By Types, the market is organized into three core categories, each with distinct sub‑technologies that influence overall market valuation. Chemical agents such as amine‑based solvents, caustic solutions, and proprietary organics dominate the landscape, offering high reactivity for sulfur capture and accounting for roughly 55 % of market value due to their widespread use in large‑scale plants. Physical adsorbents—including activated carbon, zeolites, and metal‑organic frameworks—provide surface‑based removal mechanisms, contributing about 30 % of revenue, particularly in niche applications where regeneration and low‑temperature operation are critical. Biological agents, exemplified by enzyme‑mediated desulfurization and microbial treatment systems, represent an emerging segment valued at approximately 15 %, driven by sustainability mandates and the need for low‑chemical‑footprint solutions. The relative weight of each type reflects both technological maturity and regulatory pressure, shaping investment and R&D focus within the broader Desulfurization And Decarbonization Agent market.
