Key Players
Competitive Landscape
Competition splits between licensors that sell adsorbents with process designs and service, specialist molecular sieve and silica producers, and activated carbon and clay suppliers. Honeywell UOP offers molecular sieve and activated alumina portfolios for air separation and MOLSIV grades for syngas and PSA hydrogen purification. Arkema supplies Siliporite zeolites and alumina for refining, hydrogen and gas dehydration duties.
Recent activity points to portfolio reshaping and capacity aimed at specific duties. BASF has scaled Durasorb LNG MAX at Cheniere's Corpus Christi site. Calgon Carbon is adding reactivation capacity for drinking water carbon. Zeochem completed the SiliCycle acquisition in July 2025 after integrating Sorbead India and Swambe Chemicals in 2024. Technip Energies now owns Ecovyst's former silica and zeolite business.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| September 2026: BASF reported Durasorb LNG MAX in operation at Corpus Christi LNG | LNG pretreatment needs | Single-unit adsorption designs | Retrofits of existing dehydration units |
| February 2026: Calgon Carbon announced 12,300 t/yr reactivation capacity in Ohio | PFAS drinking water limits | Reactivation over virgin carbon | Long-term utility supply contracts |
| February 2026: Axens completed full ownership of Eurecat | Refinery catalyst and media change-outs | Service-led offerings | Bundled media and services for refiners |
| January 2026: Technip Energies completed purchase of Ecovyst's AM&C business | Refining and sustainable fuels | Engineering firms owning materials | Integrated technology and materials packages |

BASF and Honeywell UOP lean on process expertise and modelling, Calgon Carbon competes on reactivation and utility contracts, and specialist producers such as Zeochem and Luoyang Jalon compete on molecular sieve grades and cost.
Who leads the adsorbents market?
Supplier strength in the adsorbents market differs by type. BASF and Honeywell UOP document gas and air separation adsorbents, Calgon Carbon leads the evidence on drinking water carbon, and Clariant on refinery clays.
Which companies show the deepest recent product activity?
Published product data is available from BASF (Durasorb gas treatment adsorbents), Arkema (Siliporite molecular sieves), W. R. Grace & Co. (SYLOBEAD molecular sieves and hydrocarbon-grade silica gel), Honeywell UOP (MOLSIV molecular sieves and activated alumina), Calgon Carbon (FILTRASORB granular activated carbon), Clariant (TONSIL clays and desiccants) and KNT Group (3A, 4A, 5A and 13X molecular sieves and activated alumina).
What should buyers evaluate before approving a supplier?
Refinery, gas and utility buyers should test adsorption capacity at process conditions specific to the site, then check crush strength and attrition, regeneration stability over cycles, co-adsorption behaviour, contaminant breakthrough data, spent-media take-back or reactivation options, and the supplier's modelling and start-up support.
How is competition expected to change through 2036?
Competition is expected to centre on guaranteed bed life, regeneration energy and service. Ownership changes in 2026 put silica and zeolite assets with an engineering company and expanded Axens' service base, which may strengthen bundled offers to refiners.
