Abstract

Increasing global energy demands have driven research in both alternative renewable energy supplies and synthesis of commodity chemicals from bio-based feedstocks. The adsorption of glycerol, lactic acid, propanoic acid, and their hydrogenolysis products into activated carbon supports, was studied to characterize local concentrations in the catalyst pores and eventually incorporating local pore concentration into kinetic modeling and reactor design of hydrogenolysis. The use of activated carbon-supported catalysts for aqueous phase catalytic conversion of biorenewable, water-soluble substrates led to local enhancement in pore concentration of reactant and product species. Organic species with only modestly different structures demonstrated different affinities for adsorption in activated carbon; this difference in affinity had a strong effect on the observed rate of reactivity of the species over carbon-supported catalysts. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
