About Us

RST was founded in 1982 as Ejokras BV and rebranded in 2017. With more than four decades of specialist experience, we provide high‑quality consultancy and supervision for catalyst operations in refineries worldwide.

Ejokras BV was represented for many years by Habbo Edens, who brings over 45 years of global experience in catalyst handling, both operationally and in senior management roles. In 2015, Jelle Kramers, former Director at Mourik International, joined the company. Together, they combine deep industry knowledge into RST — offering reliable expertise in reactor inspection, catalyst change‑out supervision, and reactor maintenance.

At RST, we work closely with refineries, catalyst suppliers, sub‑contractors, and regeneration partners to deliver safe, efficient, and high‑quality solutions throughout the entire catalyst change‑out process — from planning to execution. After each project, we provide clear, comprehensive reporting supported by accurate visual documentation.

With tightening emission standards and increasing demand for precious metals, optimal catalyst performance and effective regeneration are becoming more critical than ever. RST maintains strong industry relationships and continuously embraces technical innovation to deliver true value during refinery turnarounds and reactor maintenance.

Our operational staff is selected for their experience, technical know‑how, safety awareness, and commitment to quality.

Faster, safer catalyst change‑out — that’s RST.
