Abstract The need to increase bio-oil yield from biomass and enhance its fuel properties has driven research into optimizing the pyrolysis process. This study investigated influence of three key process parameters—temperature, heating rate, nitrogen flow rate—on elephant grass (Pennisetum purpureum) in a fixed-bed reactor. Response surface methodology was used impact aforementioned variables on improve production efficiency. Proximate analysis revealed 79.24 wt% volatile matter, 14.22 fixed carbon, 5.86% ash, with ultimate showing 45.44% 5.59% hydrogen, 40.95% oxygen. high matter content favourable carbon hydrogen percentages indicate that is viable energy source due potential for content. resulting exhibited higher value 20.9 MJ/kg, indicating suitability various applications. A second-order regression model developed yield, optimal conditions identified as temperature 550°C, rate 17°C/min, 6 ml/min. achieved an 59.03 wt%, model’s R² 0.8683 variance confirmed predictive accuracy. highlights sustainable feedstock production, offering valuable insights thus advancing biofuel technology.

The dependence on fossil fuels and the overexploitation of it is a bottlenecked problem globe leading to finding alternative renewable resources that may be used as an energy source in place fuels. Thermogravimetric analysis (TGA) technique identify potential sources. This study investigated kinetic, thermodynamic parameters, pyrolysis characteristics sesame stalk (SS) biomass using thermogravimetric (%) (TG)‐derivative thermogravimetry (DTG) techniques. was carried out at different heating rates (15, 20, 25°C/min). chemical kinetics parameters were determined isoconversional model‐free methods, including Kissinger–Akahira–Sunose (KAS), Ozawa–Flynn–Wall (OFW), model fitting techniques like Coats–Redfern (CR) model. (∆ H , ∆ G S ) calculated kinetic data. average activation for SS found 77.96 84.15 kJ/mole KAS OFW respectively. ( E from integral method varied between 29.61–142.58 reaction order models 4.90–122.33 diffusion models. distributions pre‐exponential factor A are virtually normal range 0.2–0.7, upon Eα values obtained approach. value enthalpy, Gibbs free energy, entropy also reported. suggests SSs sustainable bioenergy production, data crucial reactor design SSs.
