Abstract

Process for the conversion of synthesis gas to liquid hydrocarbon products by contacting, in a slurry reactor, synthesis gas at an elevated temperature and pressure with a suspension of catalyst in a liquid medium, introducing a low boiling solvent into the slurry reactor, vaporising at least a portion of the low boiling solvent in the slurry reactor, withdrawing from the slurry reactor, a gaseous stream comprising unreacted synthesis gas and vaporised low boiling solvent, cooling at least a portion of the gaseous stream to a temperature at which liquid condenses out so as to form a two phase mixture of gas and condensed liquid, and recycling at least a portion of the gas and at least a portion of the condensed liquid to the slurry reactor.
