Abstract
Embodiments of a system and method are disclosed for obtaining high-energy fuels. In some embodiments, the system and method produces one or more fused cyclic compounds that can include one or more bridging points. The fused cyclic compounds are suitable for use as a high-energy fuels, and may be derived from biomass.
Claims11
A method, comprising:
- hydrogenating a carbonyl-containing precursor compound having a Formula I with a catalyst system and hydrogen gas to produce a mixture comprising an alcohol-containing compound having a Formula II;
- and
- converting the alcohol-containing compound to a diene-containing compound by dehydrating the alcohol-containing compound with a dehydrating agent to produce an alkene-containing compound and then pyrolyzing the alkene-containing compound to a diene-containing compound;
- wherein
- Formula I is
- wherein R is an oxygen-containing heteroaryl compound and R1 is hydrogen or alkyl;
- and
- Formula II is
- wherein R2 and R3 join together to provide an aliphatic ring.

A method, comprising;
- hydrogenating a carbonyl-containing precursor compound having a Formula I with a catalyst system and hydrogen gas to produce a mixture comprising an alcohol-containing compound having a Formula II;
- and
- converting the alcohol-containing compound to at least one fused cyclic compound comprising a bridged bicyclic skeleton by (i) dehydrating the alcohol-containing compound with a dehydrating agent to produce an alkene-containing compound and then pyrolyzing the alkene-containing compound to a diene-containing compound;
- and (ii) dimerizing the diene-containing compound to provide the at least one fused cyclic compound;
- wherein
- Formula I is
- wherein R is an oxygen-containing heteroaryl compound and R1 is hydrogen or alkyl;
- and
- Formula II is
- wherein R2 and R3 join together to provide an aliphatic ring.
