| Outline of Final Research Achievements |
To understand the formation mechanism of organic chlorides by the reaction of HCl with carbonaceous particles, we used molecular orbital calculations for three carbon active site models (Armchair, Zigzag, and Tip types) to examine the effect of Zn doping on HCl adsorption. The molecular models of the carbon materials with or without Zn doping showed that the presence of Zn element increased the number of carbon active sites available for the chemical adsorption of HC. Furthermore, Zn doping changed the electronic state of the activesite of the carbon particle in the direction in which HCl was readily adsorbed. We also examined the HCl removal performance of cheap natural soda ash loaded on a honeycomb support as a hot gas cleanup method. The honeycomb-supported soda ash improved HCl removal extent at the 1-ppm breakthrough time compared to the result without the support. Under the present conditions, the removal extent was maximized at 500℃.
