NOx selective catalytic reduction at high temperatures with mixed oxides derived from layered double hydroxides

2012

[EN] Mixed oxides derived from layered double hydroxides (LDHs) have been investigated as potential catalysts for the NOx removal at high temperatures. The best results were obtained with Co–Al mixed oxides derived from LDHs that are active at 750 ◦C in the presence of oxygen and water. These catalysts could reduce or/and decompose the NOx formed in the dense phase of the FCC regenerator, being deactivated at oxygen concentrations higher than 1.5%. Nevertheless this deactivation is not permanent and they would be regenerated after reduction with hydrogen at 530 ◦C. The influence of the layered double hydroxides (LDHs) preparation method on the catalyst activity was studied, observing that t…

Perhepäivähoito laadukkaan varhaiskasvatuksen tarjoajana? : perhepäivähoidon laadunarviointi FCCERS-R-mittarilla

2011

Leppänen, Selina & Peltonen, Ilona. 2011. PERHEPÄIVÄHOITO LAADUKKAAN VARHAISKASVATUKSEN TARJOAJANA? Perhepäivähoidon laadunarviointi FCCERS-R-mittarilla. Pro gradu -tutkielma, Jyväskylän yliopisto, varhaiskasvatuksen yksikkö, 123 sivua sisältäen liitteet 5 kappaletta. Tämä perhepäivähoidon laatua käsittelevä etnografinen tutkimus toi kansainvälisen tuulahduksen suomalaisen perhepäivähoidon laadunarviointiin. Tutkimuksen tarkoitus jakautui kahtaalle. Ensinnäkin tarkoituksena oli selvittää valtakunnallisesti kiinnostusta herättäneen kansainvälisen FCCERS-R-laadunarviointimittarin (Family Child Care Environment Rating Scale Revised edition, Harms, Cryer & Clifford 2007) soveltuvuutta suomalais…
