Patent ID: 6953870

Claim:
A self-propelled liquid fuel composition for combustion in gaseous heater, comprising a. Preparing hydrocarbon mixtures of methane, ethane/ethylene, propane/propylene, butane/butene, pentane/pentene, hexane/hexene, heptane/heptene, and octane/octene, containing at least 1 wt % of ethane/ethylene as a propellant and at least 5 wt % of low value pentanes and heavier hydrocarbons, with vapor pressure equal or greater than 0 psig at ambient temperature in a container b. Pressurizing the hydrocarbon mixture to 150 psig higher to form liquid fuel c. Releasing the hydrocarbon mixtures at lower pressure to form gaseous fuel for combustion in heaters whereby a self-propelled liquid fuel for combustion in a gaseous heater is provided.
