Description

  • Content 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.
