ABSTRACT:
A method of treating off-gas from a Fischer-Tropsch reaction comprises recovering the off-gas and hydrogenating a portion of the olefins present in the off-gas and converting a portion of the carbon monoxide present in the off-gas to carbon dioxide or methane. The treated off-gas is then fed to a hydrogen manufacturing unit such as a steam reformer to form hydrogen that can be used elsewhere in the process.
