NOVELTY - Production of high-quality jet propellant 8 (JP-8) or diesel fuel from triglyceride-rich biomass such as algae or oil seed comprises catalytically cracking triglycerides (105) in triglyceride-rich biomass-catalyst mixture, below 300 degrees C, to produce first bio-oil and cellulosic residue; catalytically cracking cellulose (110) in the cellulosic residue, at 300-600 degrees C, to produce second bio-oil; mildly hydrocracking (115) the second bio-oil, to produce hydrocracked portion; and isomerizing or alkylating (120) the hydrocracked portion.    USE - The method is for producing high-quality JP-8 or diesel fuel from triglyceride-rich biomass such as algae or oil seed (claimed). It is particularly useful for production of diesel fuel, jet fuel, and specialty chemicals from triglyceride-containing biomass including aquatic biomass. Fuels include light gases (ethane, propane, butane), naphtha, and distillates (heating oil). Chemicals include light olefins (ethylene, propylene, butylenes), acids (e.g. formic and acetic), aldehydes, alcohols (ethanol, propanol, butanol, phenols), ketones, and furans. The method is useful to any biomass including any amount of cellulose, hemicellulose, and/or lignin. Biomass includes microalgae (e.g. diatoms and green, blue-green, and golden algae), macroalgae (e.g. seaweed), other aquatic plants, and oil seed (soy, palm, rape, sunflower seed, peanut, cotton seed, palm kernel, olive, corn, nut, linseed, rice bran, safflower, sesame, and coconut).    ADVANTAGE - The method reduces equipment cost, energy cost, unwanted degradation of conversion products, and undesirable reactions of conversion products; increases the availability of fuel and/or specialty chemicals derived from triglyceride-containing biomass; and increases the value and utility of triglyceride-containing biomass feedstock for fuel and/or specialty chemical production. It has a synergistic effect, reducing the temperature necessary for catalytic conversion of the biomass and/or increasing the conversion efficiency of the biomass, as well as facilitating processing in conventional petroleum refining process units. The synergistic effect can include increasing the yield of organic compounds usable as fuel, feedstock, and/or specialty chemical, and/or reducing the yield of undesirable products such as tars and/or unconverted biomass in conventional petroleum refinery process units, converting different biomass components (e.g. cellulose, hemicellulose, and/or lignin) under milder conditions (e.g. lower temperature than conventional petroleum catalytic cracking) in conventional petroleum refinery process units, making the products of catalytic conversion more uniform, and increasing the selectivity or proportion of the production of desired products (e.g. increasing the proportion of a fraction usable as fuel, feedstock, or specialty chemical). The method does not require steam reforming and/or oligomerization steps to produce desired fuel or specialty chemical products because it does not require extensive breakdown and buildup to produce the desired hydrocarbon molecules; does not require a separate isomerization step because it can directly produce branched aliphatic hydrocarbon molecules; achieves higher conversion efficiencies than conventional petroleum methods; and can achieve conversion efficiencies of up to 55, preferably 100% with respect to triglycerides, cellulose, and/or overall biomass. The conversion efficiency for triglycerides is 85%. The conversion efficiency for cellulose is 85%. The overall efficiency is 72%.
