    摘要: A method of preparing aromatics processing catalysts which comprises incorporating a noble metal with a member or members of a useful class of zeolites, with such incorporation occurring after zeolite crystallization, but prior to final catalyst particle formation, i.e. extrusion into particles. Said useful class of zeolites is characterized by a silica to alumina mole ratio of at least 12 and a Constraint Index in the approximate range of 1 to 12.

    摘要: A method is provided for obtaining crystalline dealuminized products by treating a slurry of a crystalline aluminosilicate zeolite in an aqueous solution of an ammonium or alkali metal salt which upon acidification yields an anion which complexes with aluminum by adding to said slurry a water-soluble acid having a first ionization constant greater than 10.sup.-2 at a rate such that a controlled amount of aluminum is removed from the zeolite to yield a resulting product from which at least about 10% and as much as about 85% of the initial aluminum has been removed while retaining more than 60% of the original crystallinity.

    摘要: A new synthetic porous crystalline material, designated EMM-1, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making EMM-1 in the presence of HF using various organic nitrogen compounds as directing agents. Aluminum-containing EMM-1 can be produced either by inclusion of Al in the synthesis, or by incorporation of B or Ga in the synthesis, followed by post treatment with aluminum nitrate or other sources of Al. EMM-1 is useful as an acid catalyst and as an adsorbent.
