- Abstract
This study investigates the optimization of production parameters for rice husk-derived activated carbon, targeting its effective application in direct air capture (DAC) technology. Various chemical activation agents--potassium hydroxide (KOH), urea, and their combination--and activation temperatures (600°C, 700°C, and 800°C) were explored using pyrolysis. The morphology of the resulting activated carbon was analyzed via scanning electron microscopy (SEM) and ImageJ. Results demonstrate that the choice of activation agent and temperature significantly influence pore diameter size and quantity. Higher temperatures led to smaller pore diameters and an increased number of pores. The combination of KOH and urea at 800°C produced the most favorable particle size (0.811 µm), suitable for applications requiring a well-defined pore structure. This combination also exhibited the most even pore distribution and highest pore density. These findings provide valuable insights for optimizing the production of rice husk-derived activated carbon, contributing to the development of sustainable and effective sorbents for CO2 capture in DAC technology. Additionally, they offer potential for broader applications of husk-activated carbon in various industrial and environmental fields. [ABSTRACT FROM AUTHOR]
