Abstract: A gas distribution grid for a slurry reactor includes a plurality of gas injectors horizontally arrayed across, and extending through, an otherwise gas and liquid impervious plate. The injectors have a throat open at both ends, with a gas pressure reducing bore at one end which is the entrance end and with the other end opening into an upward opening cone. Flow diverting means in the injectors prevents slurry solids from entering the throat and being attrited by the high velocity gas jet exiting the bore into the throat. It is preferred that the gas injectors not protrude above the top surface of the grid and flat space is eliminated by means such as angular fillers, to prevent solids accumulation top of the grid. A chamfer may be present at the junction of the bore and throat to prevent unrestricted expansion of the gas jet entering the throat. This is useful for injecting gas into a reactive hydrocarbon synthesis slurry in a slurry reactor, with reduced catalyst attrition and deactivation.

Abstract: A process for the desulfurization, and reactivation of a sulfur deactivated catalyst constituted of cobalt composited with a titania support. The sulfur deactivated cobalt titania catalyst is first contacted with a gaseous stream of molecular oxygen at temperature sufficiently high to oxidize the sulfur component of the catalyst. The sulfur oxidized catalyst is next contacted with a liquid, preferably water, to remove the oxide, or oxides of the sulfur. The catalyst is then contacted with a reducing agent, suitably hydrogen, to restore the activity of the catalyst. During the treatment there is no substantial loss, if any, of cobalt from the catalyst.

Abstract: A process of enhancing both the activity and the methane selectivity of a Dispersed Active Metal (“DAM”) hydrogenation catalyst is disclosed wherein the DAM undergoes low temperature oxidation in a slurry phase to form an oxidized catalyst precursor that is unique in comparison to those formed by conventional high temperature deactivation processes. The oxidized catalyst precursor, which is stable, is subsequently reduced to form an enhanced catalyst by treatment with hydrogen-containing gas at elevated temperature. The process is useful in a wide variety of DAMs formed by art-recognized techniques. The process is equally applicable to the enhanced catalysts formed from the oxidized precursors and their use in hydrogenation reactions.
