Abstract
Process of contacting a gaseous reactant stream comprising synthesis gas at elevated temperature and pressure with a suspension of a particulate Fischer-Tropsch catalyst comprising cobalt in a liquid medium in a reactor system comprising at least one high shear mixing zone and a reactor vessel, by a) contacting the particulate Fischer-Tropsch catalyst with a reducing gas at elevated temperature and pressure outside of the high shear mixing zone(s) and the reactor vessel and subsequently suspending the particulate Fischer-Tropsch catalyst in the liquid medium; b) passing the suspension from step a) through the high shear mixing zone(s) where the gaseous reactant stream comprising synthesis gas is mixed with the suspension; c) discharging a mixture comprising the synthesis gas and the suspension from the high shear mixing zone(s) into the reactor vessel; and d) converting the synthesis gas to liquid hydrocarbons in the reactor vessel to form a product suspension comprising the particulate Fischer-Tropsch catalyst suspended in the liquid medium and liquid hydrocarbons.
