WAX COMPOSITIONS COMPRISING LINEAR OLEFIN DIMERS OR HODROGENATED VARIANTS THEREOF AND METHODS FOR PRODUCTION THEREOF

Wax compositions may be obtained by providing an olefinic feed comprising a first linear alpha olefin having m carbon atoms and a second linear alpha olefin having n carbon atoms, wherein m and n are independently selected integers each ranging from about 12 to about 100, and the olefinic feed optionally comprises one or more internal olefins and/or one or more branched olefins; contacting the olefinic feed with a metal carbene catalyst in a reactor; forming ethylene and a hydrocarbon substance comprising a linear olefin dimer comprising two carbon atoms less than a sum of m and n; removing the ethylene from the reactor while forming the linear olefin dimer; and isolating a wax composition comprising the linear olefin dimer, a hydrogenated reaction product thereof, or any combination thereof.

Efficient heterogeneous dual catalyst systems for alkane metathesis

A fully heterogeneous and highly efficient dual catalyst system for alkane metathesis (AM) has been developed. The system is comprised of an alumina-supported iridium pincer catalyst for alkane dehydrogenation/olefin hydrogenation and a second heterogeneous olefin metathesis catalyst. The iridium catalysts bear basic functional groups on the aromatic backbone of the pincer ligand and are strongly adsorbed on Lewis acid sites on alumina. The heterogeneous systems exhibit higher lifetimes and productivities relative to the corresponding homogeneous systems as catalyst/catalyst interactions and bimolecular decomposition reactions are inhibited. Additionally, using a two-pot device, the supported Ir catalysts and metathesis catalysts can be physically separated and run at different temperatures. This system with isolated catalysts shows very high turnover numbers and is selective for the formation of high molecular weight alkanes.
