Abstract: Disclosed herein are methods and systems for upgrading (for example, removing heteroatoms, metals, or metalloids) an oil composition derived or extracted from a biomass. The upgraded oil composition can be used to make a desired product, for example, a fuel product.

Abstract: Algae oil feeds comprise a wide range of molecular species forming a complex mixture of molecules having varying sizes and therefore varying boiling points, comprise high nitrogen, oxygen, and fatty acid content, but comprise low sulfur, saturated hydrocarbons, and triglycerides. The wide range of molecular species in the algae oil feeds, very unusual compared to conventional refinery feedstocks and vegetable oils, may be upgraded into fuels by conventional refining approaches such as thermal and/or catalytic-hydroprocessing. Hydrotreating at high pressure over large-pore catalyst, and optionally followed by FCC cracking, has shown a beneficial product slate including coke yield. Thermal treatment prior to hydrotreating may improve hydrotreating feedstock quality.

Abstract: Crude algae oils are thermally-treated at temperature(s) in the range of 300-600° C., without catalyst and/or the addition of hydrogen, to produce a higher grade, cleaner algae oil with, for example, reduced oxygen, boiling range, viscosity and/or density, and acid number, in addition, because the thermal treatment reduces metals in the oil and produces carbonaceous solids, it is expected that catalyst deactivation by algae oil feedstocks will be greatly reduced if the crude algae oil or fractions thereof are thermally-treated prior to catalytic upgrading. Oxygen, fatty acids, metals, and metalloids are reduced/removed by the thermal treatment, so that RBI) processing of the crude bio-oil may be reduced or eliminated, and requirements for further deoxygenation and hydrotreating of the thermal products are reduced or eliminated.

Abstract: Renewable oils are converted to aromatics, by contact with a catalytically-active form of gallium, for use in the petrochemical industry and/or for fuel blending components or additives. The renewable oil(s) feature high oxygen content, high H/C mole ratios, and high fatty acid or fatty acid ester content prior to heating and contact with the catalyst. The catalyst may be, for example, a gallium-doped version of one or more zeolite-alumina matrix catalysts with pore sizes having 10 oxygen atoms in the pore mouth, such as ZSM-5, ZSM-11, ZSM-23, MCM-70, SSZ-44, SSZ-58, SSZ-35, and ZSM-22. Aromatics-production from the renewable oils is enhanced at higher gallium-cation levels, with the preferred level being about 1.0 Ga/framework-Al. While various renewable oils, or “bio-oils,” may be used, algae oil has exhibited very high BTEX yields over the gallium cation catalyst, under conditions at or near 1 atm and approximately 400 degrees C.

Abstract: In a hydrotreating process, a hydrocarbon feedstock having a boiling of at least about 460.degree. F. is contacted with a catalyst having at least one member selected from the group consisting of a carbide of a Group VIB metal and a nitride of a Group VIB metal under hydrotreating conditions.
