Abstract
This invention relates to a process, a plant, and a biofuel for integrated biofuel production, such as with biogasoline, 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 a biogasoline 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 a biogasoline and/or a biodiesel material.
Claims27
An integrated process of coproducing biofuels, the process comprising:
- removing hexose from a feedstock to form a lignocellulosic material;
- converting the hexose to a biogasoline;
- depolymerizing the lignocellulosic material to form pentose and a residue;
- and
- converting the pentose to a biodiesel material.
An integrated process of coproducing biofuels, the process comprising:
- removing hexose from sugarcane to form a lignocellulosic material;
- converting the hexose to biogasoline;
- 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 biogasoline of at least about 0.2 kilotons of biodiesel to 1.0 kiloton of biogasoline.
An integrated biofuels 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 a biogasoline;
- 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 sugar product and biofuel, the process comprising:
- removing hexose from a feedstock and to form a lignocellulosic material;
- converting the hexose to a sugar product;
- depolymerizing the lignocellulosic material to form pentose and a residue;
- and
- converting the pentose to a biogasoline or a biodiesel material.
