Abstract
A gaseous combustible fuel includes a gaseous hydrocarbon fuel feedstock and solid fuel particles suspended in the gaseous hydrocarbon fuel feedstock. The solid fuel particles have a sufficiently small particle size so that they remain suspended during transportation. The hydrocarbon fuel feedstock may include natural gas, ethane, propane, butane, and gaseous derivatives and mixtures thereof. The solid fuel particles may include coal-derived solid carbonaceous matter. Other examples of solid fuel particles include biomass, refined bioproducts, and combustible polymer particles. The gaseous combustible fuel has an energy density at atmospheric pressure which is at least 25% greater than the volumetric energy density of the gaseous hydrocarbon fuel feedstock. Improvements in volumetric energy density of 50%, 100%, and even 500% are disclosed. The gaseous combustible fuel may be pressurized to a pressure in the range from 2 to 100 atmospheres.
