摘要： The present invention relates to the preparation of Multimetallic Anionic Clays (MACs) through a simple method, which are then shaped by spray-drying into microspheres with adequate mechanical properties, suitable to be fluidized. The microspheres are appropriate for application as additives in the Fluid Catalytic Cracking (FCC) process, i.e. blended with the conventional catalyst, to in situ remove sulfur oxides (SOx) from the combustion gases produced in the regeneration stage of the FCC process, when cracking sulfur-containing hydrocarbon feeds. An oxidation promoter is added to the MACs in order to promote the oxidation of SO2 to SO3, a key step in SOx removal, providing more efficient and versatile materials, which are apt to be used in atmospheres with variable oxygen concentration.
