Abstract

Perovskite structures including oxygen vacancies are the most important group of the oxygen preamble MEMBRANEs. These MEMBRANEs have potentially attractive applications in the MEMBRANE reactors for partial oxidation of methane. Doping Perovskite phase in order to increase the oxygen vacancies and oxygen permeation, besides Perovskite structure STABILITY, has been the main approach of the recent researches. In this research, tantalum was chosen as the appropriate dopant for Ba (Co0.8Fe0.2) O3-d Perovskite phase, according to the tolerance factor calculations. The X ray patterns of synthesized Ba (Co0.7Fe0.2Ta0.1) O3-d indicate that the Perovskite structure was formed. Powder density, thermal expansion coefficient measurements and bond strength studies using FT-IR analysis revealed that the chosen dopant not only increases the oxygen vacancies volume but also reduces the thermal expansion coefficient without significant changes of bond strength. Results showed that the novel Ba (Co0.7Fe0.2Ta0.1) O3-d is a good choice for the MEMBRANE fabrication of methane partial reduction reactors.
