Abstract
A biofuel composition and a process for the manufacture of a biofuel composition including lignin and ethanol as the main combustible components of the biofuel composition and having total ash below 1% w/w based on total mass of dry matter in the biofuel composition.
Claims25
A process for the manufacture of a biofuel composition comprising processed lignin and ethanol as its main combustible components having total ash below 1% w/w based on total mass of dry matter in said biofuel composition, said process comprising:
- i. providing a slurry comprising ethanol and a biomass comprising lignin as its main combustible component;
- ii. subjecting said slurry to an organosolv extraction at an extraction temperature T1 from 100° C. to 250° C., at an extraction pressure P1 from 10 bar to 60 bar, and for an extraction time t1 not exceeding 24 hours, thereby providing a resulting slurry and a precipitate;
- iv. separating said resulting slurry of step ii. from said precipitate;
- and
- vi. cooling said resulting slurry of step iv. to obtain said biofuel composition.
A biofuel composition comprising:
- ethanol;
- and
- processed lignin solubilized and/or dispersed in said ethanol as main combustible mass fractions and comprising not more than 1% w/w of ashes based on total dry mass of said biofuel composition.
A biofuel composition comprising a biofuel comprising processed lignin and ethanol as its main combustible components having total ash below 1% w/w based on total mass of dry matter in said biofuel composition, wherein said biofuel is obtained by a process comprising:
- i. providing a slurry comprising ethanol and a biomass comprising lignin as its main combustible component;
- ii. subjecting said slurry to an organosolv extraction at an extraction temperature T1 from 100° C. to 250° C., at an extraction pressure P1 from 10 bar to 60 bar, and for an extraction time t1 not exceeding 24 hours, thereby providing a resulting slurry and a precipitate
- iv. separating said resulting slurry of step ii. from said precipitate;
- and
- vi. cooling said resulting slurry of step iv. to obtain said biofuel composition.
