Integrated Biofuel Production System
First Claim
1. A biofuel production process comprising:
- a) converting biomass to alcohol, methane, or mixtures thereof and residual biomass;
b) pyrolyzing the residual biomass to produce hydrocarbon gasses and or pyrolysis oil;
c) synthesizing a liquid hydrocarbon fuel from the alcohol, methane or mixture thereof using some of the hydrocarbon gasses or pyrolysis oil produced by pyrolyzing the residual biomass.

Abstract
According to an embodiment, a biomass conversion subsystem produces methane and/or alcohol and residual biomass. A pyrolysis or a gasification subsystem is used to produce thermal energy and/or process gasses. The thermal energy may be stored thermal energy in the form of a pyrolysis oil. A fuel conversion subsystem produces liquid hydrocarbon fuels from the methane and/or alcohol using thermal energy and/or process gasses produced by the gasification or pyrolysis subsystem. Because the biomass production system integrates the residual products from biomass conversion and the residual thermal energy from pyrolysis or gasification, the overall efficiency of the integrated biomass production system is greatly enhanced.
