Global COS Hydrolysis Catalyst Market Strategic Research Report

Scope of the Report

The global COS Hydrolysis Catalyst market size is predicted to grow from US$ 123 million in 2025 to US$ 173 million in 2032; it is expected to grow at a CAGR of 5.0% from 2026 to 2032.

COS hydrolysis catalysts are industrial catalysts loaded into fixed-bed reactors to catalyze the reaction between carbonyl sulfide (COS) and water vapor, producing hydrogen sulfide (H₂S) and carbon dioxide (CO₂); the primary reaction is COS + H₂O → H₂S + CO₂. Their function is to convert COS—which is difficult to remove to deep levels using conventional amine solutions or solid desulfurizers—into H₂S, a compound that is easier to handle. This process reduces the total sulfur content of the feed gas and protects downstream catalysts used in ammonia synthesis, methanol production, hydrogen generation, and methanation.

Upstream raw materials primarily include support materials such as pseudoboehmite, activated alumina, and titanium dioxide, as well as promoters like potassium carbonate, potassium hydroxide, chromium salts, vanadium salts, and other metal oxides; binders, pore-forming agents, and shaping aids are also utilized. Downstream applications mainly involve purification units for coal-gasification syngas, natural gas, steel industry off-gases, refinery gases, and petrochemical feedstocks; these catalysts are typically used in conjunction with zinc oxide desulfurizers, iron-based desulfurizers, amine-based acid gas removal systems, or Claus sulfur recovery units.

Global sales volume is projected to reach approximately 30,000 metric tons in 2025, with a comprehensive average market price of around $4,000 per ton and gross profit margins for major manufacturers ranging from 25% to 38%.
