In order to improve the portability of basic absorbents monoethanolamine (MEA) and glycine (Gly), both were supported on microporous activated carbon (AC). Chemical modification by alkali-metal ion exchange (of Li, Na, K) was carried out on Gly-based

A catalyst of Ag with alumina has been widely used for the decomposition of odorous ammonia. In order to meet cost effectiveness, copper was added with five different doping ratios of Ag/Cu in this work, and NH3 decomposition was examined at 150–40

In an effort to enhance the selective capture of CO2, heat treatment of 1 M KOH-doped activated carbon (AC) under inert (N2) and reducing (NH3) atmospheres was used. With N2 only, modified adsorbent became unstable to air upon retrieval. Therefore, s

This work attempted to use H2O2 as an oxidant for the incorporation of surface oxygen functionalities (SOFs) on activated carbon in the preparation of a CO2 adsorbent. Experimental results showed that oxidation at lowered temperature improved both st

The present study has evaluated the CO 2 adsorption amount of activated carbon pellets (AC). Coconut shellbased test AC were modi Þ ed with surface impregnation of glycine, glycine metal salts and monoethanolamine forlow level CO 2 (3000ppm) adsorpt

In order to enhance the selectivity of activated carbon (AC) toward CO2, surface modification was carried out in a two-step approach viz. pre-oxidation and amination. First, the most suitable oxidation was determined by using O3 and H2O2 with or with
