Beschreibung
Zusammenfassung:	The present invention provides additives for reducing SOx emission in hydrocarbon fluid catalytic cracking units, prepared on the basis of an alumina substrate, with a large surface area of at least 150 m2/g and a large pore volume of at least 0.25 cm3/g, and containing calcium in a concentration of at least 5% in the form of calcium oxide and an oxyreduction promoter in a concentration range from 1 to 5% m/m in the form of the oxide thereof. La présente invention concerne des additifs pour la réduction des émissions de SOx dans des unités de craquage catalytique fluide d'hydrocarbures, préparés à partir d'un support du type alumine et présentant une surface active importante d'au moins 150 m2/g, et un volume poreux élevé d'au moins 0,25 cm3/g, les éléments suivants étant incorporés : du calcium sous forme d'oxyde de calcium, en concentration d'au moins 5%, et un agent promoteur d'oxydoréduction sous forme de son oxyde, en concentration comprise entre 1 et 5% m/m. A presente invenção provê aditivos para redução das emissões de SOx em unidades de craqueamento catalítico fluido de hidrocarbonetos preparados a partir de uma suporte do tipo alumina, com alta área superficial, pelo menos 150 m2/g, e um alto volume poroso, pelo menos 0,25 cm3/g, tendo incorporados: cálcio, na forma de óxido de cálcio em concentração de pelo menos 5%; e um agente promotor de oxirredução, na forma de seu óxido, na faixa de concentração entre 1 e 5 % m/m.
