Abstract:
1. A method for upgrading a petroleum-derived hydrocarbonaceous fraction by at least reducing its density, comprising: (A) providing the petroleum-derived hydrocarbonaceous fraction comprising a light cycle oil, a heavy cycle oil, a bunker fuel, a vacuum gas oil, a heating oil, or any combination of two or more thereof; (B) providing a synthetically-derived hydrocarbonaceous fraction, wherein the synthetically-derived hydrocarbonaceous fraction is derived from synthesis gas and has been hydrotreated to convert substantially all of its unsaturated hydrocarbons and oxygenates to saturated hydrocarbons, and further wherein the petroleum-derived hydrocarbonaceous fraction has a density at 15° C. of at least about 60 kg/m (C) blending said petroleum-derived hydrocarbonaceous fraction with an effective amount of synthetically-derived hydrocarbonaceous fraction to reduce the density of said petroleum-derived hydrocarbonaceous fraction to form a blend suitable for use as a diesel or diesel blendstock, wherein the blend has a density at 15° C. between about 800 kg/m
