Journal ArticleDOI
In situ catalytic upgrading of biomass derived fast pyrolysis vapours in a fixed bed reactor using mesoporous materials
Judit Adam,E.V. Antonakou,Angelos A. Lappas,Michael Stöcker,Merete Hellner Nilsen,Aud M. Bouzga,Johan E. Hustad,Gisle Øye +7 more
TL;DR: In situ catalytic upgrading of biomass derived fast pyrolysis vapours in a fixed bed reactor using mesoporous materials is described in this article, where a fixed-bed reactor is used.
Journal ArticleDOI
Pyrolysis of biomass in the presence of Al-MCM-41 type catalysts
Judit Adam,Marianne Blazsó,Erika Mészáros,Michael Stöcker,Merete Hellner Nilsen,Aud M. Bouzga,Johan E. Hustad,Morten Grønli,Gisle Øye +8 more
TL;DR: In this article, the catalytic properties of Al-MCM-41 type mesoporous catalysts were modified by pore enlargement that allows the processing of larger molecules and by introduction of Cu cations into the structure.
Journal ArticleDOI
Structural determination of a highly stable metal-organic framework with possible application to interim radioactive waste scavenging: Hf-UiO-66
Søren Jakobsen,Diego Gianolio,David S. Wragg,Merete Hellner Nilsen,Hermann Emerich,Silvia Bordiga,Carlo Lamberti,Unni Olsbye,Mats Tilset,Karl Petter Lillerud +9 more
TL;DR: In this paper, the structure of a Hf-UiO-66 metal-organic framework (MOF) was determined using high-resolution synchrotron radiation x-ray powder diffraction (HR-XRPD) combined with Hf $L$3-edge extended xray absorption fine structure.
Journal ArticleDOI
Investigation of the effect of metal sites in Me–Al-MCM-41 (Me = Fe, Cu or Zn) on the catalytic behavior during the pyrolysis of wooden based biomass
Merete Hellner Nilsen,Merete Hellner Nilsen,E.V. Antonakou,Aud M. Bouzga,Angelos A. Lappas,Karina Mathisen,Michael Stöcker +6 more
TL;DR: In this article, the mesoporous material Al-MCM-41 has been reported to exhibit interesting catalytic properties during the pyrolysis of wooden-based biomass, and the results showed that the type of metal is of more importance than the metal siting.
Journal ArticleDOI
XAS (XANES and EXAFS) Investigations of Nanoparticulate Ferrites Synthesized Continuously in Near Critical and Supercritical Water
Merete Hellner Nilsen,Camilla Nordhei,and Astrid Lund Ramstad,David G. Nicholson,Martyn Poliakoff,Albertina Cabañas +5 more
TL;DR: In this paper, the inverse spinel structures extend to the nanoregime, and the results of X-ray absorption near-edge spectroscopy (XANES) and extended Xray absorption fine structure (EXAFS) were used to determine the type of spinel structure.
