Dr Kwong is a senior lecturer in the School of Chemical Engineering at the University of Adelaide. He is the member of the Center for Energy Technology with specialization in greenhouse gas emission control and the combustion of fossil and biomass fuels, but also works with indoor air quality and sustainable waste management. His research focuses on developing low cost technologies to assist with the transition from fossil to sustainable economy. He is experienced in characterizing the emissions from the combustion of biomass and fossil fuels. His current research projects include the conversion of agricultural wastes into biochar for environmental mitigation using pyrolysis; combustion performance of producer gas for clean energy generation; and catalytic oxidation of methane for greenhouse gas emission control. He has published more than 40 articles in high-impact journals and peer reviewed conferences in the above fields. Apart from research, he also draws from his experience in environmental and energy engineering to develop a new course titled Biofuels, Biomass and Wastes for undergraduate and postgraduate sustainability education at the University of Adelaide.

Project 1: Engineering biochar production and renewable energy generation for agricultural sector
The proper waste management from agricultural operations can minimize the impact to climate change while increase the primary crop productivity. One mean to achieve this is to develop an integrated pyrolysis system utilizing the residues from agricultural sector for the co-production of renewable energy and solid carbon product (biochar or biomass derived black carbon). The biochar is returned to the same land that the feedstock originated, it not only stores carbon from the atmosphere to the soil, but also increases biomass productivity by improving the physical and chemical conditions of the soil. Despite the significant potential for biochar application in agricultural sector, there is still a lack of detail understanding on how the agricultural residuals can be used effectively to displace existing carbon-intensive energy sources and store carbon in soil. Besides, the environmental and health issues associated with the combustion of complex pyrolysis gases for renewable energy generation and biochar productions are poorly understood. To this end, we will establish the correlations among biochar characteristics, pyrolysis conditions and the associated atmospheric emissions from the conversion of various agricultural wastes. It is expected that the results from this study will provide a full set of optimum parameters for the clean conversion of agricultural residuals into biochar for renewable energy generation and carbon sequestration.
Project 2: Catalytic combustion system for ultra-lean methane from mine ventilation air
The development of low-cost technology to mitigate the methane content in coal mine ventilation air remains a challenge. All commercially viable technologies would benefit from the inclusion of a low range combustion system for ultra-lean methane (0.02-1vol%) mitigation, which could improve performance and lower operating costs by as much as 30%. To this end, we will develop a suite of novel ozone catalytic oxidation system and give superior performance for the combustion of ultra-lean methane in air mixtures at low temperature. We will use combinatorial chemistry to ensure optimum catalyst formulation for ozone oxidation reactions, and then evaluate the optimized materials in a porous burner system. This will enable the comparative improvement in performance, especially in ultra lean methane condition, resulting from the incorporation of the catalysts to be determined directly. The results of the study will be of relevance to the development of ultra-lean methane mitigation systems that extending concentration limits and lowering the reaction temperature of the state-of-the-art combustion system. The successful completion of the study will result in a reduction in the capital and operating costs of combustion-based mine ventilation air mitigation technologies.
Project 3: Chemical looping combustion of solid fuels
Chemical-looping combustion (CLC) is an innovative process with the potential to deliver efficient, clean and low-cost electricity using coal. CLC involves the use of a solid oxygen carrier (e.g. metal oxides), which has a high amount of lattice oxygen that provides the oxidant for the coal oxidation reactions rather than via the direct combustion of coal in either air or oxygen. The solid oxygen carrier is circulated between two reactors. In the fuel reactor, the fuel is oxidized by the oxygen carrier to produce a flue gas of H2O and CO2. The CO2 is recovered by condensing the water vapour and removing minor impurities, thus eliminating the need for independent pre- or post-combustion CO2 capture. The chemically-reduced oxygen carrier is then circulated to an air reactor, which converts it to an oxidized form for recirculation to the fuel reactor.
