[ We claim:] [1.]1. An extended catalyst life process for producing liquid hydrocarbons from a synthesis gas, the process comprising:a) producing a synthesis gas comprising hydrogen and carbon monoxide by substoichiometric oxidation of a light hydrocarbon with an oxygen-containing stream comprising air or oxygen-enriched air;b) adjusting the hydrogen to carbon monoxide ratio in the synthesis gas to a range from about 1.0 to about 5.0;c) cooling the synthesis gas to a temperature below about 150.degree. F.;d) separating water from the synthesis gas;e) reducing the ammonia content of the synthesis gas to a value below about 10 ppmv by contacting the synthesis gas with an aqueous stream containing an acidic component; andf) reacting at least a portion of the reduced ammonia content synthesis gas in the presence of a catalyst comprising cobalt, ruthenium, or cobalt and ruthenium supported on an inorganic metal oxide support and a liquid comprising reaction product hydrocarbon liquids to produce liquid hydrocarbons.
