“…The apparent activation energy (EA) was graphically estimated at 50 kPa of transmembrane pressure from the plot of Figure 5(b), which gives 12.1 kJ/mol with the correlation coefficient R 2 ~ 0.97, hence comparable to other literature data [60][61][62][63][64][65][66][67][68], Table 3.…”

“…What reported above demonstrated that the presence of H2S in the model biogas feed stream affected negatively the catalyst and membrane performance in both the MRs. This was also recently confirmed by Yin et al [60], who carried out the SRB in a CR at 973 K, 120 kPa, and 3/1 as feed molar ratio, observing the CH4 conversion decrease from 85% (in the case of a model H2S free biogas stream supplying) to around 20% (using a model H2S containing biogas stream), Table 6. In addition, Papurello et al [64] observed lower catalytic performance during SRB in a CR exercised at 1073 K, 100 kPa and stoichiometric feed ratio owing to the negative effect of H2S present in the model biogas feed stream, registering the depletion of CH4 conversion from 99 to 22%.…”

“…One strategy to reduce the thickness and cost is to deposit a thin Pd or Pd-alloy film on the surface of porous substrate. This approach has been practiced extensively, where thin films of Pd or Pd-alloys were deposited on the porous substrate by various techniques such as electroless plating [13,14,15,16,17,18,19,20], sputtering [11,21,22,23,24,25,26], and chemical vapour deposition [27,28,29]. Non-metallic and metallic porous substrates such as ceramics [17,22,27,30,31], glass [21], and Porous Stainless Steel (PSS) [13,25,32,33,34,35] are widely employed.…”

Hydrogen Permeation through Porous Stainless Steel for Palladium based Composite Porous Membranes

Surface topography and hydrogen permeation properties of Porous Stainless Steel (PSS) substrates for thin-films deposition of Pd-based hydrogen separation membrane were investigated. Hydrogen permeance through the as-received PSS substrates demonstrated a wide range, despite a similar average surface pore size of 15 micron determined by SEM and confocal laser microscopy analyses. The surface pores of the PSS substrates were modified by impregnation of varying amounts of tungsten (W) powder. Maximum hydrogen flux reduction of only 28% suggested that W has a limited effect on the hydrogen permeation through the PSS substrate. Therefore, it is suggested that hydrogen transport through PSS substrates is mainly controlled by the substrate geometrical factors, particularly the ratio of the porosity to tortuosity (ε τ). The variation in the permeance between the nominally similar PSS substrates indicates the importance to independently assess the hydrogen transport characteristics of each of the components in a composite membrane.
