Desulfurizer: commonly used biogas desulfurizers include Calcium oxide, sodium hydroxide, Calcium hydroxide, ammonia, etc. These desulfurizers can react chemically with hydrogen sulfide, converting it into non-toxic or low toxic compounds, and removing hydrogen sulfide from biogas.
Catalysts: In certain special circumstances, catalysts are required to promote reaction rate and improve desulfurization efficiency during the biogas desulfurization process. Common catalysts include metal oxide catalysts, oxygen rich catalysts, etc.
Solvent: The solvents used to absorb and remove hydrogen sulfide in biogas usually include organic solvents such as Ethanolamine and methanolamine. These solvents have good absorption performance and can effectively react with hydrogen sulfide to achieve desulfurization purposes.
Auxiliary materials: In biogas desulfurization equipment, it may also be necessary to use some auxiliary materials, such as fillers, filtering materials, adsorbents, etc. These materials are used to improve the desulfurization efficiency of equipment, separate impurities, or fix desulfurization agents.
It should be noted that the selection of suitable raw materials for biogas desulfurization equipment is closely related to specific process conditions, hydrogen sulfide concentration, desulfurization efficiency requirements, and other factors. Therefore, in the actual production process, technical scheme design and raw material selection should be based on different situations.
