Journal ArticleDOI

U. Balachandran,J. T. Dusek,R.L. Mieville,Roger B. Poeppel,M.S. Kleefisch,S. Pei,T.P. Kobylinski,C.A. Udovich,Arun C. Bose +8 more
TL;DR: In this paper, perovskite type oxides (ABO3) containing transition metals on the B-site show mixed (electronic/ionic) conductivity, and extruded tubes of these materials have been evaluated in a reactor operating at ca. 850°C for direct conversion of methane into syngas (CO + H2) in the presence of a reforming catalyst.
Journal ArticleDOI
Failure mechanisms of ceramic membrane reactors in partial oxidation of methane to synthesis gas
S. Pei,M.S. Kleefisch,T.P. Kobylinski,J. Faber,C.A. Udovich,V. Zhang-McCoy,B. Dabrowski,U. Balachandran,R.L. Mieville,R. B. Poeppel +9 more
TL;DR: In this paper, the authors examined the starting material and fractured membranes using a combination of X-ray diffraction and thermogravimetric analyses and found that the first type of fracture was the consequence of an oxygen gradient in the membrane, pointing from the reaction side to the air side, leading to fracture.
Journal ArticleDOI
Ceramic membrane reactor for converting methane to syngas
TL;DR: In this article, the chemical phase behavior of the ceramic powders with varying stoichiometries was studied by high-temperature in-situ X-ray diffraction (XRD) as a function of oxygen partial pressure.
Journal ArticleDOI
Transport properties of BaCe0.95Y0.05O3−α mixed conductors for hydrogen separation
TL;DR: In this paper, the transport properties of a mixed ionic-electronic conductor, BaCe0.95Y0.05O3−α (BCY), were characterized by using impedance spectroscopy and open-cell voltage measurements.
Journal ArticleDOI
Hydrogen permeability of SrCe1−xMxO3−δ (x=0.05, M=Eu, Sm)
TL;DR: In this article, the hydrogen permeability of SrCe0.95Eu0.05O3−δ and Sce 0.95Sm0.5O3+δ was studied as a function of temperature, hydrogen partial pressure gradient, and water vapor partial pressure (PH2O) gradient.
