Abstract

This study investigates the synthesis of activated carbon from waste tires, focusing on how heating rates influence activation energy and product quality. Through controlled experiments, the research evaluates the impact of varying thermal treatments on the activation energy and the resultant activated carbon’s surface area, pore size, and volume. The objective is to establish the optimal conditions that enhance adsorptive properties while maximizing energy efficiency in the production process. Findings indicate that slower heating rates are conducive to producing activated carbon with higher surface areas and smaller, more uniform pore sizes, traits desirable for effective adsorption. Specifically, activated carbon produced under slow heating exhibited a surface area of 621 m²/g and a pore size of 292 Å, compared to 570 m²/g and 308 Å under faster heating conditions. This demonstrates a direct correlation between the heating rate and the material’s structural characteristics that affect its adsorption capacity.

Incorporated within this study parametric model that forecasts the qualities of activated carbon for various heating regimens, facilitating the precise adjustment of the synthesis process. The study reveals a nuanced understanding of energy consumption in the synthesis process. Lower heating rates, while beneficial for product quality, necessitate a reevaluation of energy expenditure to ensure economic viability. Conversely, the slight reduction in quality observed with rapid heating suggests a potential for time and energy savings, offering a trade-off between efficiency and product performance. The research bridges the gap between process parameters and activated carbon quality, providing valuable insights for the development of more sustainable, cost-effective production methods. By identifying ideal heating rates, the study paves the way for advancements in activated carbon manufacturing, promising significant improvements in environmental sustainability and economic efficiency. This contributes to a broader application of activated carbon in pollution control and resource recovery, underscoring the importance of optimized manufacturing processes.
