description: The program objective is to identify and evaluate a technique to
 remove hydrogen sulfide from geothermal steam before it is used for power
 generation. The last six months were spent in the literature search, sorbent
 preparation and evaluation, and construction of an experimental apparatus.
 Zn0, mentioned in the original proposal as a good candidate for H/sub 2/S
 adsorption, was verified as such by the literature search and laboratory
 experiments. However, regeneration of sulfided sorbent proved to be difficult.
 The interests were, then, switched to formulating sorbents made of mixtures of
 different kinds of metal oxides. At present, two sorbents were formulated
 which, when evaluated with a gas adsorption apparatus in the laboratory,
 possess better H/sub 2/S adsorption-regeneration capabilities than Zn0 or
 sorbents obtained from catalyst manufacturers. Large-scale gas adsorption
 equipment for use with simulated geothermal steam has been designed, built and
 shakedown operation of the equipment is in progress.
