Catalyst handling services

Charging and discharging reactors is a critical job that demands the highest levels of safety and efficiency, making catalyst handling very specialised work. Mourik is recognised as the leading catalyst handling service provider and one of the few companies in the world that have mastered this task.



Increasing pressure on the petrochemical industry means our customers require the most reliable and cost effective reactors, with minimum downtime and maximum runtime and performance. Catalyst handling is a critical activity to help the industry gain maximum reactor performance.

Our techniques and quality control procedures result in minimum breakage and attrition of catalyst during handling, whilst ensuring that material is loaded precisely to the required specification.
