Global Dry-Process Biogas Desulfurizer Market Strategic Research Report

Scope of the Report

The global Dry-Process Biogas Desulfurizer market size is predicted to grow from US$ 163 million in 2025 to US$ 216 million in 2032; it is expected to grow at a CAGR of 4.2% from 2026 to 2032.

Dry-process biogas desulfurization agents are solid purification materials used to remove hydrogen sulfide from biogas. Typically utilizing iron oxide, impregnated activated carbon, or composite metal oxides as their primary active ingredients, they convert and immobilize hydrogen sulfide through adsorption, chemical reaction, or catalytic oxidation. These products are generally loaded into fixed-bed desulfurization towers; the systems feature simple equipment structures, generate no liquid waste during operation, and are easy to maintain. They are primarily used for gas purification prior to biogas power generation, biomethane upgrading, and combustion applications.

The upstream segment of the industry chain primarily involves active materials—such as iron oxide, activated carbon, and composite metal oxides—and carrier materials like diatomaceous earth, clay, sawdust, and plant fibers; some products also incorporate alkaline impregnating agents, binders, and molding aids. Midstream enterprises formulate the products based on factors such as biogas sulfur content, humidity, and outlet specifications, manufacturing granular or pelletized desulfurization agents through processes including mixing, impregnation, molding, and drying. Downstream applications primarily serve livestock farms, wastewater treatment plants, landfills, and industrial organic wastewater treatment projects, facilitating hydrogen sulfide removal for biogas power generation, biomethane upgrading, and combustion.

In 2025, global sales volume is approximately 150,000 tons, with an average selling price of around US$950–1,100 per ton and gross margins for major manufacturers ranging from 20% to 30%. Industry growth is primarily driven by the expansion of biogas upgrading and biomethane projects, as well as the adoption of desulfurization materials with higher sulfur-loading capacities.
