NOVELTY - Manufacture of bio-diesel oils containing alkane compounds, comprises hydro-deoxidizing carbon oxide compounds to produce single-carbon alkane and temporarily active free radical of single-carbon alkane; reforming single-carbon alkane and temporarily active radical to make synthetic alkylation matter containing 3-25C; esterifying fatty acid with alcohol to alkyl fatty ester; and mixing synthetic alkylation matter and alkyl fatty ester.    USE - The method is for manufacturing bio-diesel oils containing alkane compound (claimed). The bio-diesel oil is usually cataloged into two types, thermal bio-diesel oil and power bio-diesel oil. The thermal bio-diesel oil is formulated for use in boilers, and the power bio-diesel oil is formulated for use in vehicles and diesel engines.    ADVANTAGE - The bio-diesel oil contains no sulfur or aromatic hydrocarbon and has excellent lubricant efficiency. The bio-diesel oil decreases multiple contaminating indexes such as carbon monoxide, hydrocarbon compounds, particle matter, and nitrous oxide to cause less pollution than the conventional mineral diesel oil.    DETAILED DESCRIPTION - Manufacture of bio-diesel oils containing alkane compounds, comprises:    (1) obtaining carbon oxide compounds;    (2) hydro-deoxidizing the carbon oxide compounds to produce single-carbon alkane and a temporarily active free radical of the single-carbon alkane (-CH2-);    (3) reforming the single-carbon alkane and the temporarily active radical of the single-carbon alkane to make a synthetic alkylation matter containing 3-25C;    (4) obtaining fatty acid;    (5) esterifying the fatty acid with alcohol to alkyl fatty ester; and    (6) mixing the synthetic alkylation matter and the alkyl fatty ester.    An INDEPENDENT CLAIM is also included for a bio-diesel oil, comprising synthetic alkylation matter containing 3-25C intermediate alkanes, which is obtained from reforming single carbon alkane; and alkyl fatty ester.    DESCRIPTION OF DRAWING(S) - The figure is an operational flow chart of a hydro-deoxygenation process for manufacture of bio-diesel oils containing alkane compounds.
