Biography
I am a research fellow in the Sustainable Process Technologies Group (Green Chemicals Beacon).
I had my undergraduate study in the field of Chemical Engineering at the University of Malaya (Malaysia). My research project during the Master program at National Taiwan University (Taiwan) was related to the micronization of active pharmaceutical ingredients with one of the supercritical fluid technologies termed as Rapid Expansion of Supercritical Solution. Before starting my PhD study, I worked as a biochemical research assistant at Academia Sinica, Taiwan for 2 years investigating the interaction mechanism of MinE protein with the cell membrane (government-funded project).
My Ph.D. study at the University of Nottingham was focused on the extraction of plant-based bio-flocculant from okra pods by using conventional hydrothermal and microwave heating methods followed by the characterisation of its bio-flocculating property for the application in wastewater treatment and sludge dewatering.
After the completion of Ph.D study, I worked as a senior engineer in the Environmental Sector of Nano & Advanced Materials Institute Limited (Hong Kong) for 1.5 years. I was responsible for a government and industry-funded project to develop and operate and optimise 3 systems: (1) nanobubble ozone oxidation system (10 and 50L) for treatment of textile wastewater focusing on removal of colour and COD, (2) nanobubble ozone oxidation system (80L) for sanitization of river water focusing on removal of E.coli and total bacteria, (3) continuous-mode pilot-scale (20 to 40mL/min sewage input) nanobubble-moving bed bio-reactor system for the treatment of sewage focusing on removal of COD, ammonia and total nitrogen.
For my current position, I focus on the development of a high efficient and environmentally friendly supercritical water gasification (SCWG) process by using biomass and its waste as the feedstock to generate green hydrogen. The factors that influence the gas yields will be investigated and the operating parameters will be optimised to maximise the hydrogen generation. The challenges that restrict the development of SCWG process (e.g. char formation, high energy requirement, reactor corrosion) will be tackled.
