COS gas trapping ability at low temperature using strong bridge bonding of fixed potassium on activated carbon |
| 초록 |
The power generation process used for gasification of coal to drive the fuel cell has a better emission reduction effect of the greenhouse gas as compared with the existing power generation, and shows excellent efficiency. However, in the process of gasification, a sulfur compound is generated, and this by-product causes poisoning of the fuel cell and deteriorates its performance. The aim of this research is to develop an adsorbent for the removal of toxic COS gas among the sulfur compounds released during the process of coal power generation. We have tried to make adsorbent which is in the form of a crosslinked carbonate form by adding KOH to activated carbon which is inexpensive and porous and shows good adsorption power. The content of activated carbon was fixed at 80% to optimize adsorption at low temperature. The synthesized adsorbents were characterized by XRD, SEM and BET. In addition, the adsorption/desorption mechanism was analyzed by FT-IR, XPS and MASS analysis. |
