biofuels

Using equipment that captures and measures exhaust, the researchers tested biofuels in the same type of engine used by a Boeing 737.

Mixing alternative fuels with conventional jet fuel can cut aircraft emissions by nearly 40 percent, says Prem Lobo, MS ChE’03, MS EMgt’05. And it doesn’t affect engine performance.

In a study published in the journal Environmental Science and Technology, Lobo and his fellow Missouri S&T researchers tested two types of alternative jet fuels: biofuels made from vegetable oils, and fuels made with the Fischer-Tropsch process, which creates liquid hydrocarbons from coal, natural gas or biomass. Using equipment that captures and measures exhaust, the researchers tested the fuels in the same type of engine used by a Boeing 737, measuring at different power levels to simulate an airplane’s taxi, takeoff, climb and descent.
They found that the more alternative fuel they blended with the jet fuel, the lower the particulate matter emissions. But they also discovered that the only fuel that was a viable alternative was a 50-50 blend of Fischer-Tropsch fuel and jet fuel. It maintained adequate engine power for commercial or military use and it reduced particulate matter mass emissions by 39 percent.
Lobo, assistant director of the S&T Center of Excellence for Aerospace Particulate Emissions Reduction Research, was the lead author of the Environmental Science and Technology paper. Co-authors were Philip Whitefield, interim vice provost for academic affairs, professor of chemistry and director of the center, and Donald Hagen, professor of physics and a researcher at the center.

Making tornado alley safer

Growing up in northeast China, Guirong “Grace” Yan didn’t see many tornados in a country where the number of documented twisters is a fraction of those that hit the United States. But as her academic career took Yan to several postdoctoral fellowships and then faculty positions in Indiana, Missouri and Texas, the assistant professor of […]

Partners for progress

An expansion of the partnership between Missouri S&T and Missouri State University will allow students to pursue a mechanical engineering degree on the Missouri State campus with courses taught by faculty from both institutions. Students began applying this fall. The program will begin in fall 2019.
