In this work, the performance of Ni-doped-calcined Malaysian dolomite (Ni/CMD900) catalyst with different catalyst synthesis techniques (precipitation, impregnation, and co-precipitation) were compared on the deoxygenation of waste cooking oil (WCO) process for green fuel production. The physicochemical properties of the synthesized catalyst were investigated by X-ray diffraction, Brunauer-Emmette-Teller surface area, temperature-programmed desorption of carbon dioxide, X-ray fluorescence, scanning emission microscopy and transmission electron microscopy analysis while the liquid products were analyzed by gas chromatography-mass spectroscopy and Fourier-transform infrared spectroscopy. Evidently from the result of the observation, the preparation technique plays an important role in determining the physicochemical properties of the catalyst for deoxygenation reaction of WCO in which precipitation technique outperformed other methods. Synthesized Ni-Malaysian dolomite-based catalyst, PRE/Ni/CMD900 catalyst was found to be superior in deoxygenation reaction activity as compared to other catalysts with high conversion of WCO (68.0%), high yield of pyrolysis oil (36.4%), and less coke formation (32.0%). � 2021 Final 2023-05-29T09:05:39Z 2023-05-29T09:05:39Z 2021 Article 10.1016/j.renene.2021.06.074 2-s2.0-85108421846 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85108421846&doi=10.1016%2fj.renene.2021.06.074&partnerID=40&md5=017d4b70cb8f022c1a82eb4286c1a236 https://irepository.uniten.edu.my/handle/123456789/25938 178 128 143 All Open Access, Green Elsevier Ltd Scopus |
