Abstract
Novel catalytic compositions for cracking of crude oil fractions are disclosed. The catalytic compositions comprise a basic material. When used in a cracking process, preferably a FCC process, the resulting LCO and HCO fractions have desirably low aromatics levels. Further disclosed is a one-stage FCC process using the catalytic composition of the invention. Also disclosed is a two-stage FCC process for maximizing the LCO yield.
Claims20
An FCC process comprising the step of contacting an FCC feedstock with a catalytic composition under FCC reaction conditions, wherein said catalytic composition comprises a basic material, and wherein said catalytic compositions are substantially free of acidic zeolite.
A two-stage cracking process for cracking a feedstock selected from vacuum gasoils, hydrotreated vacuum gasoils, coker gasoils, atmospheric residues, vacuum residues and the hydrotreated products thereof, characterized in that at least one of the stages is a fluid catalytic cracking process in which the catalytic composition comprises a basic material, and wherein said catalytic composition is substantially free of acidic zeolite.
