During the tenth quarter of the project, bench scale experiments were performed to investigate the adsorption ability of different kinds of materials within sulfur vapor environment. Four kinds of adsorbents have been tested. The experimental results indicated that activated carbon was the best of four adsorbents tested. In addition to the baseline tests, several designs of activated carbon feed system have been tested. Under an inert environment, bench scale experiments were performed to investigate the characteristics and efficiency of activated carbon passing through the Co-Mo-Alumina catalyst bed. The results showed that activated carbon powder could easily be transported through the catalytic bed. The adsorption process may be applicable to promote conversion of H{sub 2}S in the H{sub 2}S and CO{sub 2} reaction system
