Abstract
A process and system for separating and upgrading bio-oil into renewable fuels is provided. The process comprises separating bio-oil into a light fraction and heavy fraction based on their boiling points. The heavy fraction is then subjected to hydrotreatment, while the light fraction is not subjected to hydrotreatment. At least a portion of the un-hydrotreated light fraction and at least a portion of the hydrotreated heavy fraction are blended with petroleum-derived gasoline to thereby provide a renewable gasoline, and at least a portion of the hydrotreated heavy fraction is blended with petroleum-derived diesel to thereby provide a renewable diesel.
Claims20
A system for producing a bio-oil, said system comprising:
- a biomass feedstock source for providing solid particulate biomass;
- a conversion reactor for thermally converting said solid particulate biomass into a bio-oil;
- a separator for separating said bio-oil into at least a bio-gasoline fraction and a bio-distillate fraction;
- a hydrotreater for hydrotreating said bio-distillate fraction to thereby produce a hydrotreated product;
- a fractionator for fractionating said hydrotreated product into at least a hydrotreated bio-gasoline and a hydrotreated bio-diesel;
- a petroleum-derived gasoline source for providing a petroleum-derived gasoline;
- a gasoline blending system for combining at least a portion of said bio-gasoline fraction and at least a portion of said hydrotreated bio-gasoline with said petroleum-derived gasoline;
- a petroleum-derived diesel source for providing a petroleum-derived diesel;
- and
- a diesel blending system for combining at least a portion of said hydrotreated bio-diesel with said petroleum-derived diesel.
A system for producing one or more renewable fuels, said system comprising:
- a biomass feedstock source for providing solid particulate biomass;
- a conversion reactor for thermally converting said solid particulate biomass into a bio-oil;
- a separation system for separating said bio-oil into one or more bio-gasoline fractions and one or more bio-distillate fractions;
- a petroleum-derived gasoline source for providing a petroleum-derived gasoline;
- a first blending system for combining at least one of said bio-gasoline fractions with said petroleum-derived gasoline;
- one or more petroleum-derived distillate sources for providing one or more petroleum-derived distillates;
- a second blending system for combining at least one of said bio-distillate fractions with at least one of said petroleum-derived distillates;
- and
- a hydrotreater for (i) hydrotreating at least one of said bio-gasoline fractions prior to combination with said petroleum-derived gasoline in said first blending system and/or (ii) hydrotreating least one of said bio-distillate fractions prior to combination with at least one of said petroleum-derived distillates in said second blending system.
The system of claim 20, wherein said fractionator is operable to produce at least one of said bio-gasoline fractions, wherein said at least one bio-gasoline fraction produced by said fractionator is combined with said petroleum-derived gasoline in said first blending zone.
