Microwave-assisted enhanced activation of date palm leaf char for optimized CO₂ adsorption.

ABSTRACT: This study presents a novel hybrid approach for producing mesoporous activated carbon (AC) from date palm leaves by integrating conventional carbonization with microwave-assisted activation. K₂CO₃ was utilized for chemical activation to enhance adsorption performance. Three critical parameters, namely microwave power, residence time, and activation temperature, were investigated focusing on yield, temperature ramp-up time, and CO₂ capture capacity. Results reveal that both microwave power and activation temperature were pivotal in influencing the yield and adsorption efficiency. Microwave-assisted activation (850 W, 500 °C, 7 min) yielded an optimal CO₂ adsorption capacity of 126.7 mg/g at 25 °C and 1 bar, with 78% and 76% reductions in activation energy and processing time, respectively.
