The mesoporous molecular sieves of MCM-41 and AlMCM-41 type are considered as promising support for metal in the refining processes of petroleum-based materials as catalysts and adsorbents for environmental protection. In ...
Síntese e caracterização de materiais nanoporosos para pirólise catalítica de óleos pesados
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2008-12-22)
The present work reports the study of nanoporous structures, aiming at their use in research directed to the current demand of the petroleum industry to value heavy oil. Initially,
two ways were chosen for the synthesis ...
Evaluación de la capacidad de captura de CO₂ mediante materiales mesoporosos de sílice modificados
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2015)
La capacidad de captura de CO₂ a baja presión (<100 kPa) y baja temperatura (298 K) se investigó en cuatro materiales mesoporosos MCM-41, uno sin modificación y tres modificados por síntesis directa con un metal (M); la ...
Evaluation of MCM-2 expression in TMA cervical specimens
(Public Library of Science, 2017)
Selective oxidation of benzyl alcohol through eco-friendly processes using mesoporous V-MCM-41, Fe-MCM-41 and Co-MCM-41 materials
(Elsevier Science, 2017-07-25)
MCM-41 nanostructured materials modified with Vanadium, Iron and Cobalt were synthesized by a hydrothermal method. The catalysts were characterized by XRD, UV–Vis-DR, ICP-OES and N2 adsorption. All the catalysts showed ...
