    Abstract: Compositions for reduction of NOx generated during a catalytic cracking process, preferably, a fluid catalytic cracking process, are disclosed. The compositions comprise a fluid catalytic cracking catalyst composition, preferably containing a Y-type zeolite, and a particulate NOx reduction composition containing ferricrite zeolite particles. Preferably, the NOx reduction composition contains ferrierite zeolite particles bound with an inorganic binder. In the alternative, the ferrierite zeolite particles are incorporated into the cracking catalyst as an integral component of the catalyst. NOx reduction compositions in accordance with the invention are very effective for the reduction of NOx emissions released from the regenerator of a fluid catalytic cracking unit operating under FCC process conditions without a substantial change in conversion or yield of cracked products. Processes for the use of the compositions are also disclosed.

    Abstract translation: 公开了用于还原在催化裂化过程中产生的NOx,优选流化催化裂化过程的组合物。 该组合物包含优选含有Y型沸石的流化催化裂化催化剂组合物和含有铁氰沸石颗粒的颗粒状NOx还原组合物。 优选地,NOx还原组合物含有与无机粘合剂结合的镁碱沸石颗粒。 替代方案中,镁碱沸石颗粒作为催化剂的组成成分加入到裂化催化剂中。 根据本发明的NOx还原组合物对于在FCC工艺条件下操作的流化催化裂化装置的再生器中释放的NOx排放的降低非常有效,而没有破裂产物的转化率或产率的显着变化。 还公开了使用组合物的方法。
