It is being observed that average temperature on Earth increases each year. This phenomenon can be explained by a theory
known as a greenhouse effect. Thermal radiation, which is being emitted from the Earth’s surface, is being absorbed
by molecules in the atmosphere. Mainly, these molecules are methane, carbon dioxide and water vapor. The greater their
concentration in the atmosphere, the more thermal radiation is being absorbed. To mitigate further intensification of the
greenhouse effect by reducing CO2 emission, some technologies are being developed. They are known as a Carbon Capture
and Storage (CCS). One of those technologies is post-combustion capture of CO2 on solid sorbents, like activated carbon (AC).
AC is a porous material with well developed specific surface area. It is obtained through carbonization of a precursor with
predominating carbon element and next activation- physical, chemical or combined. Depending on precursor’s source, the
amount of impurities, also known as ash, in final AC may vary from less than 1 wt% to even 15 wt%. Nevertheless, the content
of these impurities might be lowered in sorbent by acid treatment. AC BA11 delivered by Carbon, Poland contains 11 wt%
of inorganic impurities. Acid treatment (HCl, HNO3 and HF) was performed to remove ash and its result on CO2 sorption
capacity was measured for each sample. Samples were characterized in terms of texture (BET) and chemical composition (XRF,
XRD and XPS). The highest enhancement of 44% CO2 sorption capacity was achieved for activated carbon after hydrofluoric
acid treatment.
