Carbon Dioxide Adsorption on Solvothermolyzed Nano-Dolomite.

In this work activated dolomite adsorption was investigated for removal ofacidic gaseous
pollutants which in this case is CarbonDioxide. Charring was found to be an effective method
for the activation of dolomite based on the literature review and some previous research
conducted by chemist. This thermal processing resulted in partial decomposition, yielding a
calcite and magnesium oxide structure. Adsorbentswere produced over a range of char
temperatures (500, 700 and 900 °C) and char times (1-8 h). The surface properties and the
adsorption capability of rawandthermally treated dolomite sorbentswere investigatedusing
SEM, XRD and BET. The sorbate individually investigated was C02.Using the TPDRO the
activated dolomite was tested to produce result as a potentially cost effective material for acidic
gases adsorption.
From the results obtained, the results were not like what had been expected. The method
used was found not preferable for the project. To continue this research it is recommended to use
other options or methods for adsorption experiment.
