The science and engineering of metal derivative based technologies are characterized by the interplay among a broad spectrum of subjects in connection to metal derivative physics, chemistry and reaction engineering, and particle science and technology. These subjects encompass three main components - Materials: metal derivative material synthesis, reactivity, reaction-regeneration mechanism, recyclability, and physical strength; Reactors: flow pattern and stability, gas-solid contact mechanics, scaling rule; and Systems: process integration, intensification, and optimization. Such interplay is so complex that it has been over 100 years in which this technology has not been able to be commercially deployed. However, with major advances made recently on the bottleneck areas in this technology development, the technology commercialization is now realistically possible and can be projected to take place in the near future. Using metal oxides as an example, these advances include the successful development of chemically, physically robust metal oxide oxygen carriers that are cost-effective and sustainable to long-term redox reactor environment, and the successful employment of CO2 and H2O as partial substitute of carbonaceous feedstock for combustion, gasification and reforming applications thereby yielding CO2 negative chemical looping processes. These advances coupled with a novel reactor system design and operation give rise to a significant reduction in the capex compared to conventional approaches, when the chemical looping technology is used for carbonaceous feedstock conversions in the production of electricity, hydrogen, syngas, liquid fuels, and chemicals. The general concept of chemical looping can also have varied technology applications. For example, the SULGEN Process recently invented at Ohio State can be in one step capturing H2S and another step separating it to hydrogen and sulfur. It can potentially be applied to petroleum fuel refining process, natural gas sweetening process, and other fossil fuel gasification and reforming processes. This presentation will describe these advances that are established over the OSU chemical looping system platform. The presentation will also illustrate the rationales of its commercialization readiness and timeline.
