Abstract
This invention relates to a process, a plant, and a biofuel for integrated biofuel production, such as with butanol, biodiesel, and/or sugar product. The integrated process includes the step of removing hexose from a feedstock to form a lignocellulosic material. The process also includes the step of converting the hexose to butanol and/or a biodiesel material, and the step of depolymerizing lignocellulosic material to form pentose and a residue. The process also includes the step of converting the pentose to butanol and/or a biodiesel material.
Claims28
An integrated process of coproducing butanol and biodiesel, the process comprising:
- removing hexose from a feedstock to form a lignocellulosic material;
- converting the hexose to butanol;
- depolymerizing the lignocellulosic material to form pentose and a residue;
- and
- converting the pentose to a biodiesel material.
An integrated process of coproducing butanol and biodiesel, the process comprising:
- removing hexose from sugarcane to form a lignocellulosic material;
- converting the hexose to butanol;
- depolymerizing the lignocellulosic material to form pentose and a residue;
- converting the pentose to a biodiesel material;
- consuming the residue to produce energy;
- reacting the biodiesel material with methanol to form a biodiesel product and glycerin;
- and
- converting the glycerin to additional biodiesel material;
- wherein the process produces a mass ratio of biodiesel to butanol of at least about 0.2 kilotons of biodiesel to 1.0 kiloton of butanol.
An integrated butanol and biodiesel plant, the plant comprising:
- a hexose removal unit adapted for removing hexose from a feedstock to form a lignocellulosic material;
- a hexose conversion unit adapted for converting hexose to butanol;
- a pentose depolymerization unit adapted for removing pentose from the lignocellulosic material to form a residue;
- and
- a pentose conversion unit adapted for converting pentose to a biodiesel material.
An integrated process of coproducing biofuels, the process comprising:
- removing hexose from a feedstock to form a lignocellulosic material;
- converting the hexose to butanol or a biodiesel material;
- depolymerizing the lignocellulosic material to form pentose and a residue;
- and
- converting the pentose to butanol or a biodiesel material.
