The effect of CO2 in biomass synthesis gas is also investigated.

    15. Influence of the Sparger Type and Added Alcohol on the Gas Holdup of an External-Loop Airlift Reactor (pages 701–708)

      Predrag S. Kojić, Milenko S. Tokić, Ivana M. Šijački, Nataša Lj. Lukić, Dragan Lj. Petrović, Dragica Z. Jovičević and Svetlana S. Popović

      Article first published online: 24 FEB 2015 | DOI: 10.1002/ceat.201400578

      Thumbnail image of graphical abstract

      The effects of alcohol and three different gas spargers on the gas holdup in external-loop airlift reactors were studied. The sinter plate turned out to be the most efficient sparger. Small amounts of common aliphatic alcohols increased the gas holdup due to their coalescence-inhibiting nature. The proposed artificial neural network has the potential to predict the gas holdup in airlift reactors.
