摘要： A hydrocarbon wax product from a hydrocarbon synthesis slurry comprising liquid synthesis product and catalyst particles is purified by introducing a portion of hydrocarbon synthesis slurry from a hydrocarbon synthesis zone to a treatment zone in which a treatment gas contacts the hydrocarbon synthesis slurry. Hydrogen or a hydrogen-containing gas is useful as the treatment gas. The gas treatment removes impurities from the hydrocarbon wax portion of the hydrocarbon synthesis slurry. Purified wax product is separated and removed in situ via wax withdrawal means. This avoids or minimizes the need for further treating the wax product.

摘要： Fresh catalyst particles are added to a slurry hydrocarbon synthesis reactor and their activity increased by contact with hydrogen in-situ in the slurry in a catalyst activity increasing means, while the reactor is producing hydrocarbons. The means may be a simple, vertically oriented and hollow tube, open at the top and bottom, into which slurry and a hydrogen treat gas are passed. The treat gas acts as a lift gas which provides slurry circulation into and out of the means and back into the slurry body, while increasing the activity of the catalyst particles. During the activity increase of the fresh catalyst, partially and reversibly activated catalyst particles are rejuvenated. The activity increasing means may be inside the reactor and at least partially immersed in the slurry or external of the reactor, or both.

摘要： The invention is a process for producing hydrocarbons from hydrogen and carbon monoxide by reacting hydrogen and carbon monoxide in the presence of a particulate solid catalyst and a substantially inert liquid medium. This reaction takes place in a reactor vessel adapted for the reaction of gases in the presence of a substantially inert liquid medium and a bed of solid particulate catalyst. The hydrogen gas and carbon monoxide gas are introduced at a plurality of locations within the reactor vessel. Bubbles of gas flow upward through the bed of solid catalyst particles and substantially inert liquid medium at sufficient velocity to expand the bed to a volume greater than its static volume. This velocity creates a turbulent reaction zone wherein liquid, gas, and solid catalyst are present and are in a state of motion.

摘要： The present invention relates to a process for carrying out an exothermic reaction in the presence of a solid catalyst in a three-phase slurry reactor (1) comprising a slurry zone (3) and a freeboard zone (5), in which slurry zone (3) the catalyst is kept in suspension in a slurry liquid, and in which freeboard zone (5) a liquid reflux is maintained to remove catalyst from the freeboard zone and, preferably, recycling the catalyst to the slurry zone (3). According to a further aspect, the present invention relates to a three-phase slurry reactor (1) adapted to the process, in particular a three-phase slurry reactor (1) wherein the freeboard zone (5) contains means to trap catalyst particles (10).

摘要： A gas distribution grid (106) for a slurry reactor includes a plurality of gas injectors (10) horizontally arrayed across, and extending through, an otherwise gas and liquid impervious plate (82). The injectors (10) have a throat (20) open at both ends, with a gas pressure reducing bore (14) at one end which is the entrance end and with the other end opening into an upward opening cone (30). Flow diverting means (26) in the injectors prevents slurry solids from entering the throat (20) and being attrited by the high velocity gas jet exiting the bore (14) into the throat (20). 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 (94), to prevent solids accumulation top of the grid. A chamfer (13) 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.
