Adsorption of Methylene Blue Using As-Developed Binderless Hot-Pressed Granular Activated Carbon Derived from Sugarcane Bagasse Residues.

ABSTRACT: This study aims to develop sugarcane bagasse-derived granular activated carbon (SCB-GAC) as a biobased adsorbent for methylene blue (MB) adsorption in an aqueous solution using a binderless hot-pressed (HP) technique. HP conditions, i.e., mechanical pressure, temperature, and holding time, were systematically fine-tuned to first produce HP-SCB pellets. HP pellets were further carbonized at 500 °C for 1 h to obtain biochar pellets, which were cut into granules prior to activation with steam under the optimum conditions of 850 °C for 30 min. The mechanical pressure showed the most significant influence on the yield and textural properties of the as-developed HP-SCB-GAC. The optimal HP condition of 20 MPa at 270 °C for 30 min resulted in a substantial yield (53.7%) of the developed HP-SCB-GAC
