Patent ID: 8586365

Claim:
A method of optimizing the composition of a biofuel comprised of fatty acid alkyl esters, the method comprising: (a) submitting a sample of a fatty acid alkyl ester-containing component of the biofuel to an analyzer which measures the mass percentages in the component of at least two fatty acid alkyl esters; (b) inputting values indicative of the at least two fatty acid alkyl ester mass percentages into a processor which, in accordance with preprogrammed instructions, (1) calculates one or more fatty acid alkyl ester mass percentage ratios and algorithmically determines the volumetric percentages of one or more fatty acid alkyl esters in the component using the one or more fatty acid alkyl ester mass percentage ratios as algorithmic independent variables, and (2) correlates the one or more fatty acid alkyl ester volumetric percentages to fuel performance data and generates an output signal indicative of that correlation; and (c) controlling blending of the biofuel in response to the processor output signal.
