Abstract

|
Hydrogenated vegetable oil-catalyst mixture(HOCM) was microfiltrated using ceramic membranes to separate the nickel catalyst. The permeate and retentate fluxes of HOCM were measured at the temperature of 40°60 and 80℃, and the average transmembrane pressures (ATP) of 30, 40, 50, 60 and 70 psi. The permeate fluxes increased as both temperature and ATP increased. The membrane fouling and polarization resistances were determined. A volumetric concentration factor (VCF) was used to determine the concentration level of the retentate and how much the volume of feed had been recovered as the permeate. The permeate fluxes of HOCM decreased as nickel concentration in feed increased. An initial decrease in the permeate flux was observed at a VCF value of 1.4, but the magnitude of flow decay was reduced. The nickel contents in both the permeate and the retentate were measured at each VCF. The nickel contents in most permeates at different VCFs were 0.1±0.04 ppm. These results indicate that the ceramic microfiltration membrane system has the potential of removing nickel from the hydrogenated oil-catalyst mixtures.
