Biographical details

Dr. Montoya completed his Ph.D in Chemical Sciences in 2002 at the Universidad de Antioquia -Colombia. He received the prestigious Sesqui Postdoctoral Fellowship from the University of Sydney (2004 -2007). He joined the School of Chemical and Biomolecular Engineering at the University of Sydney as a lecturer in 2007 and was promoted to Senior Lecturer in 2010. Dr. Montoya has been a visiting scholar at Tsinghua University (INNET), and the University of Utah (Department of Chemistry and the Department of Chemistry and Fuel Engineering).

Research interests

Dr Alejandro Montoya’s research into reactive materials aims to bridge the gap between material properties at atomic scale and their useful large-scale applications in processes related to energy and chemical industrial sustainability. His unique research program in chemical engineering combines experimental (in small- and large-scale reactors) with simulation-based techniques.

“My research concentrates on biomass liquefaction, CO2 carbonation, surface processes and catalysis, combustion and atmospheric environments.

“I concentrate on developing predictive methods that can be used to optimise already established industrial processes and formulate new conditions for innovative applications.

“For example, my research into the hydrothermal liquefaction of biomass looks at developing reactive models to optimise the transformation of low-value materials into high-value products. My recent efforts have concentrated on the use of algae, breaking down its components (such as proteins, lipids and carbohydrates) to produce products that can be used as biofuels for powering engines, and at the same time potentially producing valuable pharmaceuticals.

“My work on CO2 carbonation is concerned with the heat pre-treatment of serpentine minerals to accelerate the leaching of cations for precipitation with CO2 to form carbonates, which are environmentally friendly solids that are able to retain CO2 permanently. I am working on predictive techniques to reduce the intensity of heat required to treat the rock, activate it, extract ions from it and induce the reactivity of these ions with the carbon dioxide.

“These predictive models based on first principles will then be able to be extended to any material to determine structural, electronic and reactivity properties.

“I’m passionate about my research because it’s an area that’s starting to make a real difference to the way chemical processes are optimised in industry.

“The University of Sydney has offered me excellent opportunities to develop my career, initially through a Sesqui Postdoctoral Fellowship, and now as an academic in the School of Chemical Engineering.”
