1. A process comprising:
hydrotreating, hydrocracking, or both hydrotreating and hydrocracking an aromatic feedstock under conditions to obtain a liquid hydrocarbon fuel comprising less than about 30 ppm sulfur and less than about 13.5 wt. % hydrogen;
hydrogenating the liquid hydrocarbon fuel under conditions to obtain a hydrogen-rich fuel comprising less than about 1 ppm sulfur and greater than about 14.5 wt. % hydrogen;
transporting the hydrogen-rich fuel to a dehydrogenation facility;
dehydrogenating the hydrogen-rich fuel under conditions to obtain hydrogen and a second liquid hydrocarbon fuel comprising less than about 30 ppm sulfur and less than about 13.5 wt. % hydrogen;
separating the hydrogen and the second liquid hydrocarbon fuel; and
recycling the second liquid hydrocarbon fuel.
