Abstract
Liquid bio-fuels and processes for their production are provided. The liquid bio-fuels can have improved stability, less corrosiveness, and/or an improved heating value.
Claims33
A liquid bio-fuel comprising:
- 50 to 95 weight percent oxygenated hydrocarbons;
- 5 to 50 weight percent nonoxygenated hydrocarbons;
- not more than 15 weight percent water;
- and not more than 2,500 ppmw solids, wherein said liquid bio-fuel has an ignition temperature in the range of 175 to 300° C. and a higher heating value at least 9,000 btu/lb.
1 more element
A liquid bio-fuel composition comprising:
- oxygenated hydrocarbons in an amount such that said bio-fuel has an oxygen content of less than 30 weight percent;
- and nonoxygenated hydrocarbons having an aromatic content greater than 40 weight percent, wherein the high heating value of said bio-fuel is greater than 10,000 btu/lb., wherein said bio-fuel has a stability parameter of less than 30 cP/h, wherein cP/h is viscosity in units of centipoise per hour.
A method of operating a fuel-powered device, said method comprising:
- (a) combusting a petroleum-derived fuel in a fuel-powered device to thereby produce thermal and/or mechanical energy;
- and
- (b) combusting a biomass-derived fuel in said fuel-powered device to thereby produce thermal and/or mechanical energy,
- wherein said fuel-powered device is not mechanically modified to account for the fuel change between steps (a) and (b),
- wherein said biomass-derived fuel is produced via pyrolysis of biomass, wherein said bios mass-derived fuel comprises a liquid bio-fuel comprising 50 to 95 weight percent oxygenated hydrocarbons, 5 to 50 weight percent nonoxygenated hydrocarbons, not more than 15 weight percent water, and not more than 2,500 ppmw solids, wherein said liquid bio-fuel has an ignition temperature in the range of 175 to 300° C. and higher heating value at least 9,000 btu/lb.
