| dc.description.abstract | Bio-oil derived from the thermal decomposition of waste biomass from oil palm fronds
has the potential to be utilized as an alternative energy raw material source. However,
its physical and chemical properties have weaknesses such as high oxygen to carbon
ratio, low selectivity of hydrocarbon components, and poor stability. Therefore, steps
are needed to enhance the quality of bio-oil to make it more compatible for storage
and further processing into liquid fuel. The combination with plastic waste containing
a high hydrogen to carbon ratio and a low oxygen to carbon ratio is one way to
improve the quality of bio-oil. This approach aims to produce a high yield of bio-oil
with more alkane and alkene components. The main objective of this research is to
enhance the production of bio-oil with a stable hydrocarbon component through
catalytic co-pyrolysis process at a temperature of 500°C, with N2 gas flow rate of
approximately 5 mL/sec for 1 hour, using oil palm frond waste and HDPE plastic
waste as feedstocks, employing zeolite mordenite catalyst impregnated with Fe and Co
metal oxides in a fixed-bed reactor system. The characteristics of the catalysts
obtained indicate that the metal impregnation process affects the configuration of the
mordenite zeolite. The success of incorporating metals into the zeolite is validated by
data from TEM and SEM-EDX analyses. The catalyst pores show the presence of
mesopores in each catalyst. CoO/MOR and Fe2O3/MOR catalysts resulted in an
increase in bio-oil yield percentage by 49% and 55.75%, respectively. GC-MS testing
results indicate that the MOR catalyst produces a significant amount of aromatic
hydrocarbons (10,08%). The CoO/MOR catalyst is effective in generating aliphatic
hydrocarbons in the diesel fraction (29,95%). The Fe2O3/MOR catalyst excels in the
production of cycloalkane aliphatic hydrocarbons (8%) and aliphatic hydrocarbons
in the gasoline fraction (36,81%). Additionally, the physical and chemical properties
of the bio-oil derived from both catalysts exhibit advantages, characterized by the
lowest oxygen content and highest heating value (HHV) among comparable co pyrolysis methodologies. | en_US |
