Selection of kinetics model of Fe2O3/CeO2 and Fe2O3/CeO2ZrO2 on reduction reactions for three reactor chemical looping system |
| 초록 |
Three reactor chemical looping (TRCL) system is one of the promising technologies for pure hydrogen production without emission of carbon dioxide from methane. The objective of this study was to obtain the kinetics model of reduction reactions taking place in the TRCL system using oxygen carriers as like Fe2O3/CeO2 and Fe2O3/CeO2ZrO2. The experiment tests are carried out in a thermogravimetric analysis (TGA), using methane as a reducing gas. The selection of kinetics models is preformed via a selecting method of kinetics models presented by Hancock and Sharp. The values of activation energy are determined from the selected kinetics models, which are compared with the value of activation energy of Fe2O3/ZrO2. Morphological properties and structures of the oxygen carriers are observed by SEM and XRD. |
