    Notes: Wall-to-bed heat transfer coefficients in three-phase fluidized beds with glass beads and clyindrical γ-alumina particles were determined experimentally. In the present study, the relative increase in heat transfer coefficient was found equal to the relative decrease in liquid holdup in three-phase fluidized beds. Modified Stanton number has been correlated with modified Reynolds number.

    Notes: Liquid holdups and wall-to-bed heat transfer coefficients in three-phase fluidized beds with glass beads and cylindrical γ-alumina particles were determined experimentally. It was found that the product of heat transfer coefficient and liquid holdup in three-phase fludized beds is equal to that in corresponding liquid-solid fluidized beds. A generalized correlation equation for heat transfer coefficients in both liquid-solid and three-phase fluidized beds was proposed based on the above relationship.

    Description / Table of Contents: Zusammenfassung Die Gaschromatographie von Naturstoffen wird durch nicht-flüchtige Anteile sehr erschwert. Störungen erfolgen durch Krackung und Katalysatorwirkung im Einspritzblock, Geisterpeaks und Grundlinienversatz. Mittels einer einfachen Gelchromatographie-Vortrennung wird eine Verbesserung der Citrusölanalytik beschrieben. Werden die höhermolekularen Stoffe nicht benötigt, kann man diese durch Verwendung einer Vorsäule am Gaschromatographen ausschalten. Ein einfacher Umbau am GC Gerät wird angegeben.
    Notes: Summary GC separation of natural products is upset by nonvolatile compounds. The problems arise from thermal and catalytic cracking in the injector, from ghost peaks and base line drift. A treatment is shown for obtaining an improvement in citrus analysis by using simple gelpermeation chromatography for pre-separation. A second method describes the separation of the high relative molecular mass compounds with a pre-column GC-equipment. A simple conversion is demonstrated for this modification of GC apparatus.
