A mixture can include 0.01 to 30 weight % of a medium or large pore crystalline silicoaluminate, silicoaluminophosphate materials, or silicoaluminate mesoporous molecular sieves (A), and 99.99 to 70 weight % of a MeAPO molecular sieve. The mixture can be included in a catalyst. An XTO process can include contacting an oxygen-containing, halogenide-containing, or sulphur-containing organic feedstock with the catalyst under conditions effective to convert the organic feedstock to olefin products. A combined XTO and OCP process can include contacting the organic feedstock with the catalyst at conditions effective to convert at least a portion of the organic feedstock to form an XTO reactor effluent including light olefins and a heavy hydrocarbon fraction, separating the light olefins from the heavy hydrocarbon fraction, and contacting the heavy hydrocarbon fraction in an OCP reactor at conditions effective to convert at least a portion of the heavy hydrocarbon fraction to light olefins.
混合物可以包含0.01至30重量%的中孔或大孔结晶硅铝酸盐、硅铝磷酸盐材料或硅铝酸盐介孔分子筛(A),以及99.99至70重量%的MeAPO分子筛。该混合物可以包含在催化剂中。XTO过程可以包括将含氧、含卤素或含硫有机原料与催化剂接触,以有效地将有机原料转化为烯烃产品。联合XTO和OCP过程可以包括在有效条件下将有机原料与催化剂接触,以将至少部分有机原料转化为形成包括轻烯烃和重烃分馏物的XTO反应器流出物,将轻烯烃与重烃分馏物分离,并在OCP反应器中以有效条件将至少部分重烃分馏物转化为轻烯烃。
