AI Technical Summary
Existing honeycomb catalysts are prone to detachment during the preparation process, leading to performance degradation. Furthermore, the secondary calcination process is complex and energy-intensive, making it difficult to effectively remove ammonia in high-humidity environments.
A honeycomb ceramic monolithic catalyst was prepared by mixing Al2O3 powder with an active component precursor, followed by vacuum rotary evaporation and drying, then mixing with a molding aid, extruding and calcining in one step, thus avoiding secondary calcination. Al2O3 was used as a carrier and molding component to improve mechanical strength and stability.
The prepared honeycomb ceramic monolithic catalyst exhibits good water resistance and stability under high humidity conditions, making it suitable for ammonia removal in public toilets and farms, simplifying the process and reducing energy consumption.
