NOVELTY - An unsaturated triglycerides is converted to bio-fuels by contacting modified triglyceride mixture with hot, compressed water having a catalyst for catalytic hydro-thermolysis; and post refining obtained crude hydrocarbon oil to produce various grades of bio-fuels.    USE - A process of converting unsaturated triglycerides to bio-fuels.    ADVANTAGE - The method has water that serves as a reactant, catalyst, and solvent for typical acid or base-catalyzed reactions, has hydrogen supply from water for hydrocarbon cracking as well as hydrolysis of triglycerides followed by decarboxylation, has high-pressure process that reduces the formation of gaseous products, and water that functions as a heat transfer medium that solves costly production and oil degradation during processing that will result in loss of valuable oil to gaseous by-products and less valuable coke.    DETAILED DESCRIPTION - An unsaturated triglycerides is converted to bio-fuels by preconditioning the unsaturated triglycerides to form a modified triglyceride mixture having a carbon backbone structurally altered by isomerization through catalytic conjugation resulting to conjugated triglycerides, cyclizing by combining the conjugated triglycerides with an alkene by Diels-Alder reaction, and cross-linking the fatty acid carbon backbones of the conjugated and cyclized triglycerides; contacting the modified triglyceride mixture with hot, compressed water containing a catalyst for catalytic hydro-thermolysis to produce a crude hydrocarbon oil; and post refining the crude hydrocarbon oil to produce various grades of bio-fuels. INDEPENDENT CLAIMS are included for:(I) a process of converting triglycerides to crude hydrocarbon oil;(II) a bio-fuel composition of formula CnH2n+m comprising 10-40% cyclo-paraffins derived from conversion of modified triglycerides, 0-10% aromatics derived from conversion of either triglycerides or petroleum or coal, and 50-80% paraffins derived from conversion of triglycerides.    m=0-2;and    n=10-12.    DESCRIPTION OF DRAWING(S) - The drawing is a flowchart showing the process of converting unsaturated triglycerides to bio-fuels.
