Advanced Characterization of a Ag/ZrO2/SiO2 Catalyst for the Conversion of Bio-derived Ethanol to Butadiene


EMSL Project ID
50119

Abstract

The overall objective of this study is to further investigate a recent catalyst innovation enabling the selective, single step conversion of bio-derived ethanol to butadiene. We intend to advance the technology through new catalyst concepts and better understand the mechanism through advanced characterizations. We aim to do this by addressing the following two areas:
1) Understand the nature of the Ag catalytic component that facilitates the initial hydrogenation of ethanol to acetaldehyde reaction.
2) Perform catalyst characterization of the ZrO2/SiO2 catalyst to gain fundamental understanding of the catalytic structure thus selectively enabling the acetaldehyde condensation reaction that is rate-limiting.
