Process development is underway on technology for catalytic hydrogenation for converting biomass fast pyrolysis oils to upgraded liquid fuels and chemicals. Experimental work includes small batch reactor tests with several bio-oils and chemical model compounds to better understand catalyst deactivation and hydrogenation pathways with new catalyst formulations and processing conditions. Product analysis using both gas chromatography (with mass spectrometry and flame ionization detector) and nuclear magnetic resonance for identifying and quantifying the components, and determining the compositions of the products, respectively, are presented. Operations in a bench-scale continuous-flow hydrotreater are also presented. Processing tests were completed with bio-oil samples received from the bio-oil producers cooperating with this project. Analyses of the products, as well as mass balance calculations, are described.
