However, higher % of nano-silica coating increases resistance to CO2diffusion which increases the activation energy. The corresponding reaction model for decomposition was predicted by M谩lek's method. Experimental data was in good agreement with the theoretical model proposed by est谩k Breggren (SB...

Calcium oxide (CaO) is recognized as an efficient carbon dioxide (CO2) adsorbent and separation of CO2 from gas stream using CaO based adsorbent is widely applied in gas purification process especially at high temperature reaction. CaO is normally been produced via thermal decomposition of calcium ...
Because of its commercial significance any information concerning the nature of the CaO phase is important. I report here on the ultrastructure and crystallography of the reaction products obtained by the in situ and in vacuo thermal decomposition of calcite in the transmission electron microscope (...
It has been estimated that the available accessible reserves of clean phosphate rock may get depleted within the next 50 years2. Currently, there is a growing interest in the technique of removal and recovery of TAN and PT through struvite precipitation by the following reaction3–6. Mg 2+ +...
