  Abstract:  Since the micro structure of the adsorbant has an important influence upon its reactivity, this paper presents the - in situ - generation of calcium oxide process from limestone. The calcium oxide obtained by calcination of limestone at temperatures of 973-1273 K and p=0,3404 bar was characterised by BET surface area, porosity and pore size distribution. The obtained surface areas are in the range between 18,9107 - 55,1966 m2/g and a porosity in the range of mesopores as a function of the particles size and the decomposition temperatures.
