The application of the membrane reactor to steam reforming of methanol was studied as a hydrogen producing reaction. The activities, stabilities and selectivities of Cu/ZnO, Ni/Al2O3 and Ru/Al2O3 catalysts were tested using a conventional fixed-bed flow reactor. Ni/Al2O3 catalyst showed the most stable activity at 723 K but relatively low hydrogen yield because of methanation. However, the hydrogen-permeable membrane reactor suppressed methanation and hydrogen yield was enhanced compared with the conventional reactor. The membrane reactor was more effective at higher temperatures and higher W/F.

“…At present, Pd or Pd-Ag alloys are utilized to produce high purity hydrogen, but Pd is a very expensive and scarce element. 1,2) Therefore, it is urgent to develop new, low cost and high performance non-Pd-based hydrogen permeation alloys. During the past decade, V-based hydrogen permeation alloys have been actively investigated by Nishimura et al 3,4) Yamaura et al have investigated the melt-spun amorphous Ni-Nb-Zr alloys as new membranes.…”

Maximum cold rolling reduction rates of as-cast Nb 40 Ti 30Àx Zr x Ni 30 alloys were measured to evaluate ductility by measuring the change in the thickness. 50% or higher reduction rates were obtained for the alloys containing the Zr content of 12 mol% or less, but lower values were obtained for the alloys substituted with more Zr. Changes of hydrogen permeability (È) and microstructures of the Nb 40 Ti 18 Zr 12 Ni 30 alloy caused by cold-rolling and subsequent vacuum annealing were investigated. È of this alloy was reduced to the half of the as-cast one by the 50% reduction rate, but recovered to 3:23 Â 10 À8 [molH 2 m À1 s À1 Pa À0:5 ], which is 1.13 times higher than that of as-cast one, by a subsequent annealing for 360 ks at 1273 K. Although the eutectic phase disappeared and was replaced by a small spherical (Nb, Ti, Zr) phase embedded in the (Ti, Zr)Ni matrix after rolling and subsequent annealing, these alloys showed good resistance to the hydrogen embrittlement at 523 K or more.

“…The pioneering work on electroless plating technique to prepare a Pd composite membrane was performed in the group of Kikuchi, et al [3][4][5][6]. The composite membrane exhibited an H 2 permeation rate at least 10 times larger than that of a commercial Pd-based membrane with a thickness of 150 m and had a high permselectivity of H 2 .…”
