The TIN 5 wt %Ni membrane was researched for gasification of coal technique separating hydrogen from fossil fuel In general, Pd and Pd based alloy membranes of separating hydrogen were reported to have the good property of hydrogen selectivity at high temperature but they has some problems such as hydrogen embrittlement and high material costs Therefore materials with good properties of hydrogen selectivity are needed instead of Pd In this research we fabricated membranes for hydrogen permeation that are highly resistant to acids chemically steady and composed of the economical substance, TIN Our laboratory investigated hydrogen selectivity TIN powder was milled for 30 60 and 240 mm by a vibration mill respectively Afterwards the samples underwent operate spark plasma sintering and was characterized by XRD BET and SEM Also hydrogen selectivity was measured by Sievert s type hydrogen permeation membrane equipment In this report the hydrogen permeability of the TiN 5 wt %Ni membrane was measured to be 7 8 x 10(-8) 1 7 x 10(-7), and 1 4 x 10(-7) mourn s Pa(1/2) at 473 573 and 673K under 0 2 MPa H(2) atmosphere, respectively Crown Copyright (C) 2010 Published by Elsevier Ltd on behalf of Professor T Nejat Veziroglu All rights reserved
