    摘要: The invention involves a process for converting an oxygenate-containing feed into an olefin-containing product comprising: (a) providing a co-catalyst oxide of a metal from Groups 2-4 of the Periodic Table of Elements, Lanthanides, Actinides, and combinations thereof, (b) contacting the metal oxide with nitromethane under conditions sufficient for the nitromethane to adsorb onto the metal oxide; (c) analyzing the nitromethane-adsorbed metal oxide using NMR to determine a basic site density of the metal oxide; (d) providing a catalyst system comprising a primary catalyst comprising aluminosilicates, aluminophosphates, silicoaluminophosphates, and metal-containing derivatives and combinations thereof, and the co-catalyst metal oxide whose basic site density is ≧0.085 mmol/g and whose BET surface area is ≧20 m2/g; (e) contacting the oxygenate-containing feedstock with the catalyst system under conditions sufficient to form an olefin-containing product; and (f) separating the olefin-containing product into at least ethylene and/or propylene.
