Abstract
The invention covers a process for obtaining an alkaline earth or rare earth metal-P-modified molecular sieve (M-P-modified molecular sieve) comprising the following steps: The invention also covers a catalyst composite comprising: The catalyst of the invention can also be used in a process for making an olefin product from an oxygen-containing, halogenide-containing or sulphur-containing organic feedstock wherein said oxygen-containing, halogenide-containing or sulphur-containing organic feedstock is contacted in the XTO reactor with the catalyst composite according to the invention under conditions effective to convert the oxygen-containing, halogenide-containing or sulphur-containing organic feedstock to olefin products (the XTO reactor effluent). The catalyst composite of the invention can also be used in addition or alternatively in an OCP process.
