  • Systems and methods for zeolite catalyst pore blocking modifications for hydrocarbon conversion reactions
    Patent number: 11090643
    Abstract: Systems and methods for production of externally-pore-blocked, internally-pore-opened modified zeolite crystals, the method including mixing zeolite crystals with an organic pore blocking agent; heating the zeolite crystals mixed with the organic pore blocking agent to block internal pores of the zeolite crystals and produce internally-pore-blocked zeolite crystals; mixing the internally-pore-blocked zeolite crystals with an external pore blocking agent; and calcining the internally-pore-blocked zeolite crystals mixed with the external pore blocking agent, to re-open internal pores via decomposition of the organic pore blocking agent and to block external pores via formation of a silica layer over external pores of the zeolite crystals, forming the externally-pore-blocked, internally-pore-opened modified zeolite crystals.
