Abstract
The oxidative dehydrogenation of ethane comprises contacting a mixture of ethane and oxygen in an ODH reactor with an ODH catalyst under conditions that promote oxidation of ethane into ethylene. Conditions within the reactor are controlled by the operator and include, but are not limited to, parameters such as 5 temperature, pressure, and flow rate. Conditions will vary and can be optimized for a specific catalyst, or whether an inert diluent is used in the mixing of the reactants. Disclosed herein is a catalyst consisting of: Mo0-1W0.3-1V0.2-0.4Te0.06-0.10Fe0.0-0.10Nb0.08-0.18OX where X is determined by the valance of the metals.

A catalyst comprising Mo0-1W0.3-1V0.2-0.4Te0.06-0.10Fe0.0-0.10Nb0.08-0.18Ox where X is determined by the valence of the metals, wherein the catalyst comprises Mo.
An article, comprising:
- a support;
- and
- a catalyst supported by the support,
- wherein:
- the support comprises at least one member selected from the group consisting of oxides of titanium, zirconia, aluminum, niobium, magnesium, yttrium, lanthanum, or silicon, zeolites and clays;
- the catalyst comprises Mo0-1W0.3-1V0.2-0.4Te0.06-0.10Fe0.0-0.10Nb0.08-0.18Ox where X is determined by the valence of the metals;
- and
- the catalyst comprises Mo.
A method, comprising:
- contacting ethane and an oxidant with a catalyst to provide ethylene,
- wherein the catalyst comprises Mo0-1W0.3-1V0.2-0.4Te0.06-0.10Fe0.0-0.10Nb0.08-0.18Ox where X is determined by the valence of the metals, and the catalyst comprises Mo.
