Siyun is currently a PhD student from the School of Chemical Engineering and Advanced Materials at the University of Adelaide, supervised by Dr. Woei Saw. She is also one of HILT CRC’s HDR students. Her current research project is about replacing natural gas combustion with H₂ combustion or electrification in alumina calcination process to achieve CO₂ mitigation, pure steam recovery and energy saving. The project also includes understanding the effects of steam, high heating rate, temperature on the kinetics of gibbsite conversion to smelter grade alumina.
