Catalytic compositions and sequential catalytic methods are generally described. In some embodiments, a composition comprises a first catalyst comprising a Cu-modified zeolite, and a second catalyst capable of a coupling reaction between (a) an intermediate resulting from a reaction of a reactant at the first catalyst, and (b) a co-reagent, wherein a rate of diffusion of the co-reagent within one or more cages and/or pores of the first catalyst is lower than a rate of diffusion of the intermediate within the one or more cages and/or pores of the first catalyst.

Catalytic compositions for the oxidation of substrates

A method may include: contacting a light paraffin feed comprising ethane, propane, butane, naphtha or combinations thereof with a restrained catalyst in a reactor; converting at least a portion of the light paraffin feed to ethylene, propylene, or combinations thereof with an olefin selectivity of at least 70 wt. % and methane selectivity of less than 15 wt. %; and withdrawing a product stream from the reactor.

Selective olefins production from light paraffins

The disclosure is related to various modified EMM-23 materials, processes, and uses of the same.

EMM-23 materials and processes and uses thereof

A novel metal organic framework, EMM-39, is described having the structure of UiO-66 and comprising bisphosphonate linking ligands. EMM-39 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-39, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.

Metal organic frameworks, their synthesis and use

A novel metal organic framework, EMM-42, is described having the structure of UiO-66 and comprising bisphosphonate linking ligands. EMM-42 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-42, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.
