Abstract

Processes are provided for preparing molecular sieves of framework structure MEI, TON, MRE, MWW, MFS, MOR, FAU, EMT, or MSE. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier L selected from the group consisting of cationic surfactants having a quaternary ammonium group comprising at least one hydrocarbyl group having at least 12 carbon atoms, nonionic surfactants, anionic surfactants, sugars and combinations thereof.
