School of Chemical Engineering


Luisa Prasetyo received her Bachelor of Chemical Engineering (First Class Honours) from The University of Queensland in 2014. She started her PhD in 2015 and her research focuses on the fundamental study of adsorption processes in carbonaceous solids. The microscopic mechanism of adsorption is investigated with the combined study of high-resolution volumetric adsorption experiments and Grand Canonical Monte Carlo (GCMC) simulations. 

Research Project

Title: Fundamental study of adsorption of non-polar and polar fluids on hydrophilic and hydrophobic ordered solids

Advisors: Prof. Duong D. Do, Prof. David Nicholson

Brief Summary of project:

Adsorption of gases on carbon surface has been a subject of interest by many due to its increasing use as an economical process for separation and purification in chemical and biochemical industries. To optimise these processes, a good fundamental understanding of the microscopic mechanisms of adsorption and desorption is required. Even though there are numerous experimental and simulation studies on adsorption of various gases on carbon, there are a number of unresolved issues that remain to date, for example (1) unusual hysteresis at temperatures below the triple point, (2) formation of commensurate and incommensurate packing of noble gases adsorption on graphite, and (3) formation of bilayer of polar molecules, especially those that can form a hydrogen bonding, such as tertiary butanol. The aim of this thesis is to address these issues with the combined study of high-resolution experiments and Monte Carlo simulations.
