Work History
Graduate Research Assistant
University of Utah
Salt Lake City, United States
08.2020 - Current
- Designed and demonstrated Drop-Tube Reactor for experimental study of zinc ferrite formation in steel making off-gas cleaning systems, achieving specific testing conditions and determining its unfavorable formation range for potential implementation of in-process separation technology
- Performed thermodynamic and kinetic calculations, data analysis, and powder characterization to find kinetic model, accounting for the temperature, particle residence time, and partial pressure effects on fluid-solid reactions
- Managed safe operation of high-temperature reactor along with powder and gas supplies using comprehensive safety protocols
- Participated in regular meetings with project supervisors, providing progress updates and discussing potential challenges or areas for improvement.
