Title:
ADDITIVE FOR FLUID CATALYTIC CRACKING CATALYST, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/131381
Kind Code:
A1
Abstract:
[Problem] To provide an additive for a FCC catalyst, which enables the production of a lower olefin such as propylene with high yield in FCC even when a raw material hydrocarbon oil contains a heavy metal in a large quantity.
[Solution] An additive for a fluid catalytic cracking catalyst, the additive containing pentasil-type zeolite and an inorganic oxide matrix, wherein the amount of the pentasil-type zeolite is 10 to 60% by mass and the pentasil-type zeolite contains phosphorus in an amount of 5 to 20% by mass in terms of the mass of P2O5, the inorganic oxide matrix contains an alumina component in such an amount that the amount of aluminum in terms of Al2O3 can become 2 to 20% by mass (in which the amount of the additive is 100% by mass), and the following formulae are satisfied: 0.02 ≤ P(-25 ppm)/P(-30 ppm) ≤ 0.40 [wherein P(-25 ppm) and P(-30 ppm) respectively represent an area ratio of a peak appearing at -25 ppm and an area ratio of a peak appearing at -30 ppm in a 31P-NMR measurement].
