Abstract
A process and system for separating a light fraction, a bio-distillate fraction, and a heavy fraction from a bio-oil, and for producing a renewable distillate including at least in part the bio-distillate fraction and a stabilizing additive, is provided. The process comprises separating bio-oil into light, bio-distillate, and heavy fractions based on their boiling points. At least a portion of the bio-distillate fraction and a stabilizing additive are blended with a petroleum-derived-diesel-range stream, without any prior hydrotreatment, to thereby provide a renewable distillate composition.
Claims19
A process for producing a bio-distillate 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 portion of said vapor conversion products to thereby provide a bio-oil having a total oxygen content of less than about 15 weight percent;
- and
- (c) separating a bio-distillate fraction from said bio-oil, wherein at least about 75 weight percent of said bio-distillate fraction has a boiling point between about 180° C. and about 380° C., and wherein said bio-distillate fraction comprises at least about 50 weight percent oxygen-free hydrocarbons.
A process for producing a renewable distillate, said process comprising:
- (a) separating a bio-oil into at least a bio-distillate fraction, wherein at least about 75 weight percent of said bio-distillate fraction has a boiling point between about 180° C. and about 380° C., wherein said bio-oil has a total oxygen content of less than about 15 weight percent and wherein said bio-oil has not previously been subjected to an oxygen-removing hydrotreatment step;
- and
- (b) combining at least a portion of said bio-distillate fraction with a petroleum-derived- distillate-range stream, and a stabilizing additive having surfactant properties, to thereby produce a renewable distillate having a single clear phase, wherein said renewable distillate comprises said petroleum-derived-distillate-range stream in an amount of between about 5 weight percent and about 99 weight percent, said bio-distillate fraction in an amount of at least about 0.5 weight percent, and said stabilizing additive in an amount between about 0.5 and about 25 weight percent.
A process for producing a renewable distillate, said process comprising:
- (a) separating a bio-oil into at least a bio-distillate fraction, wherein at least about 75 weight percent of said bio-distillate fraction has a boiling point between about 180° C. and about 380° C., wherein said bio-oil has not previously been subjected to an oxygen-removing hydrotreatment step;
- and
- (b) combining at least a portion of said bio-distillate fraction with a petroleum-derived- distillate-range stream, and a stabilizing additive having surfactant properties, to thereby produce a renewable distillate having a single clear phase, wherein said renewable distillate comprises said petroleum-derived-distillate-range stream in an amount of between about 5 weight percent and about 99 weight percent, said bio-distillate fraction in an amount of at least about 0.5 weight percent, and said stabilizing additive in an amount between about 0.5 and about 25 weight percent, wherein said stabilizing additive is FAME.
