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 process for upgrading a Fischer-Tropsch naphtha to produce a gasoline component, the process comprising:
- a) hydrotreating a Fischer-Tropsch naphtha to remove oxygenates producing hydrotreated Fischer-Tropsch naphtha;
- b) reforming said hydrotreated Fischer-Tropsch naphtha producing hydrogen by-product and a gasoline component having a research octane rating of at least about 80;
- and
- c) recirculating said hydrogen by-product to hydrotreat said Fischer-Tropsch naphtha.
A process for upgrading a Fischer-Tropsch naphtha to produce a gasoline component, the process comprising:
- a) hydrotreating a Fischer-Tropsch naphtha, using a catalyst comprising at least one of a noble metal and a non-noble metal, producing hydrogen by-product and a gasoline component having a research octane rating of at least about 90 and comprising at least about 10% aromatics;
- and
- b) recirculating said hydrogen by-product to hydrotreat said Fischer-Tropsch naphtha.
A process for upgrading a Fischer-Tropsch naphtha to produce a gasoline component, the process comprising:
- a) hydrotreating a Fischer-Tropsch naphtha to remove oxygenates producing hydrotreated Fischer-Tropsch naphtha;
- b) reforming said hydrotreated Fischer-Tropsch naphtha producing hydrogen by-product and a gasoline component having a research octane rating of at least about 80;
- and
- c) recirculating said hydrogen by-product to hydrotreat said Fischer-Tropsch naphtha;
- d) wherein said Fischer-Tropsch naphtha is a blended naphtha, having a sulfur level of at least about 1 ppm, obtained by mixing said Fischer-Tropsch naphtha with a petroleum-derived naphtha.
