This project aims to generate new knowledge for the development of a novel hot gas cleaning technology. This project expects to understand the mechanisms of tar reforming using biochar as a renewable catalyst, which can avoid the problems associated with the catalyst deactivation and catalyst disposal if conventional supported catalysts are used. Expected outcomes of this project include a theoretical framework and a kinetic model describing the catalytic reforming of tar as part of the hot gas cleaning during the conversion of biomass. The technology will contribute to Australia’s improved energy security and reduced carbon dioxide (CO2) emissions in the carbon-constrained future.Read moreRead less

A green technology for liquefied natural gas (LNG) regasification. Upon arrival to its destination, the liquefied natural gas (LNG) exported from Australia must be converted back into gas to make it suitable for distribution to end users, for which the current technologies burn up to two per cent our LNG exports. This project will design a technology that will use the energy of ambient air, which will not only increase the profit but also reduce carbon dioxide emissions.
Near zero-emission hydrogen and carbon production from natural gas and bio-methane. Hydrogen is envisaged as a clean fuel for power generation particularly for the transportation sector. In the short- and mid-term future, hydrogen will be derived from fossil fuels. Based on the conventional processes, the route from fossil fuels to hydrogen invariably produces greenhouse gases. Geosequestration is a viable technique of storing carbon dioxide but has an uncertain long-term environmental ramifi ....Near zero-emission hydrogen and carbon production from natural gas and bio-methane. Hydrogen is envisaged as a clean fuel for power generation particularly for the transportation sector. In the short- and mid-term future, hydrogen will be derived from fossil fuels. Based on the conventional processes, the route from fossil fuels to hydrogen invariably produces greenhouse gases. Geosequestration is a viable technique of storing carbon dioxide but has an uncertain long-term environmental ramification. In contrast, our proposed technique avoids the production of greenhouse gases and, instead, engenders high value added graphitized carbon as a by-product. Given the relative stability and value of graphitized carbon, our catalytic cracking process provides another option to geosequestration.Read moreRead less
