Abstract

Biomass-derived hydrocarbons that include gasoline, diesel, and jet fuel will help replace finite fossil fuel hydrocarbons of the same range. This study showed that temperature could be controlled in a scaled-up reactor system using three types of syngas. The CO conversion, selectivity and amount of product created from each type of syngas were examined. Clean syngas composed of 40% H2, 20% CO, 12% CO2, 2% CH4, and 26 % N2 was used to test ideal stoichiometric molar values. Clean syngas composed of 19% H2, 20% CO, 12% CO2, 2% CH4, and 47 % N2 was used to test an ideal contaminateree synthesis gas situation to mimic our particular downdraft gasifier. Gasifier wood syngas composed of 19% H2, 20% CO, 12% CO2, 2% CH4, 46 % N2, and 1% O2 was used in this study to determine the feasibility of using gasified biomass syngas to produce gasolinerange hydrocarbons.
