지르코니아를 고정한 실리카($ZrO_2-SiO_2$)와 망가니즈 산화물($MnO_x$)에 백금을 담지하여 제조한 촉매에서 수소에 의한 일산화질소의 선택적 촉매 환원($H_2$-SCR) 반응을 조사하였다. $Pt-MnO_x$ 촉매에서는 NO 전환율이 낮으며, $N_2O$와 $NO_2$ 생성이 억제되었다. 반면, $Pt/ZrO_2-SiO_2$ 촉매에서는 NO 전환율이 높지만, $100{sim}150^{circ}C$에서는 $N_2O$가, $200{sim}300^{circ}C$에서는 온도가 높아지면 $NO_2$ 수율이 높아져, $N_2$ 수율이 낮았다. $ZrO_2-SiO_2$에 $MnO_x$와 백금을 같이 담지한... -

People have been concerned about mercury emissions for decades because of the extreme toxicity, persistence, and bioaccumulation of methyl Hg transformed from emitted Hg. This paper presents an overview of research related to mercury control technology and identifies areas requiring additional research and development. It critically reviews measured mercury emissions progress in the development of promising control technologies. This review provides useful information to scientists and engineers... -

mercury in fue gas over MnOx/alu- mina. MnOx/Al2O3 showed a signifcant adsorption capability to capture Hg 0 in the absence of hydrogen chloride (HCl). The ideal adsorption temperature was about 600 K (Fig. 4). Mercury removal with catalytic oxidation, particularly when used in conjunction with sulfur (S), chloride (Cl), or iodine (I) impregnation, has also been studied for the removal of Hg 0... -
