摘要： A process (10) to produce Fischer-Tropsch products includes feeding feed synthesis gas (30) with a substantially constant target feed synthesis gas H2/CO ratio to a Fischer-Tropsch synthesis stage (16). A portion of the feed synthesis gas (30) is converted to Fischer-Tropsch products in the Fischer-Tropsch synthesis stage (16). The Fischer-Tropsch products (20) from the Fischer-Tropsch synthesis stage (16) are withdrawn. A Fischer-Tropsch synthesis stage tail gas (26) which includes unconverted H2 and CO is obtained. The operating conditions of the Fischer-Tropsch synthesis stage (16) are manipulated to achieve a substantially constant target tail gas H2/CO ratio, with the target tail gas H2/CO ratio being substantially different from the target feed synthesis gas H2/CO ratio.

摘要： A method of operating a slurry phase apparatus includes feeding one or more gaseous reactants into a slurry body of solid particulate material suspended in a suspension liquid contained inside a vessel. The one or more gaseous reactants are fed into the slurry body through a gas distributor having downward facing gas outlets and are fed towards a fluid impermeable partition spanning across the vessel below the gas distributor. The partition divides the vessel into a slurry volume above the partition and a bottom volume below the partition. A differential pressure is maintained over the partition between predefined limits by manipulating or allowing changes in the pressure in the bottom volume by employing a pressure transfer passage establishing flow or pressure communication between the bottom volume and a head space above the slurry body.
