Reduction of NOx by H2 over Pt-K/Al2O3 Lean NOx Trap catalysts
Introduction Lean NOx Trap (LNT) catalysts are viable catalysts for the abatement of NOx emissions from lean–burn engines [1]. These systems work under periodic cyclic conditions, alternating lean (NOx storage) and rich conditions during which the stored NOx are reduced by a reductant. Although PtBa/Al2O3 is a typical model catalyst for this application, systems containing K have also been prop...
متن کاملLean NOx reduction over Ag/Al2O3 catalysts using future fuels
The focus of this work is to increase the understanding of the lean NOx reduction over silver-alumina catalysts using hydrocarbons as the reductant (HC-SCR). In particular, the effect of silver loading, the role of platinum doping, the effect of the reducing agent as well as the effects of aging and hydrothermal treatment on the catalytic activity, in particular at low temperatures, and selecti...
متن کاملExperimental investigation of the reduction of NOx species by CO over Pt-Ba/Al2O3 Lean NOx Trap systems
Introduction Lean NOx Traps (LNTs) represent a viable solution for the abatement of NOx emissions from lean–burn engines [1]. Several studies were published on the mechanisms of both the NOx storage [1] and reduction [2], but a complete understanding of these processes has not yet been achieved. We have previously shown that on Pt-Ba/Al2O3 LNT systems the reduction of nitrates by H2 involves a ...
متن کاملBioacid hydroconversion over Co, Ni, Cu Mono- and indium-doped bimetallic catalysts.
Caprylic acid (CA) as model reactant was selectively reduced in a flow-through reactor in hydrogen stream at 21 bar total pressure and 240-360 °C over alumina loaded with the adjacent Co, Ni, Cu host and In guest metals. The main target of this research is the recognition of efficient cobalt catalysts for carboxylic group hydroconversion compared to more familiar nickel and copper composites. T...
متن کاملThe Selective Catalytic Reduction of NOx with NH3 over Titania Supported Rhenium Oxide Catalysts
Titania supported vanadium oxide catalysts have been demonstrated to be very efficient catalysts for the selective reduction of NOx with NH3 and have found widespread industrial application for the control of NOx emissions from stationary sources (1). Characterization studies have demonstrated that supported vanadium oxide catalysts consist of a two-dimensional metal oxide overlayer on the oxid...
