The Couette-Taylor Flow (CTF) reactor characterized by the high values of t
he volumetric mass transfer coefficients (of the order of 10(-1) s(-1)) and
a large specific interfacial area has been presented. The mass transfer ex
perimental results of benzaldehyde oxidation have been shown. To intensity
the mass transfer the eccentric Couette-Taylor Flow reactor has successfull
y been tested. The mass transfer coefficients determined for the eccentric
CTF reactor were significantly higher than those found in the centric CTF r
eactor. The proposals to apply the CTF reactor to oxidise organic liquids a
nd contaminants have been discussed.
