    摘要: 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)Q.sub.2 O:(y)M.sub.2/n O:(z)L.sub.2 O.sub.3 :100SiO.sub.2wherein Q.sub.2 O 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. The zeolite is useful in the process of catalytic conversion of alcohols and/or oxygenates to gasoline-grade hydrocarbons.

    摘要: As synthesized by conventional technique, zeolite ZSM-5 is crystallized in the presence of substantial amount of tetraalkylammonium cations, the alkyl groups of which contain 2 to 5 carbon atoms, such as, for example, tetrapropylammonium. When synthesized in the conventional way, ZSM-5 contains tetraalkylammonium cations as well as a substantial amount of sodium ions. To obtain a more catalytically active form of ZSM-5, the sodium ions must be exchanged to very low levels. By synthesizing zeolite ZSM-5 according to the present method, i.e., in the presence of a combination of an amine and a halide in the presence of a mutual solvent and with a specifically defined reaction mixture composition, ZSM-5 having different organic nitrogen-containing cations but the same crystal structure as conventionally prepared ZSM-5 is obtained. The ZSM-5 prepared in accordance herewith is very low in sodium content as synthesized and has a crystal size of from about 0.05 microns to about 20 microns.
