Catalisadores Cu-, Co- ou Fe-ZSM-5 caracterização e avaliação na redução de NO a N2 com hidrocarbonetos na presença ou ausência de vapor de água.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2005-03-04)
The minimization of the emissions of nitrogen oxides (NOx) in the atmosphere has been one of the great goals in the area of environmental
protection. Among the possible processes to treat the NOx, the selective catalytic ...
ZSM5 growth on a FeCrAl steel support. Coating characteristics upon the catalytic behavior in the NOx SCR
(Elsevier Science, 2008-10)
The search for more efficient catalytic processes requires the development of new structured catalytic systems. Along these lines, a study was conducted to produce and characterize a structured catalyst composed of an ...
Characterization of FeMCM-41 and FeZSM-5 catalysts to styrene production
(Elsevier, 2002-04)
FeMCM-41 and FeZSM-5 catalysts have been prepared and tested in the
dehydrogenation of ethylbenzene to produce styrene. These new catalytic systems have high specific areas and can stabilize the trivalent state of iron. ...
Ethylene polymerization using dealuminated ZSM-2 zeolite nanocrystals as an active metallocene catalyst support
(ELSEVIER, 2008-09-15)
The preparation of dealuminated (DEAL) ZSM-2 zeolite nanocrystals for use as an active metallocene polymerization catalyst support is presented. The DEAL-ZSM-2 zeolite form was prepared by using steam treatment; metallocene ...
Fe/ZSM-11 as a novel and efficient photocatalyst to degrade Dichlorvos on water solutions
(Elsevier Science, 2017-03)
Iron modified ZSM-11 zeolites were tested as heterogeneous catalysts in the photodegradation of Dichlorvos water solutions. ZSM-11 zeolite matrixes were synthesized by the hydrothermal method and iron was incorporated by ...
