n this work, biopolymer/ceramic hollow fibers were manufactured at high yield using a modified polyol process in spinneret
set-up and allowed to adsorb controllable amounts of Cu
2+
. The fibers were further converted to catalytic Cu decorated,
carbon/ceramic composite hollow fibers (C/Al

) by a post-sintering technique. The polyol process modification pertained
to the use of alginate as the metal ion binder and metallic nanoparticles stabilizer. The walls of the hollow fibers were porous,
exposing a high surface area decorated with Cu nanoparticles. The structural and morphological properties of the obtained
catalytic composite hollow fibers have been studied and their DeNO
x
abatement efficiency has been evaluated via continuous
flow process we propose here, with the gas stream sweeping the shell and lumen side of a bundle of the fibers in the tangential
flowmode. The stability, long working-life and easy regeneration of the composite catalytic fibers were studied in relation to the
carbonaceous content and the possible deactivation/reactivation mechanisms. It has been concluded that carbon contributed
significantly to the improvement of the DeNO
x
activity, especially in the cases, where reducing gases such as CO were absent
from the gas stream. Moreover, the DeNO
x
efficiency was high and stable for more than 300 hours on stream, a feature which
combined with the viability in terms of manufacturability and yield, makes us propose these catalytic fibers and the respective
bundle type reactor as the next generation technology for NO abatement.
