A durable ZSM-5/SS composite tubular membrane for the selective separation of p-xylene from its isomers
(Elsevier Science, 2006-09)
A ZSM-5 membrane synthesized on a stainless steel porous tube was used for the separation of p-xylene from its isomers, m- and o-xylene. The membrane was prepared by secondary growth on the outer surface of the support. ...
Influence of exchanged cations (Na+, Cs+, Sr2+ and Ba2+) on xylene permeation through ZSM-5/SS tubular membranes
(Elsevier Science, 2008-07)
Na-ZSM-5 membranes were synthesized by secondary growth on the outer surface of stainless steel porous tubes. The membranes were ion-exchanged with Cs+, Ba2+ and Sr2+ to investigate their effect upon the separation of ...
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 ...
Experimental vapor-liquid equilibria data for binary mixtures of xylene isomers
(Associação Brasileira de Engenharia Química, 2005-07)
Separation of aromatic C8 compounds by distillation is a difficult task due to the low relative volatilities of the compounds and to the high degree of purity required of the final commercial products. For rigorous simulation ...
Obtenção de organovermiculitas utilizando tensoativos e microemulsões e suas aplicações na separação de isômeros do Xileno
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2014-02-27)
Surfactants are versatile organic compounds that have, in a single molecule, double chemical affinity.
The surfactant molecule is composed by a hy

Pt–Re–Ge/Al2O3 catalysts for n-octane reforming: Influence of the order of addition of the metal precursors
(2012)
Trimetallic Pt–Re–Ge supported catalysts for naphtha reforming were prepared by successive impregnation of suitable precursors on gamma alumina. The order of addition of these precursors was varied and its influence on the ...
