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.

1. Apparatus for conducting a three-phase reaction, in which gaseous reactants are reacted in the presence of a finely divided solid catalyst in suspension in a liquid comprising, at least in part, the reaction product of the gaseous reactants, thereby forming a slurry, the apparatus comprising a reactor vessel, a primary filter unit, a filtrate cleaning unit, a degasser unit, and a filtrate buffer unit, and in which: the reactor vessel includes a reactant inlet and a gas outlet and is arranged to contain the slurry in use; the primary filter unit is arranged to be in contact with slurry in use, the primary filter unit having an outlet for primary filtrate; the filtrate cleaning unit is arranged to remove further particulate material from the filtrate in use, and includes an inlet for the filtrate, an outlet for liquid product that has been subjected to cleaning; the degasser unit is located between the primary filter unit and the filtrate cleaning unit; and the filtrate buffer unit is arranged to receive cleaned liquid product from the filtrate cleaning unit, the filtrate buffer unit having liquid product outlet, a liquid product recycle line from the filtrate buffer unit directly to the reactor vessel which conveys the liquid product from the filtrate buffer unit directly into the reactor vessel without passing through the primary filter unit, and an optional liquid product recycle line to the primary filter unit. 2. Apparatus as claimed in claim 1, further including a cleaned liquid product recycle line from the filtrate cleaning unit to the primary filter unit, whereby the primary filter can be back flushed using a portion of the liquid product. 3. Apparatus as claimed in claim 1, in which the primary filter is located within the reactor vessel. 4. Apparatus as claimed in claim 3, in which the primary filter is arranged, in use, to be at least partially immersed in the slurry. 5. Apparatus as claimed in claim 1, in which the filtrate cleaning unit is outside the reactor vessel. 6. Apparatus as claimed in claim 1, in which the filtrate cleaning unit is a secondary filter unit, the primary filter unit comprising a relatively coarse filter and the secondary filter unit comprising a relatively fine filter. 7. Apparatus as claimed in claim 1, in which the degasser unit includes a gas outlet, an outlet for filtrate leading to the filtrate cleaning unit, and an optional recycle line for filtrate leading back to the reactor vessel. 8. Apparatus as claimed in claim 1, further including a recycle line from the filtrate buffer unit to the filtrate cleaning unit. 9. A process for conducting a three phase reaction in the apparatus according to claim 1, in which gaseous reactants are reacted in the presence of a finely divided solid catalyst in a suspension in a liquid comprising, at least in part, the reaction product of the gaseous reactants, thereby forming a slurry, the process comprising the steps of: introducing the gaseous reactants into the slurry in the reactor vessel;subjecting the slurry to a filtration step to remove particulate material in the primary filter unit to produce a filtrate stream;subjecting the filtrate stream to a cleaning step in the filtrate cleaning unit thereby removing further particulate material to produce a liquid product stream to be received in the filtrate buffer unit; andrecycling at least a portion of the liquid product stream from the filtrate buffer unit to the reactor vessel by conveying the liquid product stream from the filtrate buffer unit directly into the reactor vessel without passing through the primary filter unit, and from the filtrate buffer unit to the filtrate cleaning unit. 10. A process as claimed in claim 9, including the further step of recycling at least a portion of the liquid product stream to the primary filter, thereby back flushing the primary filter. 11. A process as claimed in claim 10, in which the back flushing causes catalyst particles located on the primary filter to re-enter the slurry. 12. A process as claimed in claim 9, further including a fines removal step in which fine catalyst particles filtered out in the cleaning step are removed from the filtrate cleaning unit. 13. A process as claimed in claim 9, further including a degassing step in the degasser unit in which gas is separated from the filtrate stream from the primary filter unit and is removed from the process, while the remaining, liquid phase is directed to the filtrate cleaning unit. 14. A process as claimed in claim 13, in which a portion of the liquid phase from the degassing step is recycled to the reactor vessel. 15. A process as claimed in claim 9, for producing hydrocarbons in which the reaction is a Fischer-Tropsch synthesis reaction, carried out in the reactor vessel, wherein the reactor vessel comprises a slurry bubble column reactor, and in which H2 and CO are supplied to the slurry in the reactor, the slurry comprising the catalyst in suspension in the liquid including the reaction products of the H2 and CO, the catalyst being maintained in suspension in the slurry at least partly by the motion of the gas supplied to the slurry. 16. A process as claimed in claim 15, in which the reaction temperature is in the range 190-250° C. and/or the reaction pressure is in the range 10-60 bar. 17. A process as claimed in claim 15, in which a H2/CO ratio of the gases supplied to the Fischer-Tropsch synthesis reactor is in the range 1.1 to 2.2. 18. A process as claimed in claim 15, in which the superficial gas velocity in the reactor is in the range 5 to 60 cm/s. 19. A process as claimed in claim 15, in which the product of the Fischer-Tropsch synthesis reaction is subsequently subjected to post-processing. 20. A process as claimed in claim 19, in which the post-processing is selected from de-waxing, hydro-isomerisation, hydro-cracking and combinations of these.
