Abstract
Systems and methods for production of consistently-sized ZSM-22 zeolite catalyst crystals, a method including preparing an aluminate solution; preparing a silica solution; mixing the aluminate solution and the silica solution to form a zeolite-forming solution; heating the zeolite solution with microwave irradiation in a first, a second, a third, and a fourth distinct isothermal stage to produce the consistently-sized ZSM-22 zeolite catalyst crystals within a pre-selected crystal size range using a non-ionic surfactant.
