SRC denitration catalyst
There are many reasons for catalyst deactivation. The study of catalyst deactivation is of great significance to the research and practice of catalytic theory. When the activity of the catalyst decreases and its performance deteriorates to a certain extent, the catalyst should be replaced. In the operating costs, in addition to the consumption of ammonia, the cost of catalyst replacement accounts for most of the costs. For reversibly poisoned catalysts and catalysts with reduced activity, they can be reused after regeneration. The regeneration cost is only 20% to 30% of the total replacement cost, and the activity can be restored to 90% to 100% of the original performance. In addition, the waste SCR denitration catalyst that cannot be regenerated contains valuable metals such as vanadium, and direct disposal will cause environmental pollution. Vanadium is a rare metal. There are not many vanadium ores enriched in nature, and the extraction and separation of vanadium is relative
