Abstract
The present invention relates to a mixture comprising 0.01 to 30% by weight of at least one medium or large pore crystalline silicoaluminate, silicoaluminophosphate materials or silicoaluminate mesoporous molecular sieves (co-catalyst) (A) and respectively 99.99 to 70% by weight of at least a MeAPO molecular sieve. The present invention also relates to catalysts consisting of the above mixture or comprising the above mixture. The present invention also relates to a process (hereunder referred as “XTO 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 with the above catalyst (in the XTO reactor) under conditions effective to convert the oxygen-containing, halogenide-containing or sulphur-containing organic feedstock to olefin products (the XTO reactor effluent). The present invention also relates to a process (hereunder referred as “combined XTO and OCP process”) to make light olefins from an oxygen-containing, halogenide-containing or sulphur-containing organic feedstock comprising: contacting said o…
