Process for the production in continuous of hydrocarbons from synthesis gas in slurry reactors and for the separation from the solid phase of the liquid

摘要

Hydrocarbons are prepared, liquid at the reaction temperature, by feeding synthesis gas into three-phase turbulent reactors wherein the solid phase, consisting of the catalyst in particle form, is kept in suspension in the liquid phase by the rising synthesis gas. The reaction product is separated/filtrated in continuous from the catalyst dispersed therein, by means of a separation/filtration unit consisting of several filtration cartridges, each consisting of at least two porous filtering elements, the first having an average pore diameter ranging from 0.5 to 15 mum, whereas the second has an average pore diameter ranging from 0.002 to 0.1 mum.
