Abstract: Growing demand for renewables and sustainable energy production contributes to a growing interest in producing high quality biomethane from biogas. Despite having methane (CH 4 ) as its main component, biogas may also present other noncombustible substances in its composition, i.e., carbon dioxide (CO 2 ), nitrogen (N 2 ) and hydrogen sulfide (H 2 S). Contaminant gases, such as CO 2 and H 2 S, are impurities known for being the main causes for the decrease of biogas calorific value and corrosion, wear of pipes, and engines, among others. Thus, it is necessary to remove these compounds from the biogas before it can be used in applications such as electricity production, thermal purposes, and replacement of conventional fossil fuels in vehicles, as well as injection into natural gas distribution networks. In this context, the present work aimed to present a systematic review of the literature using the multicriteria Methodi Ordinatio methodology and to describe processes and materials for H 2 S removal. The discussion indicated new materials used, as well as the advantages and disadvantages observed and the limitations in industrial implementation.
