Systems and methods are provided for the regeneration of adsorbent medium and the production of additional fatty acid esters, i.e., biofuel, in particular, by means of discharging adsorbed contaminants from an adsorbent medium such as an inorganic catalytic medium by methods that convert the contaminants into additional biofuel or biofuel intermediates, thereby increasing production efficiency, conserving labor, and reducing material waste and environmental contamination. |
