Synopsis:
CO2 capture technologies are sought to help avoid bulk anthropogenic emissions, to help decarbonize the world economy. The conversion of CO2 wastes into energy rich hydrocarbons via reductive hydrogenation with solar-H2 is attractive for the transformation of renewable solar-H2 into more readily managed hydrocarbon fuel, and reliable net zero emission hydrocarbon-based power generation if coupled with CO2 capture.
CO2 capture via solid supported amine type adsorbents is of interest to provide a more energy efficient option than incumbent absorption processes, by virtue they provide large selective CO2 capacities, are water tolerant, and are not complicated by volatility or corrosion issues. MOF derived products (MDPs) are targeted to provide superior transition and noble metal based heterogeneous catalysts for CO2 conversions, based on the high surface area and high metal dispersion of the MOF precursors.
Accordingly, this presentation will discuss the development of such solid amine type sorbents and their study for CO2 post combustion capture (PCC) and CO2 capture from air applications, and the discovery of new sorbent/process designs that mitigate their deactivation via urea formation. It will also report on the development of new materials derived via the controlled decomposition of MIL-100(Fe), both with and without prior infiltration with polymeric precursor, and the assessment of the utility of these MDPs to catalyze CO2 hydrogenation to hydrocarbons.
Biography:
Dr Gregory Knowles is a Senior Research Manager with interests in nano / nanoporous materials, physico-chemical characterizations, mechanistic studies, carbon capture and conversion, and catalysis. His activities encompass research program design, proposal preparation, capacity building, marketing, supervision, laboratories management, and training; and materials synthesis, process and experiment design, and practice.
Alan Chaffee, Professor, School of Chemistry, Monash University, Australia.
Alan Chaffee’s career has spanned the 3 major research sectors in Australia: CSIRO, private industry (BHP) and University (Monash). Though he started out as an organic chemist, movement between these sectors has led to cross-disciplinary research interests. His group’s activities focus on both fundamental and applied issues in the utilisation of natural carbonaceous resources. This includes the development of high value products from coal and biomass as well as the capture and utilisation of associated CO2 emissions.
