Abstract
A process for upgrading at least one of a Fischer-Tropsch naphtha and a Fischer-Tropsch distillate to produce at least one of a gasoline component, a distillate fuel or a lube base feedstock component. The process includes reforming a Fischer-Tropsch naphtha to produce hydrogen by-product and a gasoline component with a research octane rating of at least about 80. The process further includes upgrading a Fischer-Tropsch distillate using the hydrogen by-product to produce a distillate fuel and/or a lube base feedstock component.
Claims20
A plant for upgrading at least one of a Fischer-Tropsch naphtha and a Fischer-Tropsch distillate to produce at least one of a gasoline component, a distillate fuel or a lube base feedstock component, said plant comprising:
- a) a hydrocarbon source providing a hydrocarbon;
- b) a separator that separates hydrocarbon gas, hydrocarbon condensate and crude oil from the hydrocarbon;
- c) a synthesis gas generator that generates a synthesis gas from the hydrocarbon gas, said synthesis gas generator positioned downstream from said separator;
- d) a Fischer-Tropsch reactor positioned downstream from said synthesis gas generator that conducts a Fischer-Tropsch process on the synthesis gas to obtain a Fischer-Tropsch naphtha and a Fischer-Tropsch distillate;
- e) a naphtha hydrotreatment reactor positioned downstream from said Fischer-Tropsch reactor that hydrotreats the Fischer-Tropsch naphtha produced from said Fischer-Tropsch reactor;
- f) a naphtha reformer positioned downstream from said naphtha hydrotreatment reactor that reforms hydrotreated naphtha produced from said naphtha hydrotreatment reactor to obtain hydrogen by-product and a gasoline component comprising at least about 10% aromatics;
- g) a distillate hydrotreatment reactor positioned downstream from said Fischer-Tropsch reactor that hydrotreats the Fischer-Tropsch distillate produced from said Fischer-Tropsch reactor;
- and
- h) a distillate upgrader positioned downstream from said distillate hydrotreatment reactor and relative to said naphtha reformer so that the hydrogen by-product from said reformer recirculates to said upgrader so that said upgrader can upgrade hydrotreated distillate produced from said distillate hydrotreatment reactor to produce a distillate fuel and/or a lube base feedstock component.
