Finding a more efficient method for the transesterification of triglycerides to biodiesel fuel (BD) is important in today s. ' World. In this study transesterification of, trilaurin was carried out in a solution containing 4wt% of the Lewis acid AlCl3. Dissolved in a cosolvent of ethanol and 5 MPa CO2. A conversion rate of over 90% was achieved within 1h at the low temperature. Of 180 ° C. The process indicates a co-catalytic effect of the Lewis acid and CO2. We postulate several key steps for the. Mechanism. First the CO2-ethanol, mixture enhances the, hydrogen bonding increasing the concentration of C2H5O < sup / >. Second. AlCl3 attacks the oxygen of COC to weaken the bonds to form carbonyl carbon OR1 which is, then easily attacked by C2H5O < sup / >. To give the transesterified product (C2H4COOR1). Third AlCl3 is, finally replaced by H to form glycerin (GL), and intermediates. Such as unmethyl esterified compounds (uME). AlCl3 was used as a flocculant and catalyst for converting waste cooking oil. (WCO) to BD. The process achieved 97% free fatty acid (FFA) conversion at 120 ° C, in 90min making it one of the most efficient. Systems available for WCO recovery. AlCl3 was also successfully applied to microalgae signaling the, potential for a process. That combines harvesting lipid, transterification, extraction and, to leading fully integrated microalgae-based BD, production.? Advertising 2015 Elsevier Ltd.
