    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: a). selecting a molecular sieve selected from one of: - a P-modified molecular sieve which contains at least 0.3 wt% of P - a molecular sieve which is modified with P prior to or during step b) thereby introducing at least 0.3 wt % of P b). contacting said molecular sieve with an alkaline earth or rare earth metal-containing compound (M-containing compound) to introduce at least 0.05 wt% of the alkaline earth or rare earth metal to the molecular sieve. The invention also covers a catalyst composite comprising: a). at least 10 wt % of a M-P-modified molecular sieve comprising at least 0.05 % by weight of an alkaline earth or rare earth metal (M) and at least 0.3 wt% of P, b). optionally metal phosphate, c). optionally matrix material, and d). optionally binder. 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.

    Abstract translation: 本发明涉及一种获得碱土金属或稀土金属-P改性分子筛(M-P-改性分子筛)的方法,包括以下步骤:a)。 选择选自以下之一的分子筛:P-改性分子筛,其含有至少0.3重量%的P - 在步骤b)之前或期间用P改性的分子筛,由此引入至少0.3重量%的P b)。 使所述分子筛与含碱土或含稀土金属的化合物(含M化合物)接触,以将至少0.05重量%的碱土金属或稀土金属引入到分子筛中。 本发明还涵盖了一种催化剂复合材料,其包括:a)。 至少10重量%的包含至少0.05重量%的碱土金属或稀土金属(M)和至少0.3重量%的P,b)的M-P改性分子筛。 任选的金属磷酸盐,c)。 任选的基质材料,和d)。 可选粘合剂。 本发明的催化剂也可用于从含氧,含卤素或含硫有机原料制备烯烃产物的方法,其中所述含氧卤化物或含硫有机原料接触 在具有将含氧,含卤素或含硫有机原料转化为烯烃产物(XTO反应器流出物)的条件下,具有根据本发明的催化剂复合材料的XTO反应器。 本发明的催化剂复合物也可以在OCP方法中加入或替代地使用。
