In a process for forming a methane-enriched fuel, a hydrocarbon feedstock that includes hydrocarbons having molecular weights greater than that of methane (CH<SUB>4</SUB>) is mixed with an oxidizable gaseous reactant that includes water (H<SUB>2</SUB>O) and is free of molecular oxygen (O<SUB>2</SUB>). The mixture, which has a H<SUB>2</SUB>O/total hydrocarbon (H<SUB>2</SUB>O/C) ratio of less than about 1, is heated to an elevated temperature in the presence of a catalyst to form a methane-enriched pre-reformate product. At least a portion of the feedstock hydrocarbons having molecular weights greater than that of methane is converted to methane (CH<SUB>4</SUB>) in the process.
