摘要:
A diesel engine fuel is produced from Fischer-Tropsch wax by separating a light density fraction, e.g., C.sub.5 -C.sub.15, preferably C.sub.7 -C.sub.14 cut having at least 80+ wt % n-paraffins, no more than 5000 ppm alcohols as oxygen, less than 10 wt % olefins, twice aromatics and very low sulfur and nitrogen.

Diesel fuels or blending stocks having excellent lubricity, oxidative stability and high cetane number are produced from non-shifting Fischer-Tropsch processes by separating the Fischer-Tropsch product into a lighter and heavier fractions, e.g., at about 700° F., subjecting the 700° F.+ fraction to hydro-treating, and combining the 700° F.− portion of the hydrotreated product with the lighter fraction that has not been hydrotreated.

摘要:
A process for the production of a winter diesel fuel from wax containing hydrocarbons produced by the Fischer-Tropsch hydrocarbon synthesis process. A 300° F.+ Fischer-Tropsch fraction is upgraded first by hydroisomerization followed by catalytic dewaxing resulting in a diesel fuel suitable for use as a winter diesel fuel having excellent cold flow properties and reduced emissions.
摘要:
A wide cut Fischer-Tropsch derived diesel fuel is produced wherein the distillate boils in a wider range than a conventional diesel fuel while providing favorable low temperature properties and environmentally beneficial effects. In particular, the fuel comprises a hydrocarbon distillate derived from the Fischer-Tropsch process having T90 greater than 640° F. (338° C.) but less than 1000° F. (538° C.) and a cold filter plugging point less than or equal to +5° C.
摘要:
A blended fuel, useful as a diesel fuel, wherein the fuel blend contains an undercut conventional diesel fuel, blended with a Fischer-Tropsch derived diesel fuel, such that the blend demonstrates better than expected emissions and a reduced sulfur content. In particular, the blend is an asymmetric diesel fuel blend comprising a Fischer-Tropsch derived hydrocarbon distillate having a T95 of at least 600° F., blended with a petroleum derived hydrocarbon distillate having an initial boiling point and a T95 no greater than 640° F.
摘要:
The instant invention is directed to an integrated process for producing a hydroisomerate in the presence of sulfur comprising the steps of (a) separating a natural gas into a first stream comprising a C.sub.5 + gas field condensate containing sulfur and a second stream comprising said natural gas having said a C.sub.5 + gas field condensate removed therefrom, (b) removing sulfur from said second stream, (c) subjecting said second stream to a synthesis gas generation process to produce synthesis gas; (d) subjecting said synthesis gas to a hydrocarbon synthesis process to produce hydrocarbons, (e) hydrotreating and hydroisomerizing said hydrocarbons of step (d) in the presence of said first stream over a catalyst having an acidic functionality and comprising a Group VIII non-noble metal or tungsten and a hydrocracking suppressant, wherein said hydrocracking suppressant is selected from the group consisting of Group IB metal, sulfur and mixtures thereof, and wherein when said hydrocracking suppressant is sulfur, said acidic functionality is an amorphous refractory oxide.
