Zeolyst International is a global leader in specialty zeolite powders, catalysts, and adsorbents. Founded in 1988, the company develops, manufactures, and supplies zeolite-based advanced materials for applications in refining, petrochemicals, chemicals, sustainable fuels, emission control, and advanced plastics recycling.
It maintains state-of-the-art manufacturing facilities in Kansas City, Kansas, USA, and Delfzijl, The Netherlands, along with an extrusion plant in Ghent, Belgium. Research, development, and scale-up occur at Technip Energies R&D centers near Philadelphia, Pennsylvania, and Shell Technology Centers in the Netherlands. All facilities are ISO 9001 certified.
Zeolyst International operates as a 50/50 joint venture partnership. Originally formed between predecessors of Ecovyst and Shell Catalysts & Technologies, the structure evolved in 2026 when Technip Energies acquired Ecovyst’s Advanced Materials & Catalysts division, now positioning Zeolyst under Technip while retaining the Shell partnership.
The product portfolio includes standard and custom zeolite powders, hydrocracking catalysts, specialty catalysts for aromatics (trans-alkylation, paraffin isomerization, ethylbenzene processing), and the Opal™ suite of branded materials for renewable diesel, sustainable aviation fuel, and circular economy solutions. The company serves global customers with custom catalyst development, technical support, and optimization services.
Headquartered in Conshohocken, Pennsylvania, USA, Zeolyst is recognized as a trusted technology partner in the chemical and refining industries, emphasizing material science expertise, quality, and sustainability-focused innovations.
