Abstract

In this study, activated carbon fibers (ACFs) were produced from mechanically recycled acrylic (PAN) and cotton (CO) fibers and their blend (PAN/CO) in felt form as an adsorbent for carbon dioxide capture. For this purpose, stabilization, carbonization, and chemical activation processes were applied consecutively. The effects of recycled fiber type, carbonization temperature, and activation agent impregnation ratio were investigated. The resultant ACFs were characterized by elemental analysis, SEM, FTIR, XPS, and BET analyses, and carbon dioxide adsorption capacity was tested. It was observed that the fibrous structure of all samples was preserved at all stages, although the fiber diameters were reduced. The maximum quantity of adsorbed C[O.sub.2] was found to be 3.79, 3.47, and 3.28 mmol C[O.sub.2]/g for recycled PAN, CO, and PAN/CO based samples, respectively, at 298 K at a relative pressure of 0.989. It was conducted that the carbon dioxide adsorption performance was affected by both the ACF surface area and the nitrogen content in the structure. It was concluded that recycled fiber-based ACFs as C[O.sub.2] adsorbents could be successfully produced with reasonable adsorption performance as a sustainable alternative. Highlights * Activated carbon fibers were produced from recycled acrylic and cotton fibers * Fibrous structure was preserved, but fiber diameters decreased * Reasonable carbon dioxide adsorption capacity was attained * Recycled fiber-based ACFs could be a sustainable alternative to C[O.sub.2] adsorbents KEYWORDS acrylic, activated carbon fiber, carbon dioxide adsorption, cotton, recycled fiber, 1 | INTRODUCTION Climate change is one of the main problems today, and the concentration of greenhouse gases in the atmosphere is directly linked to the average global temperature on [...]
