Efficient conversion of pure and mixed terpene feedstocks to high density fuels

► Renewable, high-density fuels are synthesized from terpenes. ► Heterogeneous catalysts can be recycled several times without loss of activity. ► The properties of complex pinene dimer mixtures are heavily influenced by camphene. ► Alpha-pinene and camphene are synergistic partners in terpene dimerization. ► Ultra-performance fuels can be synthesized from crude turpentine.
