A POSSIBLE WAY TO STORAGE CARBON DIOXIDE ON MECHANICALLY ACTIVATED OLIVINE (Mg,Fe)_2SiO_4

摘要

This paper deals with mechanical carbonation of olivine by dry and wet modes. Mechanical activation and carbonation of the olivine samples have been performed using a planetary mill, Pulverisette 6 (Fritsch, Germany). A series of experiments were produced where the activated products were exposed to carbon dioxide during activation in presence of water and by dry mode of milling. To identify mechanically induced changes in surface of the mineral, specific surface area measurements have been used. To identify carbon dioxide sequestration, infrared spectroscopy and determination of total carbon have been used. Infrared spectroscopy seemed to be a suitable method for characterization of CO_2 absorption on mechanically modified olivine.
