Abstract
In removing sulfur oxides from flue gas in a cracking catalyst regenerator in the presence of a silica-containing particulate catalyst by reacting the sulfur oxides with alumina in a particulate solid other than the catalyst, activity loss in the alumina as a result of migration of silica from the catalyst particles to the alumina-containing particles is lessened by using alumina-containing particles which contain sodium, manganese or phosphorus.
