eolite synthesis out of fly ash is a worth noticing, low budget alternative
for the production of zeolites compared to natural zeolites or zeolites
produced from pure chemicals. Generally, zeolites due to their structure
represent interesting properties (ion-exchange, catalytic, sorptive). Based
on the sorption properties it is possible to use this material as a sorbent
for flue gases impurities such as carbon dioxide. Energy sector in Poland is
mainly based on burning of brown and hard coal. Environmental concerns
and legal aims oblige to reduce the emission of greenhouse gases emitted
to the atmosphere. Due to restrictions on the emission limits, it is crucial to
search for differentiated methods for CO
2
capturing adapted for the economy
new needs. The use of zeolites such as sorbent in the industrial processes
may have a positive ecological result, not only due to the elimination of
disadvantages of commonly used CO
2
capture absorption methods, but also
due to the usage of waste material as a raw material for the synthesis. Fly
ash zeolites may be synthesised by different methods which affect the final
product. It influences the type and amount of zeolite present in the synthesized
sample and in this way the sorption properties of synthesized materials. In this
work, the comparison of CO
2
sorption of 3 fly ash zeolites samples synthesized
by differentiated methods were presented. Synthesis methods chosen were:
hydrothermal method, fusion method and modified two-step method. Results
indicated different sorption capacity due to zeolite type present, synthesis
efficiency and for similarities in isotherm shapes connected with the presence
of micropores.
