Selective production of C5-C40 hydrocarbons containing C5-C20 hydrocarbons having a high paraffins content, i.e., for producing gasoline and diesel fuel and useful as a chemical feedstock, is achieved by contacting H2/CO mixtures with supported ruthenium catalysts under conditions including elevated temperature and ratios of gas hourly space velocity/pressure below about 24,000 v/v/hr/MPaA to effect percent CO conversions at least about 20%. The ruthenium catalyst support contains a titanium oxide, niobium oxide, vanadium oxide or tantalum oxide and C5-C40 hydrocarbons can be selectively obtained in about 60-90 weight percent of total hydrocarbon products.
