The disclosure deals with a slurry bubble column reactor for converting a gas mixture comprising carbon monoxide and hydrogen into liquid hydrocarbons. The slurry bubble column reactor features a slurry bed of catalyst particles, an inlet conduit for feeding the gas mixture into the slurry bed, a filtration zone for separating the liquid hydrocarbons from the catalyst particles and a liquid outlet conduit for withdrawing the separated hydrocarbons from the filtration zone. The filtration zone is situated in the slurry bubble column reactor such that the slurry bed is found in a first and a second heat exchange zone with the filtration zone arranged between the first and the second heat exchange zone.

Slurry bubble column reactor for a fischer-tropsch process

A system and process for removing catalyst fines from a gas stream overhead the slurry in a Fischer-Tropsch slurry bubble column reactor. The gas phase at the top of the slurry bubble column reactor containing small amounts of entrained liquid and catalyst particles. The unreacted gases are passed through a demister, which removes larger droplets and catalyst particles. Smaller droplets and catalyst fines are conveyed to a secondary gas cleaner, such as a cyclone, whereby substantially all remaining particles are removed from the gas phase. A particle-containing liquid produced in the secondary gas cleaner can be further subjected to a filtrate cleaning unit to filter out fine catalyst particles and produce a substantially particle-free liquid product stream and a slurry stream of liquid product containing catalyst particles.

Apparatus and process for three-phase reaction

The invention provides a method for the protection of internal filters of a LTFT slurry bubble reactor. The method includes the step of activating an emergency back-flush procedure during low slurry level conditions and/or during increasing temperature of an internal filter.

Method and system for the protection of internal filters of a LTFT slurry bubble reactor

The invention provides a method for the separation of liquid from a three phase slurry bubble column. The method includes the step of charging the inside of a hollow filter element with a rinsing fluid to clean the inside of the filter for catalyst fines followed by a backflushing step. The invention also provides an installation for the separation of liquid from a three phase slurry bubble column. The installation includes at feast one hollow and enclosed filter element and one or more conduits in fluid communication with the internal volume of the filter, with at least one conduit being configured or connected for inflow of rinsing fluid and at least one conduit being configured or connection for outflow of rinsing fluid.
