Marine Fuel Sulfur Rules Drive Higher-Activity Formulations
Refiners producing compliant marine bunker fuel under International Maritime Organization sulfur limits are increasingly specifying higher-activity hydrotreating catalysts capable of processing heavier residue streams into low-sulfur marine fuel blends. Albemarle Corporation and Criterion Catalysts and Technologies have both expanded high-activity catalyst production capacity over the past two years to serve this growing marine fuel compliance demand. At least a dozen major refiners have upgraded catalyst specifications for marine fuel compliance since 2023, and suppliers report this shift is meaningfully expanding addressable high-value demand across previously standard-grade accounts. with several additional refiners reportedly evaluating similar upgrades within the next two years.
