WSU researcher develop catalysts converting ethanol into isobutene

In Washington state, Washington State University researchers have developed a catalyst that easily converts bio-based ethanol to a widely used industrial chemical, paving the way for more environmentally friendly, bio-based plastics and products.

The researchers have published a paper online describing the catalyst in the Journal of the American Chemical Society (http://pubs.acs.org/doi/abs/10.1021/jacs.5b07401) and have been granted a U.S. patent.

In collaboration with the Archer Daniels Midland (ADM) Company, researchers developed a catalyst to convert bio-based ethanol, which is made from corn or other biomass, to isobutene in one easy production step.

The researchers examined the costs and lifetime of their catalyst to determine its practicality for the marketplace and determined that it could be used for other closely related feedstocks. They also discovered just how their catalyst works, knowledge that could be used to design more efficient catalysts for a wide range of applications.

In addition to ADM, the work was supported by a grant from the Department of Energy (DE-AC05-RL01830, FWP-47319).
