摘要
The preparation of denitration catalyst from red mud is one of the ways to realize high value resource utilization. Currently, the main challenges in preparing denitration catalysts from RM include high calcination temperatures with long durations, complex metal loading processes, and narrow high-efficiency temperature windows. In this study, the denitration catalyst R5B5-450 was prepared using RM and biochar through acidification, grinding, and calcination. This method can effectively improve the above problems. R5B5-450 achieved over 90 % NO conversion within the temperature range of 225-400 degrees C and demonstrated significant potential for application in treating real coal-fired flue gas. This work provides a reference for the effective utilization and reduction of RM while also contributing to reducing the production cost of denitration catalysts.
