Kinetic Study of the Catalytic Desorption of Carbon Dioxide (CO2) from CO2-Loaded Monoethanolamine (MEA) and Blended Monoethanolamine-Methyldiethanolamine (MEA-MDEA) during Post Combustion CO2 Capture from Industrial Flue Gases
… showed that HZSM-5 catalyst with higher Brønsted/Lewis acid site ratio exhibited dual site adsorption mechanism and provided faster kinetics and higher conversions with lower activation energy in comparison with γ-Al2O3 for both solvents. Also, a statistical analysis using four catalysts, namely, …

INDUCING ACTIVE SITES IN CLUSTERS: REACTIVITY OF Al13Ix- and Al14Iy- (x=0-2, y=2-4) WITH METHANOL
… in pure aluminum cluster anions as a result of Lewis acid and base pairs. Using this a starting point, the goal of this study has been to explore how reactivity is affected with the addition of one or more ligand, which may induce active sites on the surface of the metal clusters. To study this, …

An Examination of γ-valerolactone Ring Opening and Decarboxylation in Multiphase System and Over Various Solid Acid Catalysts
… commercial potentials. Of interest here is the acid-catalyzed ring opening of GVL to form pentenoic acid (PEA) isomers and following decarboxylation to produce butenes. In this study, GVL ring opening, and decarboxylation are examined in both liquid and gas phases over various catalytic systems …

A study of active sites on fibrillar alumina catalysts
… the concentration and chemical nature of active sites on two kinds of fibrous alumina catalysts. The results of this investigation are comparable to results reported in the literature describing similar reactions studied over more conventional forms of gamma alumina. However, there were a few …

Catalytic implications of confined solvent ensembles within Lewis acid zeolites
Lewis acidic zeolites are microporous crystalline materials that offer promise as catalysts for the activation and conversion of biomass-derived precursors in the liquid-phase due to their unique water-tolerance and synthetic versatility. The active site environment in zeolite catalysts is …
