Abstract
A method for converting starting material to olefins comprising contacting the starting material with a small pore molecular sieve catalyst under effective conditions to produce olefins, wherein the molecular sieve has been modified after synthesis by incorporation of a transition metal ion using a transition metal compound, wherein the transition metal ion is selected from the group comprising Groups VIB, VIIB, or VII or mixtures thereof.
Claims17
A method for converting oxygenates to olefins comprising
- contacting said oxygenates with a small pore molecular sieve catalyst under production conditions effective to produce olefins;
- wherein said molecular sieve catalyst comprises a framework, and said framework is treated after synthesis with a transition metal compound comprising transition metal ions under catalyst treatment conditions effective to incorporate at least a portion of said transition metal ions onto said framework, wherein said transition metal ions are selected from the group consisting of Groups VIB, VIIB, or VIII and mixtures thereof.
A method for converting oxygenates to olefins comprising
- contacting said oxygenates with a small pore molecular sieve catalyst under production conditions effective to produce olefins,
- wherein said molecular sieve catalyst comprises a framework, and said framework is treated after synthesis with a transition metal compound comprising transition metal ions under catalyst treatment conditions effective to incorporate at least a portion of said transition metal ions onto said framework, wherein said transition metal ions are selected from the group consisting of nickel, cobalt, and mixtures thereof.
A method for converting oxygenates to olefins comprising:
- contacting said oxygenates with a molecular sieve catalyst selected from the group consisting of a SAPO, ZSM-34, a chabazite, an erionite, and mixtures thereof, under production conditions effective to produce olefins;
- wherein said molecular sieve catalyst comprises a framework comprising pores having a size less than about 5.0 Angstroms;
- and
- wherein said framework is treated after synthesis with a transition metal compound comprising transition metal ions selected from the group consisting of nickel, cobalt, and mixtures thereof, under catalyst treatment conditions effective to incorporate at least a portion of said transition metal ions onto said framework.
