Xylene isomerization in a ZSM-5/SS membrane reactor
(Springer, 2008-06)
A membrane reactor containing different types of ZSM-5/porous SS membranes was used to perform the xylene isomerization reaction. The parent Na-ZSM-5 layer was synthesized by secondary growth on top of porous stainless ...
Xylene isomerization in a membrane reactor. Part I: The synthesis of MFI membranes for the p-xylene separation
(Elsevier Science Sa, 2006-09)
The synthesis and characterization of silicalite and ZSM-5 films supported on porous SS tubes are described. Composite membranes were used to separate xylene isomers between 150 and 400 °C. Permeation measurements of the ...
Isomerización de xilenos en reactores de membrana: síntesis y evaluación de membranas compuestas tipo MFI
(2007-03-23)
Zeolite membranes are very well positioned for use in industrial membrane reactors due to their thermal and chemical stability. They are particularly useful to improve conversion, selectivity and yield in equilibrium-limited ...
Caracterização e propriedades catalíticas da zeolita HZSM5 modificada com nióbio
(Sociedade Brasileira de Química, 1997-02-01)
HZSM5 zeolite was modified by exchanging proton by niobium (V). Several samples were obtained with various degrees of exchange. Pore volumes and acidity were measured to characterize these exchanged zeolites. Catalytic ...

Synthesis and X-ray structure of the rhenium methyl complex trans-Cp*Re(CO)(2)(Me)I and a study of the products of photolysis of the rhenium alkyl methyl and dimethyl complexes Cp*Re(CO)(2)(Me)R (R = Ph, p-tolyl, Me) under CO
(American Chemical Society, 1999-02)
Reaction of Cp*Re(CO)(2)I-2 with methylcopper affords cis-Cp*Re(CO)(2)(Me)I, which converts to the trans isomer on prolonged reaction or in the presence of neutral alumina. The X-ray structure of the trans isomer has been ...
