Abstract: A process for producing at least one product from at least one gaseous reactant includes feeding the gaseous reactant, as a gaseous feed or as part of a gaseous feed which is at an inlet superficial gas velocity of at least 0.5 m/s, into a vessel holding an expanded slurry bed of solid catalyst particles suspended in a suspension liquid so that the gaseous reactant can bubble upwardly through the slurry bed. The slurry bed has a catalyst loading of at least 20% by volume of degassed slurry. The gaseous reactant is allowed to react catalytically at a pressure above atmospheric pressure as the gaseous reactant bubbles upwardly through the slurry bed to produce at least one product. The product and any unreacted gaseous reactant are withdrawn from the vessel.

Abstract: Method of operating a three-phase slurry reactor includes feeding at a low level at least one gaseous reactant into a vertically extending slurry body of solid particles suspended in a suspension liquid, the slurry body being contained in at least two vertically extending shafts housed within a common reactor shell, each shaft being divided into a plurality of vertically extending channels at least some of which are in slurry flow communication and the slurry body being present in at least some of the channels. The gaseous reactant is allowed to react as it passes upwardly through the slurry body present in at least some of the channels of the shafts, thereby to form a non-gaseous and/or a gaseous product. Gaseous product, if present, and/or unreacted gaseous reactant is allowed to disengage from the slurry body in a head space above the slurry body.

Abstract: A method of operating a three-phase slurry reactor includes feeding at a low level at least one gaseous reactant into a vertically extending slurry body of solid particles suspended in a suspension liquid, the slurry body being contained in a plurality of vertically extending horizontally spaced slurry channels inside a common reactor shell, the slurry channels being defined between vertically extending horizontally spaced divider walls or plates and each slurry channel having a height, width and breadth such that the height and breadth are much larger than the width.
