Abstract
A method for adjusting hydrogen to carbon monoxide ratio of syngas contaminated by sulfur impurities involving a water gas shift (WGS) reaction. In light of the presence of the sulfur impurities, the WGS can be implemented as a sour gas shift. WGS can provide good results by using a non-sulfided catalyst. Conditions can be employed which contribute to further enhanced CO-conversion in the reaction. The hydrocarbons or derivatives thereof obtainable from the method can further be refined and used for production of fuels or lubricants for combustion engines.
