, a freezing point of not higher than −50° C., and a net mass heat value of not less than 42.0 MJ/kg; the process for preparing a fused-ring alkane fuel, wherein the process includes steps of: (1) in a presence of ultraviolet light and a photocatalyst, a Diels-Alder cycloaddition reaction between a substituted or unsubstituted cyclic enone and a substituted or unsubstituted furan molecule occurs to produce a fuel precursor molecule:
(2) the fuel precursor molecule obtained in the step (1) is subjected to hydrodeoxygenation to produce the fused-ring alkane fuel.
