-enriched solvent provides improved coal solvation and increases the production of distillate liquid (62) in a coal solvation/liquefaction (20, 24) process. The desired ratio of OHP/THP is provided by catalytic hydrogenation (68) of a coal liquid distillate stream (64). By increasing the OHP/THP ratio to a value greater than 1, the amount of hydrogen consumed in the process can be significantly reduced.

Abstract: Conversion of raw coal to distillate liquid and gaseous hydrocarbon products by solvent liquefaction in the presence of molecular hydrogen employing recycle of mineral residue is commonly performed at a higher thermal efficiency than conversion of coal to pipeline gas in a gasification process employing partial oxidation and methanation reactions. The prior art has disclosed a combination coal liquefaction-gasification plant employing recycle of mineral residue to the liquefaction zone wherein all the normally solid dissolved coal not converted to liquid or gaseous products in the liquefaction zone is passed to a gasification zone for conversion to hydrogen. In the prior art plant the amount of normally solid dissolved coal passed to the gasification zone is just sufficient to enable the gasification zone to produce the entire process hydrogen requirement.

Abstract: In the underground gasification of a swelling coal the high gas-flow link between the injection and the production wells needed for the gasification process is produced by reverse combustion using air heated to a temperature below the softening point of the coal. The heated air pretreats and conditions the coal proximate to the link under formation by increasing its permeability and reducing its swelling properties. Improved combustion and suppression of plugging results in the subsequent gasification stage.
