Liquid Fuels by Low-Severity Hydrotreating of Biocrude

摘要: Bio crude (fast pyrolysis oil from wood) was hydrotreated to minimize the negative aspects of this fuel. The instability reduced by reaction most unstable functional groups. Concurrently, oxygenated component also reduced, resulting in an improved energy density. Changes physical handling properties were modified. All change accomplished at less severe processing conditions (lower temperature, shorter residence time) than that required for earlier gasoline production. Improved conversion achieved use a downflow reactor system. experiments reported include those performed with clean (filtered hot vapor) biocrude just recently available systems U.S.
