Urban hydrological responses to climate change and urbanization in cold climates.

This study explores hydrological response of urban catchment in Southern Finland to climate change and urbanization. Process-based urban hydrological modelling and statistical analysis are applied to various urbanization and climate scenarios. Future changes in precipitation and temperature under Representative Concentration Pathways 4.

Poisoning-Resistant NO Reduction in the Presence of Alkaline and Heavy Metals over H-SAPO-34-Supported Ce-Promoted Cu-Based Catalysts.

Selective catalytic reduction (SCR) of NO using NH in the presence of alkaline and heavy metals is still an issue in the application of a stationary source. Reported here is the rational design of a novel H-SAPO-34-supported ceria-promoted copper-based catalyst (CuCe/H-SAPO-34) that demonstrates exceptional resistance against alkali (K), alkaline earth (Ca), and heavy metal (Pb) poisoning during SCR of NO. The H-SAPO-34 support contained numerous acid sites that allowed Cu-based catalysts to maintain their catalytic activity while also resisting poisoning by K and Ca.

Dual Promotional Effects of TiO-Decorated Acid-Treated MnO Octahedral Molecular Sieve Catalysts for Alkali-Resistant Reduction of NO .

Alkali metals generated during waste incineration in power stations are not conducive to the control of nitrogen oxide (NO ) emission. Hence, improved selective catalytic reduction of NO with ammonia (NH-SCR) in the presence of alkali metals is a major issue for practical NO removal. In this work, we developed a novel TiO-decorated acid-treated MnO octahedral molecular sieve (OMS-5(H)@TiO) catalyst with improved alkali-resistant NO reduction at low temperature, and the dual promotional effects of OMS-5(H)@TiO catalysts were clarified.
