Papeles cerámicos catalíticos basados en cobalto y cerio impregnados con el método de spray húmedo para ser empleados en filtros de partículas diésel
(2021-11-05)
Este trabajo de tesis está orientado al desarrollo de catalizadores estructurados, específicamente papeles cerámicos catalíticos, para su aplicación como filtros de partículas emitidas por motores diésel. Para la preparación ...
Development of sepiolite/SiC porous catalytic filters for diesel soot abatement
(Elsevier Science, 2016-08)
Honeycomb monoliths made up of 70 wt.% sepiolite and 30 wt.% SiC were prepared and macropores were generated in the honeycomb structure by introducing a temporary additive with the aim of obtaining an adequate porosity to ...
Determinación del porcentaje optimo de biodiésel y diésel filtrado a 2850 msnm, para reducir la opacidad de un motor con sistema CRDI, y reducir el impacto ambiental
