Title : Red mud-based catalysts
Red mud, also referred to as bauxite residue, is the largest process waste produced during alumina production from bauxite ore by the Bayer method. Global red mud manufacturing is anticipated to be 200 million tons annually. Red mud accumulation has surpassed 4.6 billion tons, and the world’s red mud stockpile is steadily expanding. Red mud is considered a significant environmental threat due to its high alkalinity (pH 10–13), high salinity. Red mud presents a promising application as catalysts. The simultaneous presence of various metal oxides in the Red mud composition makes it less susceptible to catalyst poisons like sulphur, and hence it is able to retain its catalytic activity over a relatively long period of time. In addition, the coexistence of these metal oxides might ameliorate the synergistic catalytic influence between transition metals. In this presentation, the potential uses of red mud will be examined as catalyst in various reaction areas including hydrodechlorination and dechlorination, hydrogenation, oxidation, exhaust gas clean-up, and miscellaneous reactions.
Audience Takeaway Notes:
- They will be known more about catalysts derived from industrial waste and new fields of catalysts improvement based on green chemistry.
- By using catalysts derived from industrial wastes, new fields of work based on green chemistry can be provided.
- Since red mud stockpile is an environmental issue, many universities are working on it and this provides cooperation.
- It introduces the participants to the new areas of solution to the problem of red mud stockpile.
