Abstract:
A method of operating a slurry phase apparatus (10) includes feeding one or more gaseous reactants into a slurry body (37) of solid particulate material suspended in a suspension liquid contained inside a vessel (12). The one or more gaseous reactants are fed into the slurry body (37) through a gas distributor (14) having downward facing gas outlets (32) and are fed towards a fluid impermeable partition (18) spanning across the vessel (12) below the gas distributor (14). The partition (18) divides the vessel (12) into a slurry volume (19) above the partition (18) and a bottom volume (36) below the partition (18). A differential pressure is maintained over the partition (18) between predefined limits by manipulating or allowing changes in the pressure in the bottom volume (36) by employing a pressure transfer passage (34) establishing flow or pressure communication between the bottom volume (36) and a head space (40) above the slurry body (37).
Abstract:
The present invention relates to a reaction device for producing hydrocarbons from synthesis gas, and more specifically relates to a reaction device for producing hydrocarbons from synthesis gas, wherein hydrocarbons, olefins, oxygenates and the like are produced over a Fischer-Tropsch catalyst by using synthesis gas, in such a way that catalyst particles can easily be isolated from a slurry which is discharged to the outside. To elaborate, the object of the present invention is to provide a reaction device for producing hydrocarbons from synthesis gas, wherein an internal filter system for isolating enlarged particles in the form of an aggregate of the catalyst is provided inside the reactor, and an isolating device is disposed separately on the outside, such that it is possible to recirculate just particles of a size appropriate for performing F-T synthesis in the slurry phase, and, additionally, material such as fine catalyst particles or chipped-off catalyst produced during operation combine with substances such as liquid hydrocarbons and the resulting water in the slurry-phase reactor such that it is possible to effectively discharge and process the aggregated catalyst.
