STRATCO® Alkylation Technology

STRATCO®: The World-Leading Sulfuric Acid Alkylation Licensor

With over 80 years’ experience, STRATCO® technology helps refiners safely produce cleaner-burning gasoline with high octane, low RVP, low sulfur, and zero olefins. Our comprehensive products and services deliver lifelong support.

Originally developed in the late 1930s, and then licensed to refiners on a global scale, STRATCO® alkylation technology is based on decades of experience. We license sulfuric acid alkylation technology to oil refiners and offer equipment fabrication and lifelong support for our customized products and services. Our technology experts can work with you to assess and determine the right solution for your refinery. We support you every step of the way, from proposal, technology evaluation, and design through equipment fabrication, startup, and training. Our support continues in lifelong reactor component replacements, repairs, process-critical equipment, improvement studies, and operator training programs.

STRATCO® Alkylation Technology Licensing

Licensed and designed by DuPont, STRATCO® alkylation technology continues to be the preferred refinery technology for grassroots, revamp and expansion projects throughout the world.
