What: Hawaii’s Kilauea volcano has been erupting and displaying explosive activity for more than two weeks. In one of the most recent eruptions, 1,100°C (2000°F) lava was seen gushing from multiple fissures, sending sulfur dioxide, methane gas and flames into the…
Bond Receives CAREER Award to Investigate a Niche for Biomass
Renewable, bio-based products may offer many benefits ranging from decreased greenhouse gas emissions to improved domestic energy security. However, despite growing interest in replacing fossil resources with renewable alternatives, biomass refining industries, particularly those producing biofuels, have struggled to compete with the well-established machinery of petroleum refining.
The U.S. has the capacity to sustainably harvest a considerable amount of biomass, but that quantity falls short of the amount of petroleum that is used for transportation. Biofuels have their merits, but it is unlikely that they will ever entirely replace the fossil fuels the country uses to fill its gas tanks—at least not at current rates of consumption.
While biomass may not displace fossil fuels when it comes to transportation, there are places where biomass could be competitive with fossil fuels. Crude oil is also used to synthesize reactive chemical intermediates that are used in production of solvents, plastics and polymers. Compared to traditional fuels like gasoline or diesel, these commodities are often challenging to make and relatively expensive. Often, they are easier to synthesize from biomass than they are from crude oil, giving renewable resources a competitive advantage. This could make industries dedicated to the production of bio-based chemicals possible in the near future.
An example of this type of chemical intermediate is levulinic acid, which can be prepared from sugars found in abundance in biomass. Levulinic acid can be used to produce many products that are either identical to, or functionally equivalent to, current petrochemicals.
Assistant Professor Jesse Bond of the Department of Biomedical and Chemical Engineering in the College of Engineering and Computer Science, has received the prestigious National Science Foundation (NSF) Faculty Early Career Development (CAREER) award to further explore levulinic acid’s applications. His work will support development of catalysts and cost-effective technologies that facilitate oxidation of levulinic acid to deliver value-added chemical products.
“My immediate hope is that this research pushes a technology forward that has a positive net impact on sustainability,” Bond says. “Beyond that, my ultimate goal is to teach our students about major problems facing society and the ways that chemical engineering and catalysis can address those problems. No matter where this research leads or how the biotechnology landscape unfolds, catalysis will always have a role in making useful products from available natural resources.”
“Through this work, we are gaining fundamental knowledge about catalytic reactions, and those insights are generally universal. If I have trained my students to think rigorously about governing principles, to ask questions of fundamental importance, and to design experiments that answer those questions—I think those are the most important things that can come from their education.”
