Synthesis, characterization and catalytic performances of activated carbon-doped transition metals during biofuel production from waste cooking oils

Abstract This study claimed for describing the synthesis and characterization of activated carbon doped transition metal (Mn, Fe) as effective and economic catalysts during catalytic cracking of waste cooking oil. The presented activated carbon was obtained from Peach crusts as economic, environmental and renewable resource. The prepared activated carbon and its transition metal doped forms were characterized using FTIR, XRD, thermogravimetric analysis, differential thermal analysis and N2-adsorption-desorption measurements. The physical and fuel properties of the obtained biofuels were approved compared to ASTM specifications. The performance of the different biofuel grades in engine tests was improved by blending regular diesel with 10% biofuel (BF10). The brake specific fuel consumption was decreased using BF10 blend. The brake thermal efficiency was also increased for BF10 from 16.21% to 27.25%. The brake specific fuel consumption was increased for BF10 blend compared to regular diesel.
