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 ...
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 ...
Cost and pollution by the use of xylene in cervical cytology in four Peruvian hospitals
(Science and Information OrganizationGB, 2022-06-08)
"Background: Cytological samples are cleared with xylene in two or three baths during a Pap test, however, this solvent has a high degree of toxicity, and being a controlled reagent infers high costs for its purchase and ...
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. ...
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 ...
Advanced oxidation processes for elimination of xylene from waste gases
(Elsevier Science SA, 2020-11)
The elimination of xylene was experimentally studied using advanced oxidation process in a two-step pilot plant photochemical unit with the use of UV irradiation combined with ozone (first step) and with hydrogen peroxide ...

Pt-Re-Ge/Al 2O 3 catalysts for n-octane reforming: Influence of the order of addition of the metal precursors
(Elsevier Science, 2012-03)
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 ...
