Abstract : The amount of carbon dioxide (CO2) in the atmosphere has been increasing; since the industrial revolution, making CO2 emissions is the significant contribution to change the climate. Business cost waste biomass–based adsorbent materials are utilised for the capture of CO2 recent years. In this present study, a hot plate combustion method (HPCM) was used to synthesis porous activated carbon from wild sugarcane. The as-synthesised adsorbents were examined using X-ray dispersive spectroscopy, Fourier transform infrared (FTIR) spectrum, and field-emission scanning electron (FE-SEM) microscopy. Studies on thermodynamics were carried out. Go, Ho, and So were computed, and the process viability was examined. For sugarcane activated carbon, the experimental isotherm results were characterised using Langmuir, Freundlich, D-R, Temkin, and Sips adsorption isotherms. The Langmuir model, with a co-efficient R2 of 0.988 and the adsorption rate is 1.225 × 10−3 mol/g/min, gives the best fit with the adsorption of the CO2 on adsorbent. The activated carbon was found to be effective for CO2 adsorption process and the calculated and experimental qe values are same with R2 value of 0.9888, which demonstrates that the system is governed by pseudo-second-order kinetics. Equilibrium point was attained at 90 min.
