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.

Branched paraffinic compositions derived from isomerized and hydrogenated linear alpha olefins

Processes are described for isomerizing one or more C-Calpha olefins to produce an isomerization mixture comprising one or more C-Cinternal olefins comprising contacting an olefinic feed comprising the one or more C-Calpha olefins with a catalyst under isomerization conditions, wherein the catalyst comprises a microporous crystalline aluminosilicate having an MWW framework. The resulting isomerization mixture typically exhibits a low pour point with maintained biodegradability properties as compared to the olefinic feed, and is particularly useful in drilling fluid and paper sizing compositions.
