摘要: 研制开发了一种降低催化裂化再生烟气SOx排放的助剂。研究了铈、钒等组分对脱硫性能的影响,得到了最佳的化学组成;开发了优化载体孔结构和连续动态浸渍活性金属的制备工艺,进一步提高了脱硫活性。工业应用结果表明,新开发的降低催化裂化再生烟气SOx排放助剂能有效减少SOx的排放,在添加2%左右(占总藏量)助剂时,再生烟气中SOx脱除率可达到70%以上,而对产品分布和主要产品性质没有明显的不良影响。

Abstract: The aim of this paper is to introduce the development of SOx transfer addictive in FCC flue gas. The effect of cerium and vanadium on De-SOx activity is discussed and the optimal composition of addictive is found. A new manufacturing method with optimized carrier pore structure and deposits metal components can dynamically increase the activity of addictive. The commercial application shows that over 70% SOx in FCC flue gas is reduced without compromising product yields and product quality,when 2% addictive is injected.
