The aim of this work is to evaluate the characteristics of an activated carbon obtained
from unburnt carbon in coal fly ashes to be used in the removal of NO. Carbon-rich
fraction was obtained by mechanical sieving of fly ashes. The mineral matter was
removed by conventional HCl and HF desmineralization procedure. Activation was
carried out with steam at 900ºC in order to develop porosity onto the sample.
Characterization of samples was performed by several techniques with a main objective:
to follow the mineral matter content, composition and distribution on the samples in
order to better understand how to remove it from unburnt carbon in fly ashes.
To study the use of this unburnt carbon as a precursor for the preparation of activated
carbons for gas cleaning, the NO removal by ammonia using activated carbon as a
catalyst at low temperature was performed. Results show a good performance of
activated carbon in this reaction that is in relationship with BET surface area. |
