The present invention is directed to certain catalyst compositions and processes that are capable of reducing sulfur compounds normally found as part of the gasoline fraction streams of fluid catalytic cracking processes. The present invention is a cracking catalyst composition comprising a zeolite in combination with a Lewis Acid containing component, wherein the cracking catalyst composition comprises 0.2% Na2O or less. It has been found that sulfur compounds in hydrocarbon feeds to fluid catalytic cracking processes can be reduced by at least 15% compared to the same composition, which does not comprise the aforementioned Lewis Acid containing component.
Certains processus et compositions de catalyse sont aptes à réduire les composés de soufre se trouvant normalement dans des courants de fraction d'essence de processus de craquage catalytique fluide. La composition de catalyse de craquage renferme un zéolite combiné à un acide Lewis contenant un composant, la composition renfermant entre 0,2 % de Na2O ou moins. Il a été découvert que les composés de soufre dans les charges d'hydrocarbures peuvent être réduits d'au moins 15 % par rapport à la même composition qui ne comprend pas le composant contenant l'acide Lewis.
