The document discusses a process called Integrated Hydropyrolysis and Hydroconversion (IH2) that can directly produce drop-in gasoline and diesel fuels from biomass. IH2 uses catalytic hydropyrolysis and hydroconversion to remove oxygen from biomass and upgrade the resulting products into cellulosic hydrocarbon fuels. The process is designed to use a variety of feedstocks in a cost-effective manner and produce fuels with minimal environmental impact.
