Use of cationic layered materials in hydrocarbon conversion, purification, and synthesis processes, such as fluid catalytic cracking. Cationic layered materials are especially suitable for the reduction of Sox and Nox emissions and the reduction of the sulfur and nitrogen content in fuels like gasoline and diesel. A new process is provided for the preparation of cationic layered materials, which process avoids the use of metal salts and does not require the formation of anionic clay as intermediate.

La présente invention concerne l'utilisation de matériaux cationiques en couches dans des procédés de conversion, de purification et de synthèse d'hydrocarbures, tels que le craquage catalytique fluide. Des matériaux cationiques en couches sont spécialement conçus pour la réduction d'émissions SOx et NOx et la réduction de la teneur en soufre et en azote de carburants comme l'essence et le diesel. L'invention concerne un nouveau procédé de préparation de matériaux cationiques en couches, ledit procédé permettant d'éviter l'utilisation de sels métalliques et ne nécessitant pas la formation d'argile anionique en tant qu'intermédiaire.
