Estimating the term…
The present invention relates to catalysts, catalyst systems, and processes for the production of valuable light olefins, such as C2-C4 olefins (ethylene, propylene, and/or butenes) from paraffinic hydrocarbons, such as propane, through dehydrogenation and metathesis. Some particular aspects relate to the discovery of non-precious metal catalysts and catalyst systems utilizing such catalysts, for example in the case of being in an admixture with a metathesis catalyst, which advantageously exhibit high performance in terms of activity, selectivity, and stability. Other advantages can include a reduced production of byproducts (e.g., methane and ethane) that result from undesired side reactions, in addition to benefits that may be attained through the addition of a sulfur-bearing compound (e.g., H2S).
A paraffin dehydrogenation and metathesis catalyst system comprising:
A paraffin dehydrogenation and metathesis catalyst comprising:
11-15. (canceled)
A paraffin dehydrogenation and metathesis catalyst system comprising at least one catalyst bed comprising a physical mixture of:
18-21. (canceled)
30-36. (canceled)
