Abstract Cellulosic biomass can be directly converted to hydrocarbon transportation fuels through the use of hydropyrolysis or integrated plus hydroconversion (IH 2 ). Hydropyrolysis performed in a fast fluidized bed under 14–35 bar hydrogen pressure with an effective deoxygenation catalyst produces fungible product less than 1 total acid number which either fed refinery polished reactor produce gasoline and diesel 1% oxygen. Experimental data from 0.45 kg/h semi‐continuous IH pilot plant is presented. Economics life cycle analysis will presented later this series, show that by employing technology, at delivered costs some cases significantly $1.80/gallon greater 90% reduction greenhouse gas emissions. Larger (2.08 kg/h) long‐term continuous pilot‐scale testing process commence near future. As biomass‐to‐fuels conversion has potential substantially reduce US dependence on foreign oil, thereby reducing price lowering worldwide © American Institute Chemical Engineers Environ Prog, 2011
