    摘要: A detection system is presented. The detection system includes a sensing component and a data analyzer. The sensing component includes a first sensor and a second sensor in fluid communication with the first sensor. The first sensor is disposed to allow operation at a predetermined temperature T1 and is selective to a first gas species at T1 and in presence of a second gas species. The second sensor is disposed to allow operation at a temperature T2 and is sensitive to the first gas species and a second gas species at T2. Temperature T2 is lower than T1. The data analyzer is disposed to receive an output signal from the sensing component and configured to calculate concentrations of the first gas species and the second gas species based on the output signal from the sensing component. A method of calculating concentrations of gas species in a gaseous mixture is also presented.

    摘要: Methods for separating carbon dioxide from a fluid stream at a temperature higher than about 200° C. with selectivity higher than Knudsen diffusion selectivity include contacting a porous membrane with the fluid stream to preferentially transport carbon dioxide. The porous membrane includes a porous support and a continuous porous separation layer disposed on a surface of the porous support and extending between the fluid stream and the porous support layer. The porous support comprises alumina, silica, zirconia, stabilized zirconia, stainless steel, titanium, nickel-based alloys, aluminum-based alloys, zirconium-based alloys or a combination thereof. Median pore size of the porous separation layer is less than about 10 nm, and the porous separation layer comprises titania, MgO, CaO, SrO, BaO, La2O3, CeO2, HfO2, Y2O3, VOz, NbOz, TaOz, ATiO3, AZrO3, AAl2O4, A1FeO3, A1MnO3, A1CoO3, A1NiO3, A2HfO3, A3 CeO3, Li2ZrO3, Li2SiO3, Li2TiO3, Li2HfO3, A4N1yOz, YxN1yOz, LaxN1yOz, HfN2yOz, or a combination thereof; wherein A is La, Mg, Ca, Sr or Ba; A1 is La, Ca, Sr or Ba; A2 is Ca, Sr or Ba; A3 is Sr or Ba; A4 is Mg, Ca, Sr, Ba, Ti or Zr; N1 is V, Nb, Ta, Cr, Mo, W, Mn, Si or Ge; N2 is V, Mo, W or Si; x is 1 or 2; y ranges from 1 to 3; and z ranges from 2 to 7.

The second layer has a plurality of unconnected pores. At least a portion of the plurality of unconnected pores of the second layer is at least partially filled with a filler such that the first layer is substantially free of the filler. At least a portion of the plurality of unconnected pores of the second layer is in fluid communication with at least one of the pores of the first layer. A method of making a membrane structure is provided. The method includes the steps of providing a first layer having a plurality of interconnected pores; disposing a second layer on the first layer, and filling at least a portion of the unconnected pores of the second layer with a filler such that the first layer is substantially free of the filler. Disposing a second layer includes depositing a metal layer on the first layer; and anodizing the metal layer to convert the metal layer into porous oxide layer.
