During the eleventh quarter of the project, new flowmeters were replaced in the reaction system and calibrated to control the flowrate of HS, CO2, H2, and N2. The experimental results from quartz tube reactor were summarized in tabular form. The results showed that H2S conversion increased with increasing temperature from 500 to 600 deg C when used with the CoO-MoO3-Alumina catalyst. Bench scale experiments were set and performed to further investigate the adsorption ability of activated carbon which was the best of four adsorbents tested last quarter. At the same time, several designs of activated carbon feed system were tested. Under both an inert and a real reaction environment, bench scale experiments were performed to investigate the characteristics and efficiency of activated carbon passing through the CoO-MoO3-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 H2S in the H2S and CO2 reaction system.
