Ni/MCM-41 y Co/MCM-41 como catalizadores Fenton heterogéneos en la degradación de tartrazina
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2021)
MCM-41 con Ni y Co soportados (a diferentes relaciones Si/metal) se prepararon con la finalidad de estudiar su efecto en la degradación de tartrazina (Amarillo-5) en solución acuosa con ayuda de peróxido de hidrógeno en ...
Effect of the catalyst MCM-41 on the kinetic of the thermal decomposition of poly(ethylene terephthalate)
(Springer, 2010-02-01)
The aim of this work is to determine the activation energy for the thermal decomposition of poly (ethylene terephthalate)-PET, in the presence of a MCM-41 mesoporous catalyst. This material was synthesized by the hydrothermal ...

Avaliação do catalisador CTA-MCM-41, modificado por poliacrilatos, na transesterificação de monoéster
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2014-03-24)
The silica hybrid CTA-MCM-41 (where CTA is the cetyltrimethylammonium cation) was synthesized and used in the transesterification of ethyl acetate with methanol. This is a model reaction used to test basic catalysts for ...
Avaliação da remoção de hidrocarbonetos aromáticos (BTEX) em águas utilizando materiais nanoestruturados do tipo Ti-MCM-41
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2012-01-30)
Volatile Organic Compounds are pollutants coming mainly from activities that use fossil fuels. Within this class are the BTEX (benzene, toluene, ethylbenzene and xylenes) compounds that are considered hazardous. Among the ...
