“…The average sorption capacity was 2.8 kg H 2 S$t À1 dry FBA, which is similar to the value reported by Ducom et al (2009) [17] (3.5 kg H 2 S$t À1 dry FBA). Even though the H 2 S uptake was maximum during the first hour of the assay, the FBA showed H 2 S removal efficiencies in the range of 70e100% during the whole experimentation period.…”

“…Rendek et al [16] also determined how BA finest fractions (0e4 mm) have a sorption capacity higher than unsieved BA due to the larger reactive surface area and greater calcium oxide content. Finally, Ducom et al [17] focused in the capacity of BA to sequestrate sulfur compounds from landfill gas, reporting a sorption capacity of 3 kg H 2 S per ton of dry BA. According to these publications, there is evidence that BA can be used for anaerobic digestion biogas upgrading at the same time as BA stabilization is accelerated.…”

Biogas upgrading using MSWI bottom ash: An integrated municipal solid waste management

a b s t r a c tBiogas upgrading using bottom ash from the incineration of municipal solid waste (MSW) is especially interesting for integrated treatment facilities as it would allow closing a complete loop in MSW management. The aim of this research was to assess the interaction between bottom ash (BA) and biogas from anaerobic digestion with the outlook of upgrading in terms of CO 2 and H 2 S removal, with particle size and bottom ash aging as the main variables. The finest fraction of fresh bottom ash (FBA) presented the best performance, with a sorption capacity of 30e50 kg CO 2 $t À1 dry FBA. The sorption capacity of weathered bottom ash (WBA) was lower than the recorded for the fresh material. From the results obtained it can be stated that the CO 2 absorption capacity of bottom ash mainly relies in the finest fraction because of its larger surface area and higher CaO content. In what respect to H 2 S sorption capacity, WBA presented a better performance, with values ranging 3.1e5.2 kg H 2 S•t À1 dry WBA. In addition to the energetic enhancement, the proposed technology also allows an immediate stabilization and reuse of bottom ash as the leaching of heavy metals and metalloids remained under regulatory limits.

“…H 2 S also occurs in volcanic and natural gases. Several processes are available for the treatment of hydrogen sulfide, including absorption [1][2][3][4][5], adsorption [6][7][8][9][10][11], and membrane separation [12][13][14][15][16]. These methods generally entail high energy, chemical and disposal costs.…”

AbstractThe objective of this study was to investigate the removal of hydrogen sulfide (H 2 S) present in air using cellular concrete waste as the packing material. Air filtration was performed under biotic and abiotic conditions. Experiments were carried out in a laboratory-scale PVC column (internal diameter of 300 mm) filled with a volume of 70 L of cellular concrete (1 m height).The polluted air flow was generated at 4 m 3 h -1 corresponding to an Empty Bed Residence Time (EBRT) of 63 s. In dry conditions without biomass (abiotic conditions), cellular concrete can be an effective medium for the treatment of H 2 S in air. For an H 2 S concentration of 100 ppmv, the removal efficiency was around 70 % (Elimination Capacity (EC) of 5.6 g m -3 h -1 ). This finding can be explained by the physicochemical reactions that can take place between H 2 S and the cellular concrete components (mainly CaO, CaCO 3 and Fe 2 O 3 ).However, interactions between cellular concrete and H 2 S are not yet fully understood. Used as a packing material for H 2 S biofiltration (biotic conditions), cellular concrete waste efficiently 2 treated (Removal Efficiency = 100 %) high concentrations of H 2 S (up to 133 ppmv corresponding to an EC of up to 10.5 g m -3 h -1 ). Physicochemical and biological mechanisms explaining H 2 S removal seem to occur simultaneously in the biofilter. At an EBRT of 63 s, the maximal elimination capacity (EC max ) was 17.8 g m -3 h -1 . A packed bed of cellular concrete also presents a satisfactory mechanical behavior with low pressure drops.

The chemical absorption process for carbon dioxide (CO2) capture is a promising method to reduce greenhouse gas emissions in the energy industry. Worldwide applications of the CO2 chemical absorption process will consume plenty of chemical absorbents and have hazardous impacts on the environment. The development of renewable absorbents from biomass can not only fill the gap of absorbent production, but also provide a novel green approach to recycle the used absorbents into nature without additional pollution. In this review, we summarized several renewable absorbents available from biomass such as biomass ash slurries, alkanolamines, aqueous ammonia, and amino acid salts. The preparations, CO2 absorption capacities, advanced treatments, and applications of the renewable absorbents were also reviewed. Moreover, the advantages and challenges in the preparation of the renewable absorbents were discussed, as well as their CO2 absorption performance improvement. Finally, future research avenues into degradation and utilization of renewable absorbents in nature were suggested. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
