dc.description.abstract
The continuous expansion of civil society, with the change in lifestiles and resources
use, leads necessarily to an higher impact of the industrial facilities on the surrounding
environments. As it is well known, nowadays CO2 emissions are still one of the major effects of
industrial pollution. The aim of this work is to show that composites zeolite/carbon materials could
act as useful CO2 adsorbants in the field of environmental preservation. Examples of such materials
are widely used for the most diverse application, ranging from stabilizers for electrochemical
batteries to enhance in thermal energy storage, or also for treatment of industrial waste water [1].
Usually, the approach that is used to obtain such composites is to disperse a precise amount of
carbon from different sources (palm oil, coal, rice hulls, …) directly on the zeolite support.
Experimental/methodolgy. Here we propose a direct synthesis of the NaY zeolite with 3 different
carbon sources (activated carbon - AC, carbon black - CB and graphite - GP) by hydrothermal method
aimed at obtaining microcrystal-sized and nanocrystal-sized samples. In general, all ours samples
have been characterized by SEM, FT-IR, XRD, TGA, N2-physisorption and TPD techniques.
Results and discussion. Similar approaches already showed enhanced CO2 adsorption properties in
the case of carbon black composite with a zeolite 13X [2],
while carbon black itself usually needs to be activated by
surface modification (or coating) with an adequate CO2
adsorbant [3]. This is consistent with ours result, as the pure
carbon phases that have been used for the composites didn’t
show any CO2 adsorption property at the investigated
temperature before being coupled with the NaY zeolite. After
confirming the Faujasite crystalline phase of each composite
by XRD, SEM pictures showed an higher average diameter of
the NaY-AC with respect to the other samples. However, TPD
measurements of this sample exhibits amounts of adsorbed
CO2 that are quite comparable to the pure NaY zeolite, while
in the case of the other composites this increase showing
higher CO2 adsorption performances for the NaY-CB and
finally the best for the NaY-GP composite.
