Development of highly active coated monolith SCR catalyst with strong abrasion resistance for low-temperature application

Lina GAN,Shan LEI,Jian YU,Hongtao MA,Yo YAMAMOTO,Yoshizo SUZUKI,Guangwen XU,Zhanguo ZHANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6, Pages 979-987 doi: 10.1007/s11783-015-0824-8

Abstract: Monolith SCR catalysts coated with V O -WO /TiO were prepared by varying binder and coating thickness. Comparing with a monolith extruded with 100% V O -WO /TiO powder, a coated monolith with a catalyst-coating layer of 260 μm in thickness exhibited the similar initial NO reduction activity at 250°C. After 4 h abrasion (attrition) in an air stream containing 300 g·m fine sands (50–100 μm) at a superficial gas velocity of 10 m·s , the catalyst still has the activity as a 100% molded monolith does in a 24-h activity test and it retains about 92% of its initial activity at 250°C. Estimation of the equivalent durable hours at a fly ash concentration of 1.0 g·m in flue gas and a gas velocity of 5 m·s demonstrated that this coated monolith catalyst is capable of resisting abrasion for 13 months without losing more than 8% of its initial activity. The result suggests the great potential of the coated monolith for application to de-NO of flue gases with low fly ash concentrations from, such as glass and ceramics manufacturing processes.

Evaluation method of dam behavior during construction and reservoir filling and application to real dams

Yuji KOHGO, Akira TAKAHASHI, Tomokazu SUZUKI,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 1, Pages 92-101 doi: 10.1007/s11709-010-0009-2

Abstract: In this paper we analyzed a real fill-type dam, named the Minami-Aiki Dam, to verify a numerical consolidation method with an elastoplastic model for unsaturated soils. The validities were conducted by comparing the analyzed and measured values during construction and impounding. The settlements calculated showed good agreement to those observed. Though the changing patterns of the measured and calculated pore water pressures were similar, the amounts of pore water pressures induced by the self-weights of embankment and the dissipation speeds were different. The earth pressures measured at the bottom of the core zone showed good agreement with those calculated. This method is valid for estimating behavior of fill-type dams during construction and impounding.

Determination of aniline derivatives in water samples after preconcentration with oxidized multiwalled carbon nanotubes as solid-phase extraction disk

Hideyuki KATSUMATA, Yuta ODA, Satoshi KANECO, Tohru SUZUKI, Kiyohisa OHTA

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 3, Pages 270-275 doi: 10.1007/s11705-012-1298-x

Abstract: A sensitive and selective preconcentration method using solid-phase extraction (SPE) disk made from oxidized multiwalled carbon nanotubes (OMWCNTs), has been developed for the determination of aniline derivatives, such as 2-nitroaniline (2-NA), 4-nitroaniline (4-NA), and 2,4-dichloroaniline (2,4-DCA) in water samples. Anilines were extracted onto OMWCNT disk and then determined by high performance liquid chromatography (HPLC) with UV detector. Several parameters on the recovery of the analytes were investigated. The experimental results showed that it was possible to obtain quantitative analysis when the solution pH was 8 using 200 mL of validation solution containing 2 μg of anilines and 10 mL of acetonitrile/ethanol (8/2, v/v) as an eluent. Relative standard deviations for five determinations were 7.5% (2-NA), 6.5% (4-NA) and 3.8% (2,4-DCA) under optimum conditions. The linear range of calibration curves were 0.5 ng·mL to 15 ng·mL for each analyte with good correlation coefficients. The detection limits (3S/N) of 2-NA, 4-NA and 2,4-DCA were 30 pg·mL , 31 pg·mL and 26 pg·mL , respectively. Our method was successfully applied to the determination of aniline compounds in river water sample with high precision and accuracy.

An overview and recent advances in electrocatalysts for direct seawater splitting

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 6, Pages 1408-1426 doi: 10.1007/s11705-021-2102-6

Abstract: In comparison to pure water, seawater is widely accepted as an unlimited resource. The direct seawater splitting is economical and eco-friendly, but the key challenges in seawater, especially the chlorine-related competing reactions at the anode, seriously hamper its practical application. The development of earth-abundant electrocatalysts toward direct seawater splitting has emerged as a promising strategy. Highly efficient electrocatalysts with improved selectivity and stability are of significance in preventing the interference of side reactions and resisting various impurities. This review first discusses the macroscopic understanding of direct seawater electrolysis and then focuses on the strategies for rational design of electrocatalysts toward direct seawater splitting. The perspectives of improved electrocatalysts to solve emerging challenges and further development of direct seawater splitting are also provided.
