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 کاملEconomics of Pollution Trading for SO2 and NOx
For years economists have urged policymakers to use market-based approaches such as cap-and-trade programs or emission taxes to control pollution. The SO2 allowance market created by Title IV of the 1990 U.S. Clean Air Act Amendments represents the first real test of the wisdom of economists’ advice. Subsequent urban and regional applications of NOx emission allowance trading took shape in the ...
متن کاملProjections of SO2, NOx and carbonaceous aerosols emissions in Asia
Estimates of Asian emissions of air pollutants and carbonaceous aerosols and their mid-term projections have been changing significantly in the last years. The remote sensing community has shown that increase in NOx in Central East Asia is much stronger than any of the emission inventories or projections indicated so far. A number of studies reviewing older estimates appeared. Here, we review t...
متن کاملModeling and Simulation of NOx Abatement with Storage/Reduction Catalysts for Lean Burn and Diesel Engines
The removal of nitrogen oxides emitted by diesel and lean burn engines is one of the most important targets in catalytic exhaust aftertreatment research. Besides the selective catalytic reduction (SCR) reaction with ammonia the most promising approach is the NOx Storage and Reduction Catalyst (NSR) which utilizes the nitrogen oxides storage on barium sites to form nitrates during the lean phase...
متن کاملLow NOx Combustion Technology for Minimizing NOx
A noble low NOx combustion technology, based on partial oxidation combustion concept in a fuel rich combustion zone, is successfully applied in this research. The burner is designed such that a portion of fuel is heated and pre-vaporized in the furnace then injected into a fuel rich combustion zone so that a partial oxidation reaction occurs. The effects of equivalence ratio, thermal load, and ...
