NOVELTY - Oleaginous composition comprises oil extracted from biomass comprising a microorganism, where the composition is hydrotreated and the hydrotreated composition comprises: 30-90 wt.% carbon containing compounds comprising 8-18 carbons; 30-70 wt.% carbon containing compounds comprising 8-18 carbons; or 10-80 wt.% carbon containing compounds comprising 9-32 carbons, where wt.% is of the total amount of compounds detectable by mass spectrometry or gas chromatography analysis.    USE - The oleaginous composition is useful as hydrotreated effluent (claimed), which is useful for producing fuel or fuel blending components.    ADVANTAGE - The hydrotreated oleaginous composition has reduction in nitrogen of at least 75%, preferably 99%, or comprises less than 10 ppm, preferably less than 90 ppm of nitrogen, and contains low levels of sulfur and when compared to unhydrotreated composition. The thermal and/or catalytic-hydroprocessing of algae oil removes hetero-atoms, greatly reduces fatty acids, greatly increases saturated hydrocarbons, and cracks the algae feed to desirable liquid products that are good feedstocks for subsequent processes. The thermal treatment of whole crude algae oil mitigates catalyst deactivation and/or coke-on-catalyst production caused by the crude algae oil, thus extending catalyst life or improving heat balances in continuous catalyst regeneration systems.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) upgrading renewable oil obtained from biomass, comprising (a) providing the renewable oil, (b) dissolving at least a portion of the renewable oil in a solvent, and (c) upgrading the renewable oil in the solvent by a method comprising hydrotreating the renewable oil in the solvent in the presence of a catalyst at a temperature of 300-500 degrees C, a total pressure and/or hydrogen partial pressure of 800-3000 psi, a space velocity of 0.1-10 volume of oil per volume of catalyst per hour, and a hydrogen feed rate of 10-1700m3 H2/m3 dissolved oil, to obtain a hydrotreating effluent; and    (2) a hydrotreating effluent or hydrotreated effluent made by the above method.
