Application Sectors and Industries of Zinc Oxide Catalysts
Oil & Gas Desulfurization
Removes H₂S, COS, and organic sulfur from natural gas, syngas, and hydrocarbon feedstocks. Protects downstream catalysts in refineries and petrochemical plants.
Hydrogen & Ammonia Production
Purifies feed gases in hydrogen and ammonia synthesis, reducing sulfur to <0.1 ppm to prevent catalyst poisoning.
Methanol & Alcohol Synthesis
Ensures sulfur-free feedstocks for methanol reactors, enhancing catalyst longevity and product purity.
Environmental Remediation
Captures sulfur emissions from industrial exhausts, reducing air pollution and complying with environmental regulations.
Rubber & Elastomer Manufacturing
Acts as a vulcanization accelerator and UV stabilizer in tire production, improving durability and weather resistance.
Pharmaceuticals & Cosmetics
Used in calamine lotions, ointments, and sunscreen formulations for its antiseptic and UV-blocking properties.
Ceramics & Glass Production
Enhances thermal resistance and opacity in glazes, ceramics, and specialty glass.
Electronics & Semiconductors
Serves as a piezoelectric material in sensors, transistors, and LED devices due to its semiconducting properties.
Agriculture
Neutralizes acidic soils and acts as a micronutrient in fertilizers, promoting plant growth.
Paints & Coatings
Provides UV resistance and anti-corrosive properties in industrial coatings and marine paints.
