The effects of catalyst type, pyrolysis temperature, and biomass/catalyst ratio on product distribution and composition were studied. Among four catalysts tested, Na₂CO₃ significantly increased the selectivity of phenolic compounds in bio-oil during microwave pyrolysis. The highest phenolics concentration of 57.36% (area) was obtained at 500 °C and PT:Na₂CO₃ ratio of 8: 1. The catalytic effect to produce phenolic compounds among all the catalysts tested can be summarized in the order Na₂CO₃>Fe₃O₄>KOH>NaOH. Using KOH and NaOH as catalyst resulted in formation of bio-oil with enhanced higher heating value (HHV) and lower oxygen content, indicating that these catalysts enhanced the deoxygenation of bio-oil. The scanning-electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS) analysis of char particles showed the melting of magnetite and vaporizationcondensation of mineral salt catalysts on char particle, which was attributed to extremely high local temperatures during microwave heating.]]> Sat 24 Mar 2018 07:33:41 AEDT ]]> Desulfurization of coke oven gas using char-supported Fe-Zn-Mo catalysts: mechanisms and thermodynamics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27240 Sat 24 Mar 2018 07:29:12 AEDT ]]> Low-temperature catalytic hydrogen combustion over Pd-Cu / Al₂O₃ : Catalyst optimization and rate law determination https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50951 Mon 29 Jan 2024 18:24:44 AEDT ]]> Impact of pressure on the carbon structure of char during pyrolysis of bituminous coal in pressurized entrained-flow reactor https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42309 c), interlayer spacing (d₀₀₂) and lateral size of the graphite structures (L_a) were used to evaluate the graphitic structures in chars. The results showed an increase in L_c,, L_a, and the average number of graphene sheets with pyrolysis pressure, indicating a more ordered carbon structure at elevated pressures. The d-spacing of char was in the range of 3.34-3.37 Å, similar to typical graphitic structures.]]> Mon 22 Aug 2022 09:14:19 AEST ]]>
