Selective reduction of NO by photo-SCR with ammonia in an annular fixed-film photoreactor

YiangChen CHOU, Young KU

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 2,   Pages 149-155 doi: 10.1007/s11783-010-0296-9

Abstract: Gaseous NO was photocatalytically reduced at room temperature by photo-assisted selective catalytic reduction (photo-SCR) with ammonia over TiO in this study. NO reduction efficiency and N selectivity were determined from gases composition at the outlet stream of photoreactor. Effect of operating conditions, e.g. light intensity and inlet concentrations of ammonia and oxygen, on the NO reduction efficiency and N selectivity were discussed to determine the feasible operating condition for photocatalytic reduction of NO. Experimental results showed that selective catalytic reduction of NO with ammonia over TiO in the presence of oxygen was a spontaneous reaction in dark. The photoirradiation on the TiO surface caused remarkable photocatalytic reduction of NO to form N , NO , and N O under 254 nm UV illuminations, while almost 90% of N selectivity was achieved in this study. The ammonia and oxygen molecules played the roles of reductant and oxidant for NO reduction and active sites regeneration, respectively. The reduction of NO was found to be increased with the increase of inlet ammonia and oxygen concentrations until specific concentrations because of the limited active sites on the surface of TiO . The kinetic model proposed in this study can be used to reasonably describe the reaction mechanism of photo-SCR.

Strategic Research on Promoting Coordinated Development of Refining and Automobile Industries

Strategic Study of CAE 2019, Volume 21, Issue 3,   Pages 61-69 doi: 10.15302/J-SSCAE-2019.03.005

Abstract:

The rapid development of new energy vehicles such as electric vehicles and fuel cell vehicles has initiate the age of automobile power revolution. The internal combustion engine vehicle (ICEV) manufacturing industry and the petroleum production industry actively respond to the automobile power revolution by satisfying the latest requirement for emissions, upgrading the quality of oil products, and advancing the development of internal combustion engine technology. Although new energy vehicles have some advantages, they can not comprehensively replace the ICEVs in a short term. Gasoline electric hybrid vehicles with highefficiency internal combustion engines will significantly reduce pollutant and carbon emissions, which are in line with China’s national conditions. By 2050, ICEVs, gasoline electric hybrid vehicles, fuel cell vehicles, and pure electric vehicles will coexist based on their respective technological advantages. However, the ICEVs will still predominate in the automobile market by then, and the  ependence of automobile power on liquid fuels will exceed 60%. Therefore, the petroleum refining and automobile manufacturing industries should develop coordinately by studying the combustion mechanism from a molecular perspective in the internal combustion engines; exploring the relationship between fuel composition, distillation range, and particulate matter emissions, and developing simplified models; developing and promoting high-quality fuels and high-grade lubricants to adapt to the low-carbon and emission reduction requirements in the era of automotive power diversification.
