ABSTRACT:
A process for disassociating H.sub.2 S in a gaseous feed using an improved catalytic material in which the feed is contacted at a temperature of at least about 275.degree. C. with a catalyst of rutile nanocrystalline titania having grain sizes in the range of from about 1 to about 100 nanometers. Other transition metal catalysts are disclosed, each of nanocrystalline material with grain sizes in the 1-100 nm range.
