“…According to the GC-MS data, the thermal pyrolytic oil obtained herein contained 12.3% hydrocarbons, 20.23% phenols, 12.23% acids, 4.21% ketone, 8.26% ether, 2.1% furan derivatives, 5.56 % alcohol, 2.5% esters, 6.62% nitrogen-containing compounds, 5.2% aldehyde, and 3.3% amide groups. Similar results were also reported for the pyrolysis of pine wood and waste plastics (waste nitrile gloves (WNG) and polystyrene (PS)) (Mishra et al, 2022a) and groundnut shells (Kumar et al, 2021). When the primary goal is the application of pyrolytic oil as a transportation fuel, acids would be considered unfavorable, adversely affecting the fuel properties (Mohan et al, 2006).…”

The present work deals with an experimental investigation into the generation and characterization of pyrolytic oil and biochar from Sal wood sawdust (SW). The pyrolysis experiment was performed in a semi-batch reactor at 500 oC and 80 oC/min heating rate with CaO, CuO, and Al2O3 catalysts. Further, the pyrolytic oil and biochar were investigated using different analyses, including proximate analysis, elemental analysis, thermal stability, GC-MS, FTIR, field emission scanning electron microscopy, electrical conductivity analysis, higher heating value (HHV), zeta potential analysis, and ash content analysis. Pyrolysis results revealed that compared to thermal pyrolysis (46.02 wt%), the pyrolytic oil yield was improved by catalytic pyrolysis with CaO and CuO (50.02 and 48.23 wt%, respectively). Further, the characterization of pyrolytic oil revealed that the loading of catalysts considerably improved the oil's properties by lowering its viscosity (69.50 to 22 cSt), ash content (0.26 to 0.11 wt%), and oxygen content (28.32 to16.60 %) while raising its acidity (4.2 to 9.6), heating value (25.66 to 36.09 MJ/kg), and carbon content (61.79 to 74.28%). According to the FTIR analysis, the pyrolytic oil contained hydrocarbons, phenols, aromatics, alcohols, and oxygenated compounds. Additionally, the GC-MS analysis showed that catalysts significantly reduced oxygenated fractions, phenols (20.23 to 15.26%), acids (12.23 to 6.56%), and increased hydrocarbons (12 to 16 wt%). Additionally, the results of the biochar analysis demonstrated that SW biochar was appropriate for a range of industrial applications, including in catalysts, supercapacitors, fuel cells, and bio-composite materials.

“…16 In order to study the improved properties of pyrolysis gases, ZSM-5 is used at 20 wt % in this study. 17 The catalyst loading on SCB is optimized based on the available literature. Many authors also used the iso-conversational model to examine SCB kinetic modeling and thermal decay.…”

“…It has been discovered that ZSM‐5, a broadly used catalyst for biomass pyrolysis, significantly alters the configuration of bio‐oil by generating more organic matter (bio‐oil), which can be enhanced to gasoline and diesel, by significantly lowering oxygenated substances by deoxidization reactions, and by continuing to increase aromatic organisms 16 . In order to study the improved properties of pyrolysis gases, ZSM‐5 is used at 20 wt % in this study 17 . The catalyst loading on SCB is optimized based on the available literature.…”

This work deals with the characterization of feed, kinetic, and compositional study of sugarcane baggage (SCB) using a thermogravimetric analyzer (TGA), Py‐GC‐MS, and X‐ray fluorescence (XRF) analyzer. XRF analyzer was used to determine the mineral of ash content, and Py‐GC‐MS was employed to determine the hot vapor composition produced during fast pyrolysis. Cots‐Redfrem (CR) methods and master plots were utilized to determine the kinetic parameters. Studies on the physicochemical properties of SCB have demonstrated its potential for use as a bioenergy feedstock. The average activation energy was found to be 25.44 kJ mol−1 at (n = 1) and 31.21 kJ mol−1 at n ≠ 1 using the CR model. The master plot study suggested that pyrolysis occurred with various mechanisms, while kinetic results of SCB demonstrated that activation energy varied with conversion value. XRF examination revealed significant mineral materials that aided in the pyrolysis process. Finally, the introduction of ZSM‐5 at 20 wt % results increased hydrocarbons (~3 wt %), furfurelas (~4 wt %) and reduced the phenols (~15 wt %), acid (~9 wt %) and oxygnetaed compounds. The present study showed that introducing zeolite catalysts improved pyrolysis products' properties.
