Supercritical methyl acetate (SCMA), glycerin-free process for converting total algal lipids into fatty acid methyl esters (FAMEs) and triacetin (TA). Triacetin (additive) is miscible with FAME and can be readily used as biodiesel fuel (BDF). Micro-elemental analysis (CHNOS) of total algal lipid and algal biodiesel fuel samples. Comparison of fuel properties of algal biodiesel fuel with regular diesel and ASTM biodiesel standards. Thermogravimetric analysis (TGA-DTA) of algal biodiesel fuel under nitrogen and oxygen environments.
