Temperature Effect on the Characterization of Pyrolysis Products from Oil Palm Fronds
並列摘要
The oil palm fronds (OPF) have the great potential in satisfying the energy demand due to its abundant availability. Due to limited usage and commercialization, lack of research work attempted on the OPF as compared with other oil palm wastes. Thermal conversion process, pyrolysis was performed on the OPF in the range between of 300‐500℃ for two hours at a constant heating rate of 10℃/min. The setup of fixed bed reactor and liquid collecting system was build up to collect and determine the yield of bio‐char, pyrolysis oil and gases. The maximum yield of OPF bio‐char was obtained at 300℃ with 50.95 wt% meanwhile, pyrolysis oil yield was observed to be initially increased until the maximum yield was reached at 400℃ with 47.41 wt%, and then decreased with the increment of temperature from 400‐500℃. The bio‐char obtained from this work consisted of high amount of HHV within the range of 18.80 to 19.40 MJ/kg, but contained high ash content with the maximum around 4.52 mf wt% after pyrolyzed at 500℃. Pyrolysis oils were found to be more acidic, higher ash content and decrement of HHV as temperature increased; furthermore, they were separated into two phases, tarry and an aqueous fraction.
