Abstract
A process and system for separating bio-gasoline, bio-diesel and bio-fuel oil fractions from a bio-oil, and for producing a renewable gasoline including at least in part the bio-gasoline fraction, is provided. The process comprises separating bio-oil into a bio-gasoline fraction and a heavy fraction based on their boiling points. At least a portion of the bio-gasoline fraction is directly blended with a petroleum-derived gasoline, without any prior hydrotreatment, to thereby provide a renewable gasoline composition.
Claims23
A process for producing a bio-gasoline fraction, said process comprising:
- (a) converting biomass in a conversion reactor containing a catalyst to thereby produce a conversion reactor effluent comprising vapor conversion products;
- (b) condensing at least a portion of said vapor conversion products to thereby provide a bio-oil having a total oxygen content of less than 15 weight percent;
- and
- (c) separating said bio-oil by distillation into at least a bio-gasoline fraction and a heavy fraction, wherein at least 75 weight percent of said bio-gasoline fraction has a boiling point less than 205° C., and wherein at least 75 weight percent of said heavy fraction has a boiling point greater than 205° C.
A process for producing a renewable gasoline composition, said process comprising:
- (a) separating a bio-oil into at least a bio-gasoline fraction and a heavy fraction, wherein at least 75 weight percent of said bio-gasoline fraction has a boiling point less than 205° C., wherein at least 75 weight percent of said heavy fraction has a boiling point greater than 205° C., wherein said bio-oil has not previously been subjected to an oxygen-removing hydrotreatment step, wherein said bio-oil has a total oxygen content of less than 15 weight percent;
- and
- (b) combining at least a portion of said bio-gasoline fraction with a petroleum-derived gasoline to thereby produce a renewable gasoline composition, wherein said renewable gasoline composition comprises said petroleum-derived gasoline in an amount of at least 80 weight percent and said bio-gasoline fraction in an amount greater than 0.1 and less than 20 weight percent.
