Fe-ZSM-5 og Fe-SAPO-34 Katalysatorer for Lavtemperatur Selektiv Katalytisk Reduksjon av NOx med NH3
Landfald, Lisa Leganger (Master thesis, 2019)Jernbaserte katalysatorer med zeolitten ZSM-5 og zeotypene konvensjonell SAPO-34 og hierarkisk SAPO-34 som bærere ble laget for å undersøke katalytiske opptredenen for selektiv katalytisk reduksjon av NOX med NH3 ved lavere ... -
New catalysts for low-temperature selective catalytic reduction (SCR)
Bjørkedal, Ole Håvik (Master thesis, 2016)Mesoporous alumina with a regular pore structure and high surface area was prepared using a sol-gel method with a structure-guiding surfactant. The typical diameter of the pores were measured to be 4-6 nm, with narrow pore ... -
One-pot synthesis of highly dispersed mesoporous Cu/ZrO2 catalysts for NH3-SCR
Bjørkedal, Ole Håvik; Regli, Samuel K.; Nuguid, Rob Jeremiah G.; Vullum, Per Erik; Kröcher, Oliver; Ferri, Davide; Rønning, Magnus (Peer reviewed; Journal article, 2021)Catalysts consisting of highly dispersed copper on a mesoporous ZrO2 support were synthesised via a one-pot sol-gel synthesis and were tested for the selective catalytic reduction of NOx by NH3. The copper dispersion was ... -
Single-stage synthesis of highly dispersed copper and iron oxides on mesoporous supports for NH3-SCR
Bjørkedal, Ole Håvik (Doctoral theses at NTNU;2024:299, Doctoral thesis, 2024)Selective catalytic reduction (SCR) of nitrogen oxides (NOx) is a process where NOx is reduced to nitrogen (N2) by use of a reducing agent. One common reducing agent is ammonia (NH3-SCR). Increasingly stricter regulation ...
