Study on the effective utilization of red mud for catalytic use and metal recovery

In the primary part of the study, red mud material is directly used as catalysts with or without modification. The red mud material is characterized using Inductively coupled ... plasma optical emission spectroscopy (ICP-OES), X-ray diffraction (XRD), temperature program reduction using H2 (H2-TPR) and N2 adsorption/desorption method for understanding the structure, reducibility/H2 uptake of the sample and the BET surface area, respectively. The basicity and acidity of the catalyst is analyzed using temperature program desorption using carbon dioxide (CO2-TPD) and ammonia (NH3-TPD), respectively, to determine the physicochemical properties. All the prepared samples were tested and their performance for various applications in fixed bed test reactor at the desired temperature and pressure. he second part of the project is to explore the opportunities for metal recovery from red mud using our collaboration and NDA with international parties. This aims at developing an efficient recovery method with offers 90% reduction in CO2 emission compared to the conventional recovery methods
