Production of elemental sulfur and methane from H{sub 2}S and CO{sub 2} derived from a coal desulfurization process. Quaterly technical progress report, October 1, 1996--December 31, 1996

PDF Version Also Available for Download.

Description

During the thirteenth quarter of the project, the catalytic reaction of H{sub 2}S and CO{sub 2} was carried out around the temperature of 450 to 550{degrees}C to explore the possibility of sulfur removal by solid adsorbents. The experiments combined two unit operations of catalysis and adsorption. A thermogravimetric analyzer (TGA) and a total sulfur analyzer (TSA) were used to investigate the effectiveness of the selected adsorbents used in the H{sub 2}S decomposition process. Three adsorbents, activated carbon, iron sulfide and sulfided Co-Mo-alumina catalyst in the form of powder, were selected for the experiments. The results showed that activated carbon and ... continued below

Three adsorbents, activated carbon, iron sulfide and sulfided Co-Mo-alumina catalyst in the form of powder, were selected for the experiments. The results showed that activated carbon and Co-Mo-Alumina catalyst powder could adsorb up to 9 percent of sulfur in weight. However, the experimental results indicated that there were only trace amount of elemental sulfur produced during the desorption test for the adsorbents.
