  • Liquid phase process for converting synthesis gas
    Patent number: 5786393
    Abstract: In the synthesis of essentially linear saturated C.sub.5.sup.+ hydrocarbons from synthesis gas, the reactive gas phase circulating either as a downflow or as an upflow through a fixed bed catalytic reaction zone, an upflow of an inert liquid phase through said zone at a superficial flow rate of more than 0.01 cm/s, as compared to a downflow of liquid phase, increases the selectivity of the process to the formation of the desired C.sub.5.sup.+ cut.
