Non-PGM Iron Perovskite Three-Way Gasoline Emissions Control Catalysts: Kinetics, Reaction Mechanism and Catalyst Sizing Study

Autor: Andrew P. E. York, Sam K. Wilkinson, Crispin Cooper, Kerry Simmance

Publikováno v: Topics in Catalysis. 63:256-267

An A-site deficient perovskite material, namely La0.8FeO3, has been tested as a catalyst for the reduction of nitrogen oxide with carbon monoxide. The activity of the La0.8FeO3 has been compared with that of a low loaded supported Rh catalyst. Kineti

Pd/Al2O3 catalysts are known to be active for the low temperature methane oxidation reactions, however it has been shown that a number of gases normally associated with methane gas streams (H2O, CO2, H2S) can have an inhibitory effect on the total ox

Understanding methanol synthesis from CO/H2 feeds over Cu/CeO2 catalysts

Autor: Leon G.A. van de Water, Sam K. Wilkinson, Watson Michael John, Richard A.P. Smith

Publikováno v: Journal of Catalysis. 364:57-68

Understanding copper-based methanol synthesis catalysts as a function of catalyst type and applied reaction conditions is an area of active industrial and academic research. In this work, results of a methanol synthesis study over a Cu/CeO2 catalyst

A parametric evaluation of powder flowability using a Freeman rheometer through statistical and sensitivity analysis: A discrete element method (DEM) study

Autor: Sam K. Wilkinson, E.H. Stitt, Michele Marigo, S.A. Turnbull, Z. Yan

Publikováno v: Computers & Chemical Engineering. 97:161-174

The flowability of powders in a Freeman Rheometer (FT4) is explored in this study using discrete element method (DEM). Five DEM input parameters describing particle properties: static and rolling friction coefficients, coefficient of restitution, You

Kinetic modelling of thermal processes using a modified Sestak-Berggren equation

Autor: John West, Rebecca L. Gibson, Robert W. Gallen, Sam K. Wilkinson, Mark J.H. Simmons, E. Hugh Stitt

Publikováno v: Chemical Engineering Journal. 408:127318

This study outlines the principles of modelling the kinetics of solid-state reactions through the simultaneous fitting of multiple peak curves using the modified Sestak-Berggren equation. This mathematical model gives an indication of the mechanism o

Investigating mixing and segregation using discrete element modelling (DEM) in the Freeman FT4 rheometer

Autor: Sam K. Wilkinson, E.H. Stitt, Zilin Yan, Michele Marigo

Publikováno v: International Journal of Pharmaceutics. 513:38-48

Mixing and segregation in a Freeman FT4 powder rheometer, using binary mixtures with varied particle size ratio and volume fraction, were studied using the Discrete Element Method (DEM). As the blade moves within the particle bed, size induced segreg

Discrete element modelling (DEM) input parameters: understanding their impact on model predictions using statistical analysis

Autor: Sam K. Wilkinson, Z. Yan, Michele Marigo, E.H. Stitt

Publikováno v: Computational Particle Mechanics. 2:283-299

Selection or calibration of particle property input parameters is one of the key problematic aspects for the implementation of the discrete element method (DEM). In the current study, a parametric multi-level sensitivity method is employed to underst
