Turpentine and other paper by-products make decent fuels, possibly separated as beta-pinene, alpha-pinene, carene, optionally saturated. But their big ring brings no or little heat of formation, loses two hydrogen atoms, and makes a stiffer molecule more prone to freeze. Due to C10, the flash point could be higher.
Maybe metathesis affords better molecules. Ethylene would make a C12, uneasily flammable. The flexible, open and very unsymmetric backbone should be harder to freeze. As is, it might be a (component of) jet fuel, or a Diesel fuel since the C3 chain eases autoignition. After saturation with hydrogen, it could be a rocket fuel, not magic but easily produced.
Beta-pinene, which has other uses, wouldn't fit as its double bond isn't in the ring. Carene I suppose neither because its big ring is unstrained. But alpha-pinene, otherwise little useful, has a double bond in its strained ring, which should help the metathesis.
The product has one very accessible double bond and may readily dimerize. I hope the strain in alpha-pinene lets the useful reaction outpace the unwanted one.
