Abstract
A method for processing biomass to produce biofuel includes decomposing lignocellulosic material into byproduct polymers that include lignin, decomposing the lignin into targeted chemical fragments, and chemically converting the targeted chemical fragments into a biofuel.
Claims18
A method for processing biomass to produce biofuel, the method comprising:
- decomposing lignocellulosic material into byproduct polymers that include lignin;
- decomposing the lignin into targeted chemical fragments that include oxygenates;
- and
- chemically converting the targeted chemical fragments by reacting the targeted chemical fragments with each other to produce biofuel hydrocarbons having from 9 to 16 carbon atoms.

A method for processing biomass, the method comprising:
- decomposing lignocellulosic material into byproduct polymers that include lignin;
- decomposing the lignin into short-chain hydrocarbon fragments having 9 carbon atoms or less;
- and
- chemically converting the short-chain hydrocarbon fragments into a biofuel that includes hydrocarbons having from 9 to 16 carbon atoms by reacting the short-chain hydrocarbon fragments with each other.
