  • Catalytic cracking materials based on ITQ-7 zeolites and their use in hydrocarbons cracking processes
    Patent number: 6716784
    Abstract: Catalytic compositions are described for hydrocarbons cracking containing at least two zeolitic components of which at least one zeolitic component containing aluminium in its structure is selected from among ITQ-7 zeolites, intergrowths of ITQ-7 zeolites, ITQ-7 zeolites exchanged with rare earths, intergrowths of ITQ-7 zeolites exchanged with rare earths, and combinations of them. These combinations are of utility as catalysts for cracking in FCC units and permit C3 and C4 olefins to be efficiently obtained along with high yields of gasoline. Also described is the use of a zeolitic material containing aluminium in its structure and selected from among ITQ-7 zeolites, intergrowths of ITQ-7 zeolites, ITQ-7 zeolites exchanged with rare earths, intergrowths of ITQ-7 zeolites exchanged with rare earths, and combinations of them, as a catalytic material in hydrocarbon catalytic cracking processes.
