Synthesis and characterization of cao.Sio2 heterogenous catalyst derived from agricultural and natural waste for transesterification of waste cooking oil in biodiesel production / Jihan Fadila Hakim Binti Eko Budi Santoso Kuantan, Pahang : UMPSA, 2025 © 2025 xvi, 48 pages : illustrations ; rdacontent text rdamedia unmediated rdacarrier volume rda text file PDF Faculty of Industrial Sciences and Technology Final Year Report (Bachelor of Applied Science of Industrial Chemistry) -- Universiti Malaysia Pahang Al-Sultan Abdullah - 2025 Include bibliographical reference The objectives of this study to synthesise and characterise CaO.SiO2 catalyst from rice husk and seashell, and to prepare palm based-oil biodiesel from waste cooking oil by using heterogenous catalyst CaO.SiO2. Wet impregnation method was used to produce heterogenous catalyst. The catalyst are having 5 different composition, which are 10:0, 2.5:7.5. 5:5, 0:10 and 7.5:2.5 of calcium oxide: silica. The seashells and rice husk (source of calcium oxide and silica) were used for catalyst’s making. The effects of different ratio of both catalyst’s sources were studied. Transesterification method is a method in which an ester reacts with an alcohol to form a new ester and different alcohol, with the presence of catalyst. The goal is to convert triglycerides in waste cooking oil into fatty acid methyl esters and glycerol as byproducts. The conversion was suppose at least 60% of FAME’s production with 5:5 of CaO:SiO2 catalyst usage. However, the conversion was way far than the expected result though the biodiesel conversion was 81.71%. This situation is might due to the catalyst preparation.
