Hydrogen sulfide (H 2 S) is a flammable, corrosive and lethal gas even at low concentrations
(ppm levels). Hence, the capture and removal of H 2 S from various emitting sources (such …

Biogas is a biorenewable energy resource that has the potential to serve as a possible
replacement for fossil fuels, especially natural gas and as a hydrogen carrier. However, raw …

Abstract Hydrogen sulfide (H 2 S), as a major air pollutant, poses a serious threat to peoples
health, especially in confined spaces. In this study, a porous carbon filter was developed by …

H 2 S has become a significant environmental problem because of its high toxicity,
corrosiveness, and low olfactory threshold. Therefore, the high-performance removal of H 2 …

Among the others, CO 2 and H 2 S are the major impurities present in biogas which typically
hampers its direct application as biofuel. Therefore, an upgradation for the purity of biogas is …

Two activated carbons (AC) resulting from CO 2 activation of Maize Cob Waste (MCW) were
investigated as adsorbent materials for biogas upgrading to bio-methane applying a …

Caffeine in water resources has been reported, indicating the need for alternative
treatments. Activated carbons (ACs) are efficient adsorbents; however, they present issues …

KOH-modified biochars derived from by-products of microalgae pyrolysis were prepared to
adsorb gaseous H 2 S. Influences of various parameters (eg, mass ratio between KOH and …

Biogas, eg, biomethane, is produced by fermentation of organic matter and can be used as
an alternative fuel or as a raw material for the production of hydrogen and syngas. However …

Contaminants of emerging concern (CECs) are a new class of pollutants that may pose
environmental and human risks. Such contaminants are prevalent in the environment as …
