Document Type and Number:
WIPO Patent Application WO/2017/082345
Kind Code:
A1
Abstract:
[Problem] To provide an additive for a fluid catalytic cracking (FCC) catalyst used with an FCC catalyst in FCC, the additive making it possible to increase the yield of lower olefins. [Solution] An additive for an FCC catalyst used in manufacturing lower olefins, said additive containing: 20−70% by mass of modified ZSM-5 zeolite such that (1) the volume of pores having a diameter of 2 nm or less in pore volume measurements using the MP method is in the range of 0.15−0.20 mL/g , (2) the volume of pores having a diameter of 2.4−50 nm in pore volume measurements using the BJH method is in the range of 0.05−0.15 mL/g, and (3) the ammonia adsorption amount is in the range 1.0−2.0 mmol/g; a filler; and a binder comprising phosphorus- and aluminum-containing components for binding the particles of the filler and the modified ZSM-5 zeolite. The phosphorus content (according to ICP emission spectroscopy) is 5−20% by mass expressed in terms of P2O5.
