Production of elemental sulfur from H{sub 2}S and CO{sub 2} derived from a coal desulfurization process. Quarterly technical process report, April 1, 1994--June 30, 1994

During the third quarter of this project, by using the apparatus previously setup for preparation of catalysts, the CoO-MoO{sub 3}-Al{sub 2}O{sub 3} catalyst was prepared and the thermal stability of the catalyst was tested. Efforts were made on the calibration and the programming of the two column GC of a Perkin Elmer Gas Chromatograph. Column A was used for detecting sulfur related substances such as H{sub 2}S, COS and CS{sub 2}, and column B was for CO, CH{sub 4} and H{sub 2}. All of the GC standard curves were obtained. Non-catalytic experiments were carried out by using the packed bed reactor system with blank, filled only with quartz wool and Al{sub 2}O{sub 3} support for future reference. A modified new reactor was designed to quickly quench the reaction and to prohibit the occurrence of re-equilibration of reaction products. Further thermodynamic analyses for the reaction of H{sub 2}S and CO, were performed using the Stanjan method.
