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.
