Abstract
Process for the production of a synthesis gas for use in the production of chemical compounds from a hydrocarbon feed stock containing higher hydrocarbons comprising the steps of: (a) in a pre-reforming stage pre-reforming the feed stock with steam to a pre-reformed gas containing methane, hydrogen, carbon monoxide and carbon dioxide; and (b) cooling the pre-reformed gas to below its dewpoint and removing condensed water; and (c) reducing the amount of carbon dioxide the in the pre-reformed gas from step (b) to obtain a module of (H2−CO2)/(CO+CO2) of between 1.0 and 3.8 in the pre-reformed gas.
