Abstract: Liquid hydrocarbons are capable of forming solutions of methane which is substantially soluble for example in liquefied petroleum gas creating a potential for the production of liquid fuel solutions of methane and liquefied petroleum for storage, industrial use and vehicular fuel. A binary mixture of hydrocarbons, comprised of methane dissolved in propane or butane is presented which enhance the amount of methane soluble in propane and butane thereby providing a product and methodology for establishing natural gas as an alternative fuel. A binary liquid fuel solution of methane is provided by directly mixing a liquefied petroleum gas into liquefied natural gas thereby cooling the liquefied petroleum gas in order to dissolve an enhanced amount of methane into the liquid by contacting the cooled liquefied petroleum gas/liquefied natural gas liquid blend with dried pipeline natural gas or other sources of natural gas.
