<p>HIGHLY SILICEOUS POROUS CRYSTALLINE MATERIAL A new zeolite, designated ZSM-22, is disclosed and claimed. The new zeolite has the composition, in the anhydrous state, expressed in terms of mole ratios of oxides as follows: (x)Q2O:(y)M2/nO:(z)L2O3:100SiO2 wherein Q2O is the oxide form of an organic compound containing an element of Group 5-B (as defined in the Table of the Elements National Bureau of Standards, Fischer Scientific Co. Catalog No. 5-702-10), e.g., N or P, preferably N, containing at least one alkyl or aryl group having at least 2 carbon atoms, M is an alkali or alkaline earth metal having a valence n, e.g., Na, K, Cs or Li and wherein x = 0.01-2.0, y = 0-2.0, z = 0-5, and L = Al. Zeolite ZSM-22 has an X-ray diffraction pattern as set forth in Table I of the specification.</p> |
