“…Mixed conducting oxides have been attracting much attention in view of their promising applications, such as cathode and anode materials for solid oxide fuel cells [1], membranes for pure oxygen production and conversion of hydrocarbons to value-added products [2][3][4][5][6][7][8][9]. Over the past two decades, a number of mixed conducting materials based on perovskite-type oxides have been developed to meet many kinds of requirements in practical applications.…”

“…During the last decade a large number of MIEC materials based on fluorite and perovskite structures have been synthesized and characterized [4]. However, due to this date, all of these materials basically share one common feature: the trade-off between oxygen flux and phase stability.…”

High temperature dense ceramic membranes made from mixed ionic/electronic conducting perovskite ceramics represent a high potential as a reliable source for oxygen and syngas production. In this work, La 0.2 Sr 0.8 Fe 0.8 Ta 0.2 O 3- based thin film perovskite system was evaluated, addressing the effect of structural surface modification on oxygen permeation rates. Membranes with 20 µm thick dense functional layer and varying surface area on permeate side were fabricated by a dip coating technique. Oxygen permeation was measured at temperatures between 800 and 1000 C by using varying partial pressure of O 2 as a driving force. Maximum O 2 flux values of 5.8 and 8.7 mlcm -2 min -1 were recorded for smooth and structured permeation surfaces, respectively. This indicates that the surface roughness, which corresponds to an increase in surface area at the permeate side; can lead to a significant improvement in oxygen permeation rates reaching 50 % at 1000 o C.

“…The utilization of membranes in gas or air separation processes is expected to increase to five times of its current value by 2020 [16]. Many studies are presently performed to enhance their chemical stability as well as gas separation performance at typical operational conditions [15]. Air Products Company has manufactured small-scale (O 2 production of 500 kg every day) ITM units that require only 40% of energy per kg of O 2 that are required by conventional large-scale cryogenic systems [16].…”

The present work aims at investigating oxy-fuel combustion of liquid fuels in a concentric parallel tube oxygen transport reactor (OTR) using BSCF ion transport membrane (ITM) for oxygen separation. A computational model was developed and validated utilizing the available experimental results. It is assumed that the same model will be sufficient to capture reasonable results with liquid fuel oxy-combustion. The use of ITMs to produce oxygen for the conversion of liquid fuels into thermal energy in an oxygen transport reactor (OTR) while capturing CO 2 is presented. In this case, the OTR has two functions: O 2 separation and reaction of evaporated liquid fuel with oxygen. A parametric study of the influence of parameters such as oxygen pressure in the feed and the permeate sides on the performance of the OTR is conducted. The effect of the rates of the feed flow and sweep flow on the permeation of oxygen permeation has been evaluated. Subsequently, the effects of flow rates of feed and sweep on temperature and reaction characteristics are also explored. The optimal flow rates and flammability limits for the present geometry model to obtain maximum output are suggested. The feasibility of using liquid fuels as potential fuel to be used in near future oxygen transport reactors is presented.
