摘要： Methyl paraffins formed by hydrogenating one or more LAO dimers comprising a vinylidene moiety or a trisubstituted olefin moiety may have advantageous heat transfer properties, particularly when incorporated within an electric vehicle. For example, methyl paraffins produced upon hydrogenating LAO dimers formed from one or more C6-C12 LAOs, particularly in the presence of a Hf metallocene catalyst system, may contain 12-24 carbon atoms, and collectively have a flash point of about 130°C or above, a pour point of about -42°C or lower, a thermal conductivity at 80°C of about 0.165W/m·K or higher, and a Mouromtseff number ranging from about 17,000 to about 27,000 kg/(s2.2 ·m0.6·K) at 80°C. Heat transfer fluids comprising such methyl paraffins may be placed in contact with a heat-generating component, such as a battery and/or motor of an electric vehicle, or within a similar type of battery system, including immersive configurations for a battery.

摘要： Methylparaffins having limited methyl branching may be prepared by contacting at least one linear olefin with hydrogen in the presence of a dual-function supported catalyst comprising a solid acid component and a hydrogenation component under conditions sufficient to catalytically isomerize the at least one linear olefin into an intermediate product comprising one or more branched olefins, and hydrogenating the one or more branched olefins to form an isoparaffin product comprising one or more methylparaffins. Heat transfer fluids comprising such methylparaffins may be used in various thermal management systems, such as within various systems of electric vehicles, server farms, or other locales in need of efficient heat transfer.

摘要： Processes are described for isomerizing one or more C 14 -C 24 alpha olefins to produce an isomerization mixture comprising one or more C 14 -C 24 internal olefins comprising contacting an olefinic feed comprising the one or more C 14 -C 24 alpha 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 pomt with maintained hiodegradabiiity properties as compared to the olefinic feed, and is particularly useful in drilling fluid and paper sizing compositions.
