Activated carbons (M4P0, M4P2, and M5P2) used in
\r\nthis research were produced from palm shell and polyetherether
\r\nketone (PEEK) via carbonization, impregnation and microwave
\r\nactivation. The adsorption\/desorption process was carried out using
\r\nstatic volumetric adsorption. Regeneration is important in the overall
\r\neconomy of the process and waste minimization. This work focuses
\r\non the thermal regeneration of the CO2 exhausted microwave
\r\nactivated carbons. The regeneration strategy adopted was thermal
\r\nwith nitrogen purge desorption with N2 feed flow rate of 20 ml\/min
\r\nfor 1 h at atmospheric pressure followed by drying at 150oC.Seven
\r\nsuccessive adsorption\/regeneration processes were carried out on the
\r\nmaterial. It was found that after seven adsorption regeneration cycles;
\r\nthe regeneration efficiency (RE) for CO2 activated carbon from palm
\r\nshell only (M4P0) was more than 90% while that of hybrid palm
\r\nshell-PEEK (M4P2, M5P2) was above 95%. The cyclic adsorption
\r\nand regeneration shows the stability of the adsorbent materials.<\/p>\r\n","references":"[1] C.S. Lee, Y.L. Ong, M.K.
