    • The present invention relates to metalloaluminophosphate (MeAPO) molecular sieve with lamellar crystal morphology having an empirical chemical composition on an anhydrous basis, after synthesis and calcination, expressed by the formula H x Me y Al z P k O 2 wherein, y+z+k=1 x
      said molecular sieve having predominantly a plate crystal morphology in which the width (W) and the thickness (T) are such as :
      W/T is >= 10 and advantageously ranges from 10 to 100.
      In a preferred embodiment T is
      The above metalloaluminophosphate (MeAPO) molecular sieve can be made by a method which comprises :
      a) forming a reaction mixture containing a texture influencing agent (TIA), an organic templating agent (TEMP), at least a reactive inorganic source of MeO 2 insoluble in the TIA, reactive sources of Al 2 O 3 and P 2 O 5 ,
      b) crystallizing the above reaction mixture thus formed until crystals of the metalloaluminophosphate are formed,
      c) recovering a solid reaction product,
      d) washing it with water to remove the TIA and
      e) calcinating it to remove the organic template.
      In an advantageous embodiment the MeAPO of the invention have essentially a structure CHA or AEI or a mixture thereof. Preferably they have essentially the structure SAPO 18 or SAPO 34 or a mixture thereof.
      The present invention also relates to catalysts consisting of the above MeAPO molecular sieves or comprising the above MeAPO molecular sieves.
      The present invention also relates to a process for making an olefin product from an oxygen-containing, halogenide-containing or sulphur-containing feedstock wherein said oxygen-containing, halogenide-containing or sulphur-containing feedstock is contacted with the above catalyst under conditions effective to convert the oxygen-containing, halogenide-containing or sulphur-containing feedstock to olefin products.
