Cortés, Joaquín; Valencia Astorga, Eliana; Herrera, Jorge; Araya Figueroa, Paulo (AMER CHEMICAL SOCIETY, 2007-05)By means of a mechanism similar to that used by Peden and Permana for the reduction reaction of NO by CO on Rh and the analytical solution of its kinetics equations, a set of kinetics parameters that interpret some experimental ...

Araya Figueroa, Paulo; Guerrero, Sichem; Robertson, J.; Gracia, F. J. (ELSEVIER SCIENCE BV, 2005-04-08)The combustion of methane has been studied over 1% Pd catalysts supported on commercial silica with different hydrophobicity, prepared by chlorine free precursors. It was found that, when no water is added to the feed, the ...

Guerrero, Sichem; Araya Figueroa, Paulo; Wolf, Eduardo E. (ELSEVIER, 2006-01-10)The results presented in this work clearly show that zirconia synthesized by precipitation of zirconyl chloride with NaOH leads to a zirconia with high surface area (224 m(2)/g), which is relatively stable after high ...

Cortés, Joaquín; Valencia Astorga, Eliana; Araya Figueroa, Paulo (SPRINGER,, 2006-11)A Monte Carlo (MC) simulation is carried out of the catalytic oxidation of methane based on the pseudo-Langmuir-Hinshelwood (LH) mechanism proposed by Iglesia et al., that attempts to interpret the behavior of this reaction, ...

Cortés, Joaquín; Valencia Astorga, Eliana; Araya Figueroa, Paulo (Springer, 2013)kinetic Monte Carlo simulation algorithm and a theoretical mean field study of two sites is developed to interpret a redox mechanism based on that proposed by Sedmak et al. for the oxidation of CO over the nanostructu ...

Cortés Garrido, Joaquín; Valencia Astorga, Eliana; Araya Figueroa, Paulo (Elsevier, 2016)Monte Carlo simulations for the productivity and order of the PROX/copper-ceria catalyst reaction with different superficial %Cu are made. The results are correlated with the behavior of the different surface species (CO, ...

Queirolo Córdova, Ariel Andrés (Universidad de Chile, 2008)El objetivo principal de esta memoria es la creación de un modelo matemático para poder simular el comportamiento de un reactor flujo pistón (PFR) de lecho fijo catalítico de zirconia para el caso de la reacción de ...

Díaz Alvarado, Felipe Andrés (Universidad de Chile, 2012)El Hidrógeno puede ser utilizado en una Batería Continuamente Alimentada para generar potencia eléctrica, y ha sido propuesto como una opción atractiva para la sustitución de combustibles fósiles, especialmente cuando es ...

Cortés, Joaquín; Valencia Astorga, Eliana; Aguila, Gonzalo; Orellana, Esteban; Araya Figueroa, Paulo (SPRINGER, 2008-11)An experimental study is made of the time decay of activity of the CO-NO reaction on a Pd/Al2O3 looking at the effect on reaction order and apparent activation energy. The optimum kinetics parameters fitting the steady ...

Salinas, Daniela; Guerrero, Sichem; Araya Figueroa, Paulo (ELSEVIER, 2010)The transesterification reaction of canola oil was studied on titania-supported catalysts with varying loadings of potassium. It was found that the most active catalysts fall in the range where the adsorption/ desorption ...
