Directing the Catalytic Hydrothermal Liquefaction of Lignocellulosic Biocrudes

This PhD project at the University of Sydney's School of Chemistry focuses on advancing the catalytic hydrothermal liquefaction (HTL) of lignocellulosic biocrudes. The research aims to improve control over the chemical composition of biocrude produced from waste cellulosic biomass, with the ultimate goal of enhancing the properties and valorisation potential of biocrude for industrial applications. The project is closely linked to industry partner Licella, targeting the development of renewable feedstocks and chemical monomers through process optimization and fractionation. Students will investigate how HTL processing parameters and catalyst inputs can be rationally directed to yield more desirable biocrude products. The work involves intimate knowledge of biocrude composition, feedback between concurrent PhD projects (catalytic and analytical), and collaboration to inform process choices and analytical strategies. Desired outcomes include a deeper understanding of fundamental reaction mechanisms, improved biocrude properties, and the ability to direct fractions for subsequent upgrading and industrial use. Key research areas include analytical chemistry, applied chemistry, environmental chemistry, and industrial chemistry. The project is well-suited for candidates with a strong background in chemistry or chemical engineering, and offers the opportunity to work at the interface of academic research and industrial innovation. Funding is not explicitly guaranteed, but the project is associated with CRC SPW and industry collaboration. Applications are accepted year-round, and interested candidates should apply via the provided Google Forms link and consult the MMY Group projects page for further information. Eligibility highlights include a relevant honours degree, laboratory research experience, and strong communication skills. International applicants may need to provide proof of English proficiency. This is an excellent opportunity for students interested in sustainable chemistry, catalysis, and renewable energy technologies.
