Effectiveness factor calculation and monolith reactor simulation with non-uniform washcoat and arbitrary catalytic activity distribution
(Plapiqui, 2011-01)
A simple, precise and fast procedure to simulate monolith reactors is presented. The method allows the estimation of effectiveness factors (η) in monolith with washcoat of irregular geometries and arbitrary catalytic ...
Non-uniform size of catalyst particles. Impact on the effectiveness factor and the determination of kinetic parameters
(Elsevier Science SA, 2020-09)
The analysis of the effectiveness factor in catalytic particles with non-uniform size, was performed. The procedure proposed by Weisz and Prater to determine the intrinsic kinetic constants from experimental results was ...
Mathematical model for the calcination of CaCO3 under oxy-fuel combustion atmosphere
(2017-04-09)
In this thesis, the calcination of CaCO3 under oxy-fuel combustion atmosphere is modeled. At first, a reaction model that simultaneously takes into account the non-uniformity in the solid microstructure and the sintering ...
Synthesis of manganese porphyrinosilica imprinted with templates using the sol-gel process
(2000-08-01)
The optimized conditions for the preparation of a new manganese porphyrinosilica-template material are reported. The manganese porphyrinosilica-template was prepared by the sol-gel process, by the reaction of -SO2Cl groups ...

Óxidos de Metales de Transición como catalizadores para la oxidación total de Compuestos Orgánicos Volátiles (COVs) en fase gaseosa
(Bogotá - Ciencias - Maestría en Ciencias - QuímicaDepartamento de QuímicaUniversidad Nacional de Colombia - Sede Bogotá, 2019-11-30)
En general los óxidos de metales de transición (OMT) se posicionan como materiales con actividad catalítica apreciable en la oxidación total de compuestos orgánicos volátiles (COVs), con altos porcentajes de conversión y ...
Incorporation of nanostructured ReO3 in silica matrix and their activity toward photodegradation of blue methylene
(Springer, 2020)
ReO3 were prepared by thermal treatment of the macromolecular Chitosan center dot(ReCl3)(X) and PSP-4-PVP center dot(ReCl3)(X) precursors. The plasmon band in the visible region for the as obtained ReO3 from their visible ...
