DEVELOPMENT OF A NOVEL CHEMICAL-LOOPING COMBUSTION - SYNTHESIS OF A LOOPING MATERIAL WITH A DOUBLE METAL-OXIDE OF COO-NIO

A new material as a solid looping reactant for a novel chemical-loopin g combustion may lead to a new technology for mitigation of greenhouse gas and efficient use of energy. In this study, we have identified th e fundamental features of several looping materials, which experience both reduction (fuel with metal oxide) and oxidation (the reduced meta l with air), by using a thermogravimetric reactor (TGR). Furthermore, by synergetic combination of nickel oxide with cobalt oxide, we have s ynthesized a new looping material by use of a double metal oxide and b y addition of YSZ. We found that this new looping material of CoO-NiO/ YSZ has an excellent performance in high reactivity, complete avoidanc e of carbon deposition, and good repeatability. This finding supports the fact that this new solid reactant obtained here is a suitable loop ing material for application of the chemical-looping combustion.
