📄 Abstract（原文）
The continuous increase in atmospheric carbon dioxide (CO 2 ) emissions has intensified global climate change, creating an urgent need for effective carbon capture technologies. Although various adsorbents have been developed, many require specialized feedstocks and costly processing, encouraging the exploration of waste-derived alternatives. Sidoarjo Mud, an abundant mineralrich waste generated by the long-term mudflow disaster in East Java, Indonesia, contains SiO 2 , Al 2 O 3 , Fe 2 O 3 , and CaO that may contribute to CO 2 adsorption. However, its potential as a CO 2 adsorbent and the effect of pyrolysis on its adsorption performance remain largely unexplored. Therefore, this study evaluated the physicochemical characteristics and CO 2 adsorption performance of raw and pyrolyzed Sidoarjo Mud. Raw Sidoarjo Mud was dried, while pyrolyzed samples were prepared at 600 °C for 2 h under a nitrogen atmosphere. The samples were characterized using elemental, SEM, and BET analyses, while CO 2 adsorption was measured using a Micromeritics ASAP 2420 analyzer. The results showed that Sidoarjo Mud is dominated by inorganic minerals and has a high ash content of 97.27%. Pyrolysis increased surface area and pore volume and promoted cavity formation; however, raw Sidoarjo Mud exhibited a higher CO 2 adsorption capacity (0.11 mmol/g) than pyrolyzed Sidoarjo Mud (0.09 mmol/g). These findings indicate that increased surface area alone does not necessarily improve CO 2 adsorption performance and that pore size distribution plays an important role. This study provides the first systematic evaluation of pyrolysis effects on the CO 2 adsorption behavior of mineral-rich Sidoarjo Mud and demonstrates its potential as a waste-derived mineral adsorbent for carbon capture applications.
