According to one or more embodiments, non-agglomerated, nano-sized ZSM-22 zeolites may be synthesized by methods comprising operating a mechanical rotation drum unit at a first temperature of from 40&#xb0; C. to 60&#xb0; C. and a first speed of from 200 rpm to 1000 rpm for a first time period of from 1.3 hours to 2.7 hours; operating the mechanical rotation drum unit at a second speed of from 30 rpm to 90 rpm for a second time period of from 0.05 hours to 0.4 hours; heating the mechanical rotation drum unit at a ramping temperature of from 8&#xb0; C./minute to 12&#xb0; C./minute to a second temperature of from 115&#xb0; C. to 185&#xb0; C. at the second speed; operating the mechanical rotation drum unit at the second temperature and the second speed for a third time period of from 30 hours to 90 hours; and cooling the mechanical rotation drum unit at a fourth speed of 0 rpm.

Systems and methods for the synthesizing ZSM-22 zeolites

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.
