Device for separating fluid comprising a mixed conducting membrane based multi-metal oxide component.

摘要

The present invention concerns a separation device FLUIDS, OXYGEN CAPABLE OF REMOVING, FROM A GAS MIXTURE CONTAINING OXYGEN. Said device employs at least one solid-state membrane comprising a metal oxide layer MULTICOMPONENT CONDUCTIVE, MIXTA, FORMED FROM A METAL OXIDE MULTICOMPONENT CONDUCTOR JOINT represented by the LN formula X '' X '' A '' ' 'X' 'B SUB, and B' 'Y' 'O 3-Z', wherein Ln is an element selected from the F BLOCK lanthanides, A 'is selected from Group 2 OF PERIODIC, A '' is selected from Groups 1, 2 AND 3 AND F BLOCK lanthanides, YB, and B '' are independently selected FROM D BLOCK transition metals, EXCLUDING TITANIUM AND CHROMIUM, where 0 = X 1, 0 X '= 1, 0 = X' '1, 0 Y 1, 0 = Y' 1, X + X '+ X' '= 1.0, 1.1 y + y' ' 1.0 and z is a number that makes the compound charge neutral. MIXED METAL OXIDES MULTICOMPONENT of the invention demonstrate increased resistance to degradation by CARBON DIOXIDE AND SULFUR DIOXIDE, FLOW IMPROVED OXYGEN AND REDUCED SPEEDS PLASTICA creep, temperature of use.
