Coadsorption of gaseous xylene, ethyl acetate and water onto porous biomass carbon foam pellets derived from liquefied Vallisneria natans waste

Abstract: BACKGROUND Only a few studies have focused on the purification of waste gas containing a mixture of volatile organic compounds (VOCs) with engineered biochar. The adsorption behaviors of gaseous xylene and ethyl acetate (EA) individually and in binary mixture onto porous biomass carbon foam pellets (BCFPs) were studied by static headspace gas chromatography. RESULTS The removal efficiency nearly reached 100% for 17.32 mg L−1 xylene and 18.02 mg L−1 EA within 120 min at a BCFP dosage of 0.2 g L−1, a temperature… Show more

“…Lightweight shaped carbon foam pellets derived from eucalyptus sawdust were prepared successfully following our previous study [ 9 , 29 ]. Briefly, 20 g of eucalyptus sawdust, 60 g of phenol, and 1.96 mL of H 2 SO 4 were mixed in a 250 mL three-necked flask, and liquefaction reaction was initiated at 150 °C under vigorous stirring for 2 h. After cooling, liquefied product was washed with methanol and filtrated.…”

“…For example, the combination of activated carbon and ion exchange resins improved the adsorption of pesticides since the pore blockage was alleviated by the anion exchange effect. [ 266 ] The adsorption behavior of organic compounds on carbon based materials generally follows the mechanisms as below [ 97 ] ( Figure ): π‐π interactions, [ 11,267 ] hydrophobic effects, [ 175 ] hydrogen bonds, [ 267,268 ] electrostatic interactions, [ 269,270 ] pore‐filling mechanism.

“…Therefore, it is very necessary to develop new materials and methods to effectively reduce or remove these organic pollutants. [ 7 ] Studies have been conducted to develop highly efficient adsorption processes, including adsorption, [ 8–12 ] coagulation, [ 13,14 ] precipitation, [ 13,15 ] membrane separation, [ 16–18 ] chemical oxidation, [ 19–21 ] photocatalytic degradation, [ 22,23 ] and electrocatalysis. [ 24 ] Among various methods, adsorption method has drawn increasing attentions due to the wide range of applications, facile operation, high efficiency and low cost.…”

“…The xylene [20] was heated in nitrogen atmosphere at 145℃; 1/2 amount of cross-linking agent [21] (allyl methacrylate) and acrylate monomer (the mixture of hydroxyethyl acrylate and iso-octyl acrylate with a mass ratio of 1:3) was added, and then 1/2 amount of initiator (ammonium persulfate aqueous solution) was dropped for 1.5 h.…”
