    摘要: An improved catalyst composition is disclosed for converting synthesis gas to hydrocarbon mixtures. The catalyst comprises an iron-containing, Fischer-Tropsch catalyst and a crystalline zeolite having a silica-to-alumina ratio of greater than 200 (including zeolites containing essentially no alumina) and an (R.sub.2 O+M.sub.2 /.sub.n O):SiO.sub.2 rate of less than 1.1:1 where M is a metal other than a metal of Group IIIA, n is the valence of said metal, and R is an alkyl ammonium radical, said organosilicate being characterized by a specified x-ray diffraction pattern.

    摘要: An improved method for preparing a crystalline aluminosilicate zeolite having uniform pores and greater than 40 percent crystallinity which comprises forming a critical reaction mixture containing a source of at least two cations, silica, alumina and water, wherein at least about 70 weight percent of the alumina is provided to the reaction mixture by an alumina-containing clay being added thereto, and maintaining the reaction mixture at a temperature and pressure for a time necessary to crystallize the crystalline aluminosilicate from the reaction mixture. It is desirable to preform said reaction mixture into discrete particles such as pellets or extrudates which retain their shape and acquire substantial strength in the crystallization process.

    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, M is an alkali or alkaline earth metal having a valence n, e.g., Na, K, Cs or Li and wherein x=0-2.0, y=0-2.0, z=0-5, and L=Al. Also disclosed are methods of preparing ZSM-22, e.g., with an alkane diamine directing agent, and uses of ZSM-22 as catalysts, e.g., in hydrocarbon conversion reactions.
