The invention relates to a conversion process of a feedstock, preferably an oxygenated feedstock, into one or more olefin(s), preferably ethylene and/or propylene, in the presence of a molecular sieve catalyst composition that includes a molecular sieve and a Group 3 metal oxide and/or an oxide of a
The invention relates to a conversion process of a feedstock, preferably an oxygenated feedstock, into one or more olefin(s), preferably ethylene and/or propylene, in the presence of a molecular sieve catalyst composition that includes a molecular sieve and a Group 3 metal oxide and/or an oxide of a Lanthanide or Actinide series element. The invention is also directed to methods of making and formulating the molecular sieve catalyst composition useful in a conversion process of a feedstock into one or more olefin(s).

We claim: 1. An integrated process for making one or more olefin(s), the integrated process comprising the steps of: (a) passing a hydrocarbon feedstock to a syngas production zone to produce a synthesis gas stream; (b) contacting the synthesis gas stream with a catalyst to form an oxygenated feeds
We claim: 1. An integrated process for making one or more olefin(s), the integrated process comprising the steps of: (a) passing a hydrocarbon feedstock to a syngas production zone to produce a synthesis gas stream; (b) contacting the synthesis gas stream with a catalyst to form an oxygenated feedstock; (c) converting the oxygenated feedstock into the one or more olefin(s) in the presence of a molecular sieve catalyst composition comprising a molecular sieve and an active metal oxide, the metal selected from Group 3 or Lanthanide or Actinide series elements of the Periodic Table of Elements; and (d) polymerizing the one or more olefin(s) in the presence of a polymerization catalyst into a polyolefin. 2. The integrated process of claim 1, wherein the molecular sieve catalyst composition comprises an alumina sol binder and a clay matrix material. 3. The integrated process of claim 1, wherein the active Group 3 metal oxide or active oxide of a Lanthanide or Actinide series element is selected from at least one of the group consisting of yttrium oxide, scandium oxide, lanthanum oxide, cerium oxide, praseodymium oxide, and neodymium oxide. 4. The integrated process of claim 1, wherein the molecular sieve comprises SAPO-34. 5. The integrated process of claim 1, wherein the metal of the active Group 3 metal oxide is selected from one of the group consisting of yttrium, scandium, and lanthanum. 6. The integrated process of claim 1, wherein the metal of the active oxide of a Lanthanide or Actinide series element is selected from one of the group consisting of cerium, praseodymium, neodymium, samarium, and thorium. 7. The integrated process of claim 1, wherein the active Group 3 metal oxide or the active oxide of a Lanthanide or Actinide series element is non-acidic. 8. The integrated process of claim 1, wherein the Group 3 metal oxide is yttrium oxide or lanthanum oxide. 9. The integrated process of claim 1, wherein the molecular sieve is a silicoaluminophosphate molecular sieve and/or an aluminophosphate molecular sieve. 10. The integrated process of claim 1, wherein the molecular sieve comprises a CHA framework-type, and the metal from the Group 3 metal oxide and the oxide of a Lanthanide or Actinide series element is different from any binder metal and any matrix material metal present in the molecular sieve catalyst composition. 11. The integrated process of claim 10, wherein the molecular sieve further comprises an AEI framework-type. 12. The integrated process of claim 1, wherein the molecular sieve catalyst composition has a density in the range of from 0.6 g/cc to 3 g/cc. 13. The integrated process of claim 2, wherein the molecular sieve is a silicoaluminophosphate molecular sieve. 14. The integrated process of claim 1, wherein the weight percent of molecular sieve to the active Group 3 or Lanthanide or Actinide series metal oxide is in the range of from 30 weight percent to 400 weight percent, based on the total weight of the molecular sieve and the total weight of the Group 3 or the Lanthanide or Actinide series metal oxide in the composition.
