This paper present some preliminary work on the
\r\npreparation and physicochemical caracterization of nanocomposite
\r\nMFI-alumina structures based on alumina hollow fibres. The fibers
\r\nare manufactured by a wet spinning process. α-alumina particles were
\r\ndispersed in a solution of polysulfone in NMP. The resulting slurry is
\r\npressed through the annular gap of a spinneret into a precipitation
\r\nbath. The resulting green fibres are sintered. The mechanical strength
\r\nof the alumina hollow fibres is determined by a three-point-bending
\r\ntest while the pore size is characterized by bubble-point testing. The
\r\nbending strength is in the range of 110 MPa while the average pore
\r\nsize is 450 nm for an internal diameter of 1 mm and external diameter
\r\nof 1.7 mm. To characterize the MFI membranes various techniques
\r\nwere used for physicochemical characterization of MFI–ceramic
\r\nhollow fibres membranes: The nitrogen adsorption, X-ray
\r\ndiffractometry, scanning electron microscopy combined with X
\r\nemission microanalysis. Scanning Electron Microscopy (SEM) and
\r\nEnergy Dispersive Microanalysis by the X-ray were used to observe
\r\nthe morphology of the hollow fibre membranes (thickness,
\r\ninfiltration into the carrier, defects, homogeneity). No surface film,
\r\nhas been obtained, as observed by SEM and EDX analysis and
\r\nconfirmed by high temperature variation of N2 and CO2 gas
\r\npermeances before cation exchange. Local analysis and characterise
\r\n(SEM and EDX) and overall (by ICP elemental analysis) were
\r\nconducted on two samples exchanged to determine the quantity and
\r\ndistribution of the cation of cesium on the cross section fibre of the
\r\nzeolite between the cavities.<\/p>\r\n","references":"[1] Kalipcilar H, Falconer JL, Noble RD: Preparation of B-ZSM-5\r\nmembranes on a monolith support.
