A method for isomerizing alpha olefins to produce an isomerization mixture comprising branched olefins can comprise contacting an olefinic feed including one or more C-Calpha olefins with a catalyst under skeletal isomerization conditions, wherein the catalyst comprises a molecular sieve having an MRE topology; and obtaining an isomerization mixture comprising one or more C-Cbranched olefins.

Methods for isomerizing alpha olefins

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

Compositions can include mixtures having from about 2 wt % to about 40 wt % of C-Clinear paraffins based on the weight of the mixture, from about 60 wt % to about 98 wt % of C-Cbranched saturated hydrocarbons based on the weight of the mixture, and less than or equal to about 30 wt % of Csaturated hydrocarbons based on the weight of the mixture. Methods to obtain these compositions can include the isomerization of one or more C-Calpha olefins under skeletal isomerization conditions to obtain an isomerization mixture and the hydrotreating of the isomerization mixture.
