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 ...
Degradação de geomembranas de polietileno de alta densidade (HDPE) após exposição à intempérie e lixívia
(2010)
This paper presents some results of MFI and OIT tests performed on HDPE geomembranes of 0,8 and 2,5 mm that were exposed to weathering effects and leachate after 30 months (2,5 years). The aim of this work is the evaluation ...
Use of gene expression profile to identify potentially relevant transcripts to myofibrillar fragmentation index trait
(2020-07-01)
The myofibrillar fragmentation index (MFI) is an indicative trait for meat tenderness. Longissimus thoracis muscle samples from the 20 most extreme bulls (out of 80 bulls set) for MFI (high (n = 10) and low (n = 10) groups) ...
CHARACTERIZATION OF MFI ZEOLITE MEMBRANES BY MEANS OF PERMEABILITY DETERMINATION OF NEAR CRITICAL AND SUPERCRITICAL C0(2)
(Sociedad Chilena de Química, 2008)
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 ...
Síntese e caracterização de membranas zeolíticas tipo mfi e aplicação em separação de aromáticos
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2013-07-22)
The synthesis of MFI-type zeolite membranes was carried by the process in situ or
hydrothermal crystallization. We studied the homogenization time of the room
temperature and gel filtration just before the crystallization ...
Preparation of stable MCM-48 tubular membranes
(Elsevier Science, 2009-01)
Stable mesoporous membranes with a cubic structure, based on the MCM-48 material, were successfully prepared on alumina supports by hydrothermal synthesis, starting from sols having both CTABr and TPAOH structure directing ...
