Abstract:

A method for producing a supercritical cryogenic fuel (SCCF) includes dissolving a hydrogen gas in fuel value proportions into a supercritical hydrocarbon fluid. The method is performed by placing a hydrogen gas and a hydrocarbon fluid at a pressure greater than the critical pressure of the hydrocarbon, placing the hydrogen gas and the hydrocarbon fluid at a temperature below or approximately equal to the critical temperature of the hydrocarbon forming the supercritical hydrocarbon fluid, and then mixing to dissolve the hydrogen gas into the supercritical hydrocarbon fluid. A system for performing the method includes a vortex mixer configured to turbulently mix the hydrogen gas and the supercritical hydrocarbon fluid. The supercritical cryogenic fuel (SCCF) produced by the method and the system includes the supercritical hydrocarbon fluid with a selected mole fraction of the hydrogen gas dissolved therein.
