Latest Patents

Belaid Maachi holds a patent for a unique composition of .gamma.-Fe.sub.2 O.sub.3 /Fe.sub.3 O.sub.4 spinels. This patent describes oxides with a spinel structure that are substituted by trivalent and monovalent metals or doped with non-spinel derivatives. These materials are particularly effective as dehydrogenation catalysts, such as in the conversion of ethylbenzene into styrene. The preparation method involves thermally decomposing mixed iron, aluminum, and potassium salts, specifically their oxalates, in the presence of air. The resulting product is then reduced at temperatures below 400°C, often in the presence of steam and hydrogen, with optional oxidation of the reduction product. Additionally, oxides of .beta.-alumina structure are produced.
