ABSTRACT:
The invention includes a process for producing synthetic middle distillates and synthetic middle distillates produced therefrom. In one embodiment, the process comprises fractionating a hydrocarbon synthesis product to at least generate a light middle distillate, a heavy middle distillate, and a waxy fraction; thermally cracking the waxy fraction; and isomerizing the heavy middle distillate. A synthetic diesel or blending component is formed by the combination of at least a portion of the light middle distillate; at least a portion or fraction of the thermally cracked product; and at least a portion or fraction of the isomerized product. In some embodiments, the hydrocarbon synthesis product and/or the thermally cracked product may be hydrotreated. In other embodiments, a synthetic middle distillate comprises at least two fractions: a light fraction with not more than 10% branched hydrocarbons, and a heavy fraction with at least 30% branched hydrocarbons.
