Multi-lobed porous ceramic body and process for making the same
A carrier having at least three lobes, a first end, a second end, a wall between the ends and a non-uniform radius of transition at the intersection of an end and the wall is disclosed. A catalyst comprising the carrier, silver and promoters deposited on the carrier and useful for the epoxidation of olefins is also disclosed. A method for making the carrier, a method for making the catalyst and a process for epoxidation of an olefin with the catalyst are also disclosed.

Alkylene oxide synthesis
Direct epoxidation of propene is carried out on electrochemically tuned mixed oxide catalyst surfaces in a single chamber reactor with mixed reaction gas of hydrocarbon and oxygen. Yield and selectivity improvement compared to platinum- or silver-based noble metal catalysts have been demonstrated for the same reactor set up. Increase in propylene oxide yield has been demonstrated when a cell voltage is applied.

Gas separations with redox-active metal-organic frameworks
Fe.sub.2(dobdc) has a metal-organic framework with a high density of coordinatively-unsaturated Fe.sup.II centers lining the pore surface. It can be effectively used to separate O.sub.2 from N.sub.2 and in a number of additional separation applications based on selective, reversible electron transfer reactions. In addition to being an effective O.sub.2 separation material, it can be used for many other processes, including paraffin/olefin separation, nitric oxide/nitrous oxide separation, acetylene storage, and as an oxidation catalyst.
