Catalyzed production of different grade biofuels using metal ions modified activated carbon of cellulosic wastes

Abstract This work aims to convert waste cooking oil (WCO) into biofuel through a catalytic cracking process. The process of catalytic cracking was catalyzed using activated carbon loaded with iron and manganese ions. Cellulosic waste, as an eco-friendly, cheap, and renewable resource, was used to prepare the activated carbon. FTIR, XRD, TGA, differential thermal analysis, and N2-adsorption/desorption investigations were applied to characterize the prepared catalysts. Characterization of the obtained biofuels was established according to ASTM standard specifications. The engine tests of the different blends of biofuels-traditional diesel were performed. The obtained data confirmed that the biofuel blend contained 10% biofuel (B10) decreased the brake-specific fuel consumption from 651 g/kw.h for regular diesel to 554 g/kw, and raised the thermal brake efficiency from 15% to 17.4%. Therefore, a biofuel-petroleum fuel blend at 10% of biofuel can be presented as a promising fuel blend for the petroleum diesel.
