Abstract
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 HxMeyAlzPkO2 wherein, y+z+k=1 x<=y said molecular sieve having predominantly a plate crystal morphology in which the width (W) and the thickness (T) are W/T is >=10 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 MeO2 insoluble in the TIA, reactive sources of AI203 and P205, 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. The present invention also relates to catalysts consisting of the above MeAPO molecular and relates to a process for making an olefin product from an oxygen-containing, halogenide-containing or sulphur-containing feedstock.
