Abstract:
Harvesting energy from biomass represents a sustainable approach to meet future energy demand as biomass is one of the largest renewable carbon sources. In Malaysia, aged oil palm trees are typically replanted after reaching 25-30 years old and oil palm trunks (OPT) can be abundantly collected from the replanting activities in palm oil plantations. This work evaluates bio-oil production through the co-pyrolysis of OPT and polypropylene (PP) with and without the use of catalysts. The addition of PP helps to concentrate the carbon content of bio-oil while the catalyst addition is expected to improve the desired composition of bio-oil. The proposed catalyst employed in this study was Ni-Mo/.Al2O3, which is mostly used in hydrotreatment for bio-oil upgrading due to its excellent thermal stability. However, its utilisation in the pyrolysis and co-pyrolysis of biomass has gained less attention. Thus, the feasibility of Ni-Mo/.Al2O3 to upgrade the bio-oil obtained from the co-pyrolysis of OPT and PP was investigated in this work. The maximum bio-oil yield was obtained at 600 °C and 700 °C from co-pyrolysis and catalytic co-pyrolysis, respectively. From the experiments, it is evidence that the addition of Ni-Mo/.Al2O3 resulted in improvement of hydrocarbon content in the bio-oil through the deoxygenation of the oxygenates and phenols.
