Catalyst lifetime has a significant impact on economics of biomass conversion processes. However, there are unique challenges to developing catalysts with long lifetime for bioenergy applications due to the unique qualities of biomass (e.g., high oxygen content, high moisture content, highly reactive functional groups) which causes certain problematic catalyst deactivation. These deactivation issues are unique and not well studied because most of current knowledge on catalyst deactivation is on petroleum-based conversion technologies.  This presentation will provide 1) a brief overview of the enabling project “Catalyst Deactivation Mitigation for Biomass Conversion “of Chemical Catalysis for Bioenergy Consortium (ChemCatBio); 2) a preliminary established correlation of feedstock properties and catalyst functionalities with catalyst deactivation and mitigation approaches; 3) several examples relevant to catalyst deactivation and mitigation in our recent catalyst and process development efforts for biomass conversion, including but not limited to aqueous phase alcohol dehydration over zeolite, hydrogenation of fast pyrolysis bio-oil, and aqueous phase conversion carboxylic acid for C-C coupling.<br/>
