Abstract
A process for the production of liquid hydrocarbon products by passing, at elevated temperature and pressure, synthesis gas and a fluidising liquid through a fluidised catalytic bed within a reaction zone, characterised in that the fluidised catalytic bed is an aggregative fluidised catalytic bed comprising a particulate Fischer-Tropsch catalyst having a density of greater than 4,000 kg/m3.

A process for the production of liquid hydrocarbon products by passing, at elevated temperature and pressure, synthesis gas and a fluidising liquid through a fluidised catalytic bed within a reaction zone, characterised in that the fluidised catalytic bed is an aggregative fluidised catalytic bed comprising a particulate Fischer-Tropsch catalyst having a density of greater than 4,000 kg/m3.
A process as claimed in any one of the preceding claims wherein the fluidising liquid is a high boiling hydrocarbon solvent having a boiling point, at standard pressure, of greater than 280° C.
A process as claimed in any one of the preceding claims wherein a low boiling solvent having a boiling point, at standard pressure, in the range of from 30 to 280° C. is introduced into the reaction zone.
A process as claimed in any one of the preceding claims wherein the aggregative fluidised bed is cooled within the reaction zone by means of heat transfer tubes positioned within the aggregative fluidised bed.
A process as claimed in any one of the preceding claims wherein the catalyst comprises iron or cobalt supported on a support.
