A system for a Fischer-Tropsch synthesis using a three-phase reactor in which a primary filter removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter. Some or all portion of the product wax from the secondary filter can be recycled back to the reactor, either as a back flush medium for the primary filter or directly to the slurry in the reactor, whereby removal of catalyst fines is rendered independent of the rate of wax production.

Apparatus and method for conducting a fischer-tropsch synthesis reaction

A slurry bubble column reactor with a gas distribution arrangement comprising an upper sparger, a lower sparger, and an open-ended tube. Gas from the lower sparger enters the tube and lowers the density of slurry in the tube. The difference in slurry density causes the slurry in the tube to rise, causing slurry outside the tube to move down, maintaining circulation and flushing catalyst from the vessel wall.

Slurry bubble column reactor

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.
