TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The catalyst is alumina, silica-alumina, sulfated metal oxides, zeolites, palladium, niobium, molybdenum, platinum, titanium, aluminum, cobalt and/or gold.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: A functional group is added to the cracked biomass oil, and decarboxylation, alkylation and/or hydrogenation is performed. The extraction process is solvent extraction, distillation, evaporation, membrane separation and/or chemical reaction. The biomass oil is heated at 300-700 degrees C for 5-500 minutes. The biomass oil is heated in presence of inert gas, nitrogen, water vapor, hydrogen, and/or mixture of vapor-phase organic chemicals. A catalyst is further added to the reactor vessel before heating the biomass oil. The reactor vessel is batch-type reactor vessel, continuous flow through-type reactor vessel, slurry-type reactor vessel, flow through packed bed-type reactor vessel, and fluidized bed-type reactor vessel. The cyclic organic compounds are blend with a primary fuel stream having primary octane number to produce a fuel product having an octane number higher than the primary octane number by more than 2 octane units. The obtained fuel product is aviation gasoline having octane number of 100 and lead content of less than 0.56 g/liter. The cyclic organic compounds are blended with primary fuel stream chosen from kerosene, biodiesel, processed biomass stream, or fuel blendstock to produce fuel product based on ASTM D 910-04a. Preferred Composition: The cyclic organic compound is aromatic and cycloparaffin compound. The mixture of chemical products contains preferably 20 wt.% or more of cyclic organic compounds, more preferably 30 wt.% or more of cyclic organic compounds, most preferably 50 wt.% or more of cyclic organic compounds. The biomass oil is chosen from plant oil, biologically generated lipid and/or animal fat. The plant oil is chosen from soybean oil, canola oil, palm oil, sunflower oil, corn oil, flaxseed oil, jatropha oil, jojoba oil, cottonseed oil, safflower oil, crambe oil, evening primrose oil, sesame oil, rapeseed oil, olive oil, coconut oil and/or camelina oil. The cyclic organic compound comprises 50 wt.% or more of toluene and/or benzene. The primary fuel stream is alkylate, aviation gasoline blendstock, finished aviation gasoline product, motor gasoline blendstock and/or finished motor gasoline product. The cyclic organic compounds are purified to obtain a product. The product is chosen from benzene, toluene, cumene, xylene, and ethyl benzene. The cyclic organic compounds are processed to remove solvents, or purify the cyclic organic compounds. The fuel product has chemical composition which enables the fuel product as substitute or blendstock in United States military fuels JP-8, JP-4 or JP-5 or commercial aviation turbine fuel based on ASTM D 1655-09.
