Abstract
This invention relates to a process for the removal of catalyst particles from a hydrocarbon stream () derived from the reaction of synthesis gas () with a particulate Fischer Tropsch catalyst in a Fischer Tropsch reactor (). The process includes a primary separation step () which makes use of a filter, wherein the filter has a pore size which is 70% to 95 of the average size of the particles of the Fischer Tropsch catalyst, thereby forming a primary filtered hydrocarbon stream () containing fine catalyst particles. The benefit of this selection of filter pore size is that it mitigates fines build-up on the filter of the primary separator. The primary filtered hydrocarbon stream () is then passed to a secondary separation step in a cross-flow filtration unit () which removes fine catalyst particles from the primary filtered hydrocarbon stream to provide a retenate () containing the catalyst fines, and permeate () containing a hydrocarbon product.
