The physicochemical properties of all synthesised catalyst are investigated by X-ray diffraction, Brunauer�Emmett�Teller surface area, temperature-programmed desorption of carbon dioxide and scanning emission microscopy. The synthesised catalysts are tested on the basis of the deoxygenation (DO) reaction of waste cooking oil to produce liquid fuels under N2 atmosphere. The chemical composition of the liquid product is identified by gas chromatography�mass spectroscopy. The overall study suggests that Ni/CMD900 catalyst exhibits the highest performance with over 67.0% conversion and high selectivity (80.2%) with a high proportion of saturated linear hydrocarbons that corresponds to green diesel. Result indicates that Ni/CMD900 is a highly potential DO catalyst with 19.8% oxygenated compound, which is favourable for decarboxylation and/or decarboxylation predominates. � 2020 The Authors Final 2023-05-29T08:07:09Z 2023-05-29T08:07:09Z 2020 Article 10.1016/j.arabjc.2020.09.046 2-s2.0-85092695039 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85092695039&doi=10.1016%2fj.arabjc.2020.09.046&partnerID=40&md5=00543bd3753eda4b72defd4969141a35 https://irepository.uniten.edu.my/handle/123456789/25177 13 11 8146 8159 All Open Access, Gold Elsevier B.V.
