In this optimization study, iron-manganese doped zirconia-supported molybdenum oxide catalyst has been prepared and used in the synthesis of waste cooking oil based biodiesel by a simultaneous esterification and transesterification method. The catalyst is prepared via an impregnation method and consequently characterized by XRD, TEM, TGA (thermogravimetric analysis), TPD-NH3, and Brunauer-Emmer-Teller (BET) techniques. The simultaneous process for biodiesel production has been assessed and improved statistically via response surface methodology in combination with the central composite design. It has been established that the process for synthesis of waste cooking oil based biodiesel achieved about 96.8 biodiesel yield at a best condition of 200 °C, waste cooking oil/ methanol molar ratio of 1:30 and 5.0 wt. as loading of the catalyst. The highest ester yield of 96.8 has been obtained due to the improved physicochemical properties of zirconia-supported molybdenum oxide catalyst which accesses diffusion of the reactants to the active sites. © 2016 Author(s). date: 2016 publisher: American Institute of Physics Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84974559579&doi=10.1063%2f1.4953090&partnerID=40&md5=d430a8e23511493070450cf627a4f18e id_number: 10.1063/1.4953090 full_text_status: none publication: Journal of Renewable and Sustainable Energy volume: 8 number: 3 refereed: TRUE issn: 19417012 citation: Alhassan, F.H. and Rashid, U. and Taufiq-Yap, Y.H.
