Исследовано влияние ключевых параметров процесса кристаллизации – содержания натрия (Na2O/Al2O3), структурообразующего агента (HMI/Al2O3) и добавления кристаллической затравки – на фазовый состав, морфологию, пористую структуру и адсорбционные свойства получаемого материала. Показано, что оптимальными условиями являются: Na2O/Al2O3 = 2,7; HMI/Al2O3 = 15; количество кристаллической затравки – 20 мас.%. При соблюдении этих условий достигается формирование фазовочистого цеолита MCM-22 с микромезопористой структурой и высокими значениями удельной поверхности (~410 м2/г) и адсорбционной емкости по воде, бензолу и н-гептану. Установлено, что увеличение содержания натрия или темплата приводит к образованию побочных фаз (морденит, ZSM-35, ферьерит) и снижению кристалличности. Полученные данные могут быть использованы для создания эффективных гранулированных катализаторов на основе MCM-22 без связующих веществ.</p></abstract><trans-abstract xml:lang="en"><p>A promising method for preparing powdered zeolite MSM-22 with a degree of crystallinity close to 100% has been developed, which is based on the use of synthetic aluminosilicate as the main source of silicon and aluminum.
