Determination of Kinetic and Thermodynamic Parameters of Pyrolysis of Coal and Sugarcane Bagasse Blends Pretreated by Ionic Liquid: A Step towards Optimization of Energy Systems

Pyrolysis behavior of ionic liquid (IL) pretreated coal and sugarcane bagasse (SCB) blends through thermogravimetric analysis (TGA) was studied. Three SCB having 3:1, 1:1, 1:3 ratios by weight were treated with 1-ethyl-3-methylimidazolium chloride ([Emim][Cl]) at 150 °C for 3 h. Untreated IL then analyzed under pyrolytic conditions in a TGA constant ramp rate 20 °C/min. Kinetic thermodynamic parameters evaluated using ten Coats-Redfern (CR) models to assess reaction mechanism. Results showed that the untreated followed definite pattern proportional concentration blends. exhibited higher average degradation total loss, indicating had disrupted cross-linking structure lignocellulosic SCB. This will enhance energy generation potential biomass thermochemical conversion processes. The lower activation (Ea) calculated blends, revealing facile thermal decomposition after treatment. Thermodynamic parameters, enthalpy change (ΔH), Gibbs free (ΔG), entropy (ΔS), revealed pyrolysis reactions endothermic. study would help designing optimized systems generation.
