Capabilities dual chemical mixture (DCM) adsorbents through metal anchoring in H2S captured

— A laboratory scale investigation on H2S adsorption performances is carried out, utilizing thesynthesis and characterization of modified commercial activated carbon (CAC) through wt. ratios of dualchemical mixture (DCM). The synthesis of DCM adsorbents prepared with anchoring two types of metalmaterial on the CAC surfaces by varied the wt. ratio at 1:1 and 2:1 based on recommended wt.% of znac2 inprevious study. All the prepared adsorbents undergo SEM EDX, BET, BJH N2 adsorption analysis forfurther morphology study. At the same time, the adsorbents also run for H2S adsorption performancethrough 0.2 L adsorber column at ambient temperature with flowrate and pressure fixed as 5.5 L/min and 1.0bar. Then, the H2S adsorption capacity calculated based on the breakthrough time of H2S for eachadsorbent. The modified adsorbents show longer H2S loading on the adsorbents surface where reduce theadsorbents changing period. Besides, these performances related towards surface morphology changing thatacquire better H2S captured. Finally, the H2S adsorption capacities is improve up to 43% compared to rawCAC, which the proposed method completely suppresses commercial CAC.
