Organotemplate-free synthesis of Al-rich ZSM-35 and ZSM-22 zeolites with the addition of ZSM-57 zeolite seeds

An organotemplate-free synthesis of Al-rich ZSM-35 (Si/Al ratio at about 5) and ZSM-22 (Si/Al ratio at about 20) zeolites has been successfully shown with the addition of ZSM-57 zeolite seeds in the absence of organic templates.
