Solid Catalyst – Alkylation

Idaho National Laboratory

Contact INL About This Technology

Technology Marketing Summary

This is a method used to reactivate solid/liquid catalysts used in INL’s super critical process to produce alkylates. The method brings the catalyst into contact with the designated fluid that serves as the reactivating agent and has the density to dissolve the impurities. The process reactivates the catalyst by exposing it to a series of agents to dissolve the fouling agents. Once the catalyst has been processed with the fluid-reactivating agents, it is then separated so that it may be used again. The fluid reactivating agent is then be reused in subsequent reactions.


This technology also includes a secondary method for reactivating where a solid alkylation catalyst can be performed inside or outside a reactor that holds the catalyst. The reactivation can be done whether the catalyst is partially or completely deactivated. A fluid-reactivating agent is used to dissolve with fouling agents so that the reaction products can be disposed. Near-critical, critical, and supercritical pressures and temperatures are used in the process. This process is critical to the reactivation of a solid catalyst that is either partially or completely deactivated.


- Reactivates a solid catalyst that is either partially or completely deactivated, and

- Reuses the reactivating fluid by separating it from the process.
