Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 4,   Pages 471-477 doi: 10.1007/s11705-014-1449-3

Abstract: Lithium -MnO ion-sieves were prepared from spinel LiMn O via treatment with nitric acid. The LiMn O was synthesized by a solid state reaction between LiOH·H O and MnO . The effects of the calcination time and temperature on the preparation of the LiMn O precursor and the lithium ion-sieve were investigated. In addition, the Li extraction ratio, the Mn dissolving ratio and the adsorption properties of the lithium ion-sieve were all measured. The lithium ion-sieve had a high exchange capacity and was selective for Li . Specifically, at pH= 13, the ion exchange capacity of Li was 30.9 mg/g in 10 mmol/L LiCl solution and the lithium extraction ratio and manganese dissolving ratio were 95% and 25%, respectively.

Chemical poison and regeneration of SCR catalysts for NO<sub><i>xi>sub>

Junhua LI,Yue PENG,Huazhen CHANG,Xiang LI,John C. CRITTENDEN,Jiming HAO

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 3,   Pages 413-427 doi: 10.1007/s11783-016-0832-3

Abstract: Selective catalytic reduction (SCR) of NO with NH is an effective technique to remove NO from stationary sources, such as coal-fired power plant and industrial boilers. Some of elements in the fly ash deactivate the catalyst due to strong chemisorptions on the active sites. The poisons may act by simply blocking active sites or alter the adsorption behaviors of reactants and products by an electronic interaction. This review is mainly focused on the chemical poisoning on V O -based catalysts, environmental-benign catalysts and low temperature catalysts. Several common poisons including alkali/alkaline earth metals, SO and heavy metals etc. are referred and their poisoning mechanisms on catalysts are discussed. The regeneration methods of poisoned catalysts and the development of poison-resistance catalysts are also compared and analyzed. Finally, future research directions in developing poisoning resistance catalysts and facile efficient regeneration methods for SCR catalysts are proposed.
