Characterization and comparison of hydrophilic and hydrophobic room temperature ionic liquids incorporating the imidazolium cation
Jonathan G. Huddleston,Ann E. Visser,W. Matthew Reichert,Heather D. Willauer,Grant A. Broker,Robin D. Rogers +5 more
TL;DR: A series of hydrophilic and hydrophobic 1-alkyl-3-methylimidazolium room temperature ionic liquids (RTILs) have been prepared and characterized to determine how water content, density, viscosity, surface tension, melting point, and thermal stability are affected by changes in alkyl chain length and anion.

Olefinic Oligomer and Cosolvent Effects on the Coking and Activity of a Reforming Catalyst in Supercritical Reaction Mixtures
TL;DR: In this article, it was shown that peroxide removal from the hexene feed and cosolvent addition can significantly improve isomerization rates, catalyst activity maintenance, and pore accessibility in supercritical reaction mixtures.
Journal ArticleDOI
Catalyst activity maintenance or decay: A model for formation and desorption of coke
TL;DR: In this paper, a new kinetic model was proposed to describe how coke formation, adsorption, and desorption can lead to catalyst activity maintenance or decay in reaction mixtures.
Journal ArticleDOI
Influence of Local Structural Correlations on Free-Radical Reactions in Supercritical Fluids: A Hierarchical Approach
TL;DR: In this paper, the authors investigated the effect of local solvent structure on a model free-radical reaction and found that locally high solvent densities around reactants at subcritical bulk densities enhance the rate constant for Heisenberg spin exchange in supercritical fluids.
Journal ArticleDOI
Vanadia-Titania Aerogels: III. Influence of Niobia on Structure and Activity for the Selective Catalytic Reduction of No by NH3
TL;DR: Niobia-doped vanadia-titania aerogels with 20 wt% nominal V2O5 and 2-6 wt % nominal Nb2O 5 have been prepared by a two-stage solgel process with subsequent supercritical drying as discussed by the authors.

Hydrogenation of fats and oils at supercritical conditions
Magnus Härröd,Poul Møller +1 more
TL;DR: In this article, the authors discussed the hydrogenation of fats and oils at supercritical conditions, where a solvent miscible with both oil and hydrogen is used to form a substantially homogeneous phase to pass the catalyst surface.
