Abstract
A process for making diesel and turbine fuels including, providing an effective amount of branched olefins, adding active heterogeneous acid catalyst(s) to said branched olefins to produce a solvent-free mixture, heating said solvent-free mixture greater than about 100° C. for a desired amount of time depending on various conditions, to produce C16 dimers/catalyst mixture, removing said catalysts from said dimers/catalyst mixture, and adding hydrogenation catalyst(s) to said dimers under hydrogen atmosphere to produce a mixture of stable fuels.

A process for making diesel/jet fuels, comprising:
- providing an effective amount of 2-ethyl-1-hexene;
- adding active heterogeneous acid catalyst(s) to said 2-ethyl-1-hexene to produce a solvent free mixture;
- heating said solvent-free mixture to greater than about 100° C. at atmospheric pressure or above for a desired amount of time depending on various conditions to selectively produce a C16 dimers/catalyst mixture;
- removing said catalyst(s) from said dimers/catalyst mixture;
- and
- adding hydrogenation catalyst(s) and hydrogenating said dimers under a hydrogen atmosphere to produce a mixture of stable diesel/jet fuels.
