Development of Catalysts for the Selective Conversion of Biomass Derived Products to Fuels
EMSL Project ID
47660
Abstract
The large increase in energy demand by emerging economies and the environmental concerns over the use of fossil fuels has led to the focus on renewable energy sources such as biomass. Several thermochemical processes for the conversion of biomass to fuels or chemicals such as fast pyrolysis, liquefaction, gasification or hydrolysis, are being currently investigated 1. These processes share one thing in common, their products need upgrading, either through hydrodeoxygenation or Fischer-Tropsch synthesis, which requires the selective C-O bond cleavage. In order to design catalysts for the selective conversion of biomass to fuels, a fundamental understanding of the catalyst structure and its relation to the cleavage of C-O vs. C-C or C-H bonds is crucial. The goal of this research is to combine theoretical and experimental investigation of the catalyst structure (metal type, oxidation state and particle size) and its effect on the selectivity for C-O, C-C and C-H bond cleavage. The fundamental understanding of the catalyst structure effect on reaction mechanism will guide the rational synthesis of catalysts for the selective conversion of biomass to fuels. The focus of the proposed work is catalyst development for lignocellulosic sugars conversion to bio-fuels by aqueous phase reforming/upgrading.
