Biogas is one of the most attractive renewable resources because of its ability to convert waste into energy. Biogas is composed mainly of CH4, CO2, and some trace gases such as hydrogen sulphide (H2S) which is a very toxic, deadly and corrosive gas. Therefore, raw biogas needs to be cleaned of hydrogen sulphide before it can be used in many applications. The overall objective of this work was to investigate the removal efficiency of hydrogen sulphide (H2S) by activated carbon based on borassus aethiopum. Borassus aethiopum, also known as roast tree, is an abundant agricultural resource in the rural areas of western, central and northern Côte d'Ivoire. Physico-chemical parameters such as iodine value, ash content, pH at zero load point, tapped density were determined to characterize the synthesized activated carbon. The tests for the elimination of H2S by adsorption on activated carbons were carried out at the BRIN FOUNDATION poultry farm, located in the village of YAOKOKOROKO, sub-prefecture of TABAGNE in the GONTOUGO region. This farm has a methaniser with a capacity of 15 m 3 for the treatment of the chicken Removal of … EHOUMAN Ahissan Donatien et al.

“…The rapid growth in the development and characterization of H 2 S adsorbents (~2000 published works in the past 15 years, >1500 in the past 10 years, and >1000 in the past 5 years) has resulted in a number of reviews published over the past few years: adsorption [233,235,236,[240][241][242][243], zeolites [244], metal oxides [245], and MOFs [246][247][248]. In the interest of not repeating the same information that can be found in the aforementioned sources, this section will review the most recent developments in the field.…”

“…Although there have been a number of qualitative review studies [3][4][5][6][7] devoted to the theoretical and experimental separation of H 2 S on the different types of adsorbents, such as zeolites, activated carbon, MOFs, oxides, and so on, there is still a lack of consensus regarding the best method. This article focuses on the experimental removal of H 2 S from natural gas, biogas, air, and refinery gases in the past decade utilizing zeolites, zeolite-based adsorbents, and waste-based adsorbents.…”

Natural gas, biogas, and refinery gas all include H2S, which has adverse effects not only on the environment and human health but also on the equipment and catalysts that are employed in the relevant processes. H2S is removed from the aforementioned gases using a variety of techniques in order to fulfill the necessary sales criteria and for reasons of safety. The adsorption method stands out among various other approaches due to its straightforward operation, high level of efficiency, and low overall cost. This technique makes use of a variety of adsorbents, such as metal-organic frameworks (MOFs), activated carbon, and zeolites. The use of zeolite-based adsorbents is by far the most common of these various types. This is due to the specific properties of zeolite-based adsorbents, which include a high adsorption capacity, the ability to be regenerated, a high temperature stability, a diversity of types, the possibility of modification, high efficiency, and low cost. In addition, research is being done on adsorbents that are made from inexpensive raw materials in order to remove H2S. This article focuses on zeolites, zeolite modifications, and wastes as an adsorbent for the removal of H2S, all of which have been investigated fruitfully in recent years, as well as the promising applications of zeolites.
