Regeneration of catalyst clay soils (Tonsil CO 610 G) by supercritical carbon dioxide
E-mail:
Extraction of deactivatived materials from contaminated clay soils (Tonsil CO 610 G) by supercritical carbon dioxide was investigated. Effect of different conditions including extraction temperature (308.15-338.15 K) and pressure (100-330 bar) (thermodynamic conditions), flow rate (4.2-42.6 cc/min), and static time (45-85 min) were investigated to find the optimum conditions for extraction of deactivatived materials. Based on the different experiments, optimum conditions for flow rate (4.2 cc/min), static time (85 min) and extraction pressure and temperature (330 bar and 313.15 K) were obtained. In addition, the GC-MS analysis and Bromine index (BI) analysis were revealing that the clay soil is activated and could be used as catalyst again.
