Non Technical Summary
The United States has a huge trade deficit to purchase petroleum for transportation fuels. These costs (deficit) are increasing as crude oil becomes more difficult to find and collect, and these payments often fund countries antagonistic to the US interests. Converting waste biomass to liquid hydrocarbons offers an alternative source of transportation fuels. Research in this problem area is concerned with advancing the forest biorefinery for production of transportation fuels and higher valued chemicals that can reduce demand for fossil fuels. It includes chemical and biological conversion methods such as saccharification and fermentation, and thermochemical methods such as pyrolysis with chemical production from the product gas or pyrolysis oil. Specific research concerns are that wood is harder to convert to sugars than biomass from annual plants and needs specialized pretreatment methods. The unit is researching specific methods that use sulfurous acid as the pretreatment chemical since this prepares softwood biomass effectively for enzyme saccharification. The unit is also researching methods to integrate bio-fuels effectively within the existing forest products industries, rather than as a direct competitor for biomass to existing valued uses including paper, particleboard, and lumber.


Objectives Summary
Identify cost effective methods to convert wood-carbohydrates to sugars, and derive higher value from other wood components including lignin and extractives.


Approach Summary
Methods Not Available.
