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.

Wax compositions comprising linear olefin dimers or hydrogenated variants thereof and methods for production thereof

Disclosed are novel supported nanoparticle compositions, precursors, processes for making supported nanoparticle compositions, processes for making catalyst compositions, and processes for converting syngas. The catalyst composition can comprise nanoparticles comprising metal oxide(s), such as manganese cobalt oxide. This disclosure is particularly useful for converting syngas via the Fischer-Tropsch reactions to make olefins and/or alcohols.
