摘要： Emissions of sulfur oxides from the regenerator of a fluidized catalytic cracking unit are reduced by selectively removing a portion of the sulfur from sulfur-containing coke deposits on deactivated cracking catalyst. This is accomplished by reaction of these deposits with limited amounts of molecular oxygen in a stripping zone at a temperature in the range from about 550.degree. to about 700.degree. C. Effluent gas from the striping zone is combined with the cracked hydrocarbon products.

摘要： A cyclic, fluidized catalytic cracking process providing reduced emissions of noxious effluents in regeneration zone flue gases is operated with homogeneous or non-homogeneous, regenerable, fluidized, solid particles which are circulated throughout the catalytic cracking process cycle and which comprise (1) a molecular sieve-type cracking catalyst, comprising a cracking catalyst matrix containing crystalline aluminosilicate distributed throughout said matrix and (2) a metallic reactant which reacts with a sulfur oxide to form a metal- and sulfur-containing compound in the solid particles. The method involves regeneration of the cracking catalyst in the presence of a metallic oxidation promoter which can also be a component of the solid particles.

摘要： Small amounts of a promoter comprising palladium and ruthenium enhance the combustion of carbon monoxide within the regeneration zone of a catalytic cracking unit without simultaneously causing the formation of excessive amounts of nitrogen oxides. The palladium-ruthenium promoter also enhances the capture of sulfur oxides by suitable absorbents within the regeneration zone of a catalytic cracking unit without causing the formation of excessive amounts of nitrogen oxides. The ratio by weight on an elemental metal basis of palladium to ruthenium is from about 0.1 to about 10.
