| dc.description.abstract | Compared to ZSM-5 and Al2O3, which are commonly used in the catalytic cracking of waste cooking oil (WCO), activated carbon showed higher liquid yield with more C9–C27 hydrocarbons. Due to bamboo possessing a higher surface area and porosity than wood-based activated carbon and charcoal, it performs better in catalytic cracking. Catalytic activity of activated carbon supported transition metal oxides (NiO, Fe3O4, CuO, CoO2, Al2O3 and ZnO) in catalytic cracking of WCO were studied in a batch reactor. The yield of the liquid product increased with the incorporation of metal oxides. AC supported Ni, Fe, and Zn oxides shown high selectivity towards C15 and C17 hydrocarbons in comparison to other catalysts in the study. The catalytic performance was compared with activated carbon supported bimetal oxide and trimetal oxide catalysts to examine their synergistic interaction. Trimetallic oxide catalyst often exhibit higher catalytic activity compared to monometallic and bimetallic oxide catalyst due to the synergistic effects between the different metals that could enhance the catalytic cracking. NiO-Fe3O4-ZnO/AC has a BET surface area of 835.85 m2/g with the strongest acidic sites of 20114 μmol/g. The catalytic activities also were studied in the temperature range of 340-400 °C, 30 – 120 minutes reaction and 1.0-6.0 g catalyst loading for the operating parameters study. The liquid product yield further improved to 93.17 wt% with 62.60% hydrocarbons yield and 94 vol% liquid product temperature range via NiO-Fe3O4-ZnO/AC at 400 °C, 1 hour reaction and 3.6 g catalyst loading. The influence of reaction temperature, reaction time and catalyst loading on its catalytic activity were tested. The catalysts can be used up to 5 cycles in the catalyst reusability test. | |
