      Look like a suitable alternative to use as raschig rings (if you wanted to
      go down that path). They'll have less surface area per volume than
      scrubbers (thus not give the same performance - eg you'll need a taller
      column to get the same results as now), but likewise will be less prone to
      clogging up with gunge - say you find that your column is really sensitive
      about keeping clean or else it floods on you. I don't think being porous is
      a good thing - it wont aid the alcohol-water interchange unless you can get
      both the vapour & reflux to be in the pores together at the same time
      (unlikely ?).

      Tony
