摘要
Abstract
The behavior of the reactant molecules on carbon materials surface, formation of adsorbed NO2 , dimer (NO)2, -NO2 or pyridine compounds from single component NO is reviewed. When NO and O2 coexists. NO is oxidized to NO2 by the adsorbed O2. When NO, O2 and NH3 coexists, the reaction occurs between adsorbed NH3 and adsorbed NO2. The mechanism of selective catalytic reduction (SCR) of NO on activated carbon fibers (ACF) catalyst is presented as follows. At a low temperature NH3-SCR follows the Langmuir-Hinshelwood mechanism. While at a high temperature NH3-SCR follows the Eley-Rideal mechanism. The catalyst pore structure characteristics and surface chemical functional groups are the main factors of the low temperature SCR of NO.关键词
