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 ...
Enhancement of synthesis of ZSM-11 zeolite by microwave irradiation
(Elsevier Inc, 2014-07)
A novel and complete description for ZSM-11 zeolite microwave-assisted synthesis is provided. The time required for the synthesis of ZSM-11 zeolite was remarkably reduced down to 3–4 days instead of 14 days under classical ...

H-ZSM-11 and Zn-ZSM-11 zeolites and their applications in the catalytic transformation of LDPE
(Elsevier Science, 2009-09)
Low density polyethylene was converted into hydrocarbons over Zn- and H-ZSM-11 zeolite catalysts in a fixed-bed reactor during 20 and 60 min reaction time, 0.5 and 2.0 polymer to catalyst mass ratio at 500 °C. The zeolites ...
Zéolitas ZSM-12 mesoporosas textura, cristalinidade e atividade ácida para o craqueamento de cicloexano
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2013-09-12)
The research addressed the generation of mesoporosity in the zeolite ZSM-12 (MTW). In the first part we studied the synthesis of ZSM-12 via conventional methodology and in the presence of a mesopore directing agent, ...

Isomerização do n-Hexano por platina suportada na zeólita H-ZSM-5 : efeito do teor de alumínio
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2011-08-01)
The objective of this study was to verify the influence of the Si/Al ratio (11.5, 15.0, 25.0, 40.0 and 140.0) in zeolite ZSM-5 in the conversion, activity, selectivity and stability as bifunctional catalysts (Pt/H-ZSM-5) ...
Estudio sobre la influencia de la incorporación de catión metálico en la actividad catalítica y comportamiento magnético de zeolitas zsm-5Study on the influence of the metal cation incorporation in the Catalytic activity and magnetic behavior of ZSM-5 zeolites
(Universidad Internacional de la Empresa, 2011-03)
Se sintetizaron zeolitas ZSM-5 con relación molar Si/Al 17 por el método hidrotérmico, las que fueron modificadas con cobalto y cromo por la técnica de impregnación por vía húmeda en un 3 % p/p del metal. Los resultados ...
Optimized benzaldehyde production over a new Co-ZSM-11 catalyst: Reaction parameters effects and kinetics
(Elsevier Science, 2014-02)
An efficient Co-ZSM-11 catalyst has been synthesized for benzaldehyde production by the selective styrene oxidation. Reaction parameters such as catalyst mass, reaction temperature, molar ratio styrene/hydrogen peroxide ...
