Two projects were announced in the late 1990 s to develop the ITM Process and another related technology. Air Products will lead an 8V2-year, US 90 million research project that is supposed to culminate in the construction of a 500 million SCFD Process Development Unit in 2005. Members of the team include McDermott, Ceramatec, Eltron Research, Battelle, Penn State University, ChevronTexaco, Norsk Hydro, University of Alaska - Fairbanks and the University of Pennsylvania.

The Pd-Au and Pd-Cu alloys retained their metallic luster upon exposure to hydrogen sulfide and recovered their activity after removal of H2S [74], implying that both alloys were resistant to formation of bulk sulfides. The unalloyed Pd and Pd-Ag membranes were much changed in appearance, according to McKinley, indicative of the formation of bulk sulfides. X-ray diffraction analysis at Eltron Research Inc. shows that unalloyed Pd forms the bulk sulfide, Pd4S, and that Pd-Ag alloys form bulk palladium-silver sulfides, leading to failure of membranes exposed to under 20 ppmv H2S in the range 593-713 K (320-440 °C) [75]. The Pd 60-Cu 40 (wt%) alloys resist formation of bulk sulfides, but were not completely satisfactory for use with H2S [75], in accord with the work of McKinley [74].

Figure 4.7 shows hydrogen flux data for membranes of Group IVB-VB material tested at Eltron Research Inc. using feeds containing various components of a water-gas shift mixture. The membranes were tested with a total pressure in the feed up to 450 psi (31.0 bar) and with argon sweep gas at ambient pressure. In an... 

Figure 4.8 shows the results of a long-term study at Eltron Research Inc. in a water-gas shift mixture containing 41.4 mol% H2, 3.3 mol% CO, 17.8 mol% CO2, and 37.3 mol% steam with a balance of inert gases. The study was conducted at ambient pressure for over 2800 h (4 months) under continuous operation in the water-gas shift mixture. Membrane catalysts were protected by guard bed adsorbents. After four months, a permeabUily of 1.0 x 10 mol m s" Pa" was maintained.

Finally, the editors would like to acknowledge the considerable effort of Vivian P. Knaus of Eltron Research Inc. for transforming the raw manuscripts into forms usable by the publisher. Without her expertise, the quality of the book would have been difficult to achieve.
