A method for producing products containing cyclic organic compounds from biomass oil includes adding a biomass oil to a vessel; heating the biomass oil to crack the biomass oil; removing undesired or unreacted materials, heavy ends, and light ends from the cracked biomass oil; and extracting components from the cracked biomass oil to produce a mixture of products containing between 5% and 90% cyclic organic compounds by weight. A method for producing a high-octane aviation fuel with low lead content includes cracking a biomass oil, separating a middle distillate mixture from cracked biomass oil, decarboxylating the middle distillate mixture to produce a mixture of products containing at least about 50% cyclic alkane and alkene compounds by weight, and blending the mixture of products with a fuel having an octane number below 95 to produce an aviation fuel having an octane number of at least 100.
