A process for making diesel and turbine fuels includes providing an amount of one or more branched olefins and adding active heterogeneous acid catalyst(s) to the branched olefins to produce a mixture, which can be solvent-free. The process further includes heating the solvent-free mixture to a temperature greater than about 80°C for a sufficient time to produce a dimers/catalyst mixture, removing the catalysts from the dimers/catalyst mixture, and adding hydrogenation catalyst(s) to the dimers under hydrogen atmosphere to produce a mixture of stable fuels.

An effective method for producing high density fuel candidates from pinenes is provided. MMT-K10 is an efficient catalyst for the reaction, although significant amounts of p-cymene and camphene produced as byproducts limit the overall yield to about 80%. Nafion is also an excellent catalyst for pinene dimerization and was capable of producing dimers in up to 90% yield. Pinene dimers synthesized with these heterogenous catalysts have a density and net heat of combustion comparable to JP-10. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.

Hybrid antioxidants, phenols with a terpene and tert-butyl substituents, were synthesized by the alkylation of 2-tert-butyl-4-methylphenol with camphene and 2-isobornylphenol with tert-butyl chloride in the presence of acidic heterogeneous catalysts, montmorillonite KSF and FIBAN K-1. Antioxidant activity of the synthesized terpenophenols was evaluated using spectrophotometry.
