COOL-MTJ
Countering Oligomerization Inhibition in Methanol to Jet
Background
The COOL-MTJ project supports our ambition to establish a cost-efficient process to produce sustainable aviation fuel (SAF) through three integrated steps: methanol conversion to olefins (MTO), olefin oligomerization (OLI) and hydrogenation.
In the project we want to obtain a molecular understanding on the nature, and quantity, of certain critical side products, and how these influence the catalyst performance in the methanol-to-jet (MTJ) process. This will help identify the best design for a future MTJ plant, leading to the lowest cost of SAF.
Objectives
- To produce representative olefinic samples in a pilot plant for analytical investigation.
- To develop analytical methods tailored for identifying ppm levels of impurities in olefinic hydrocarbon streams and apply these methods.
- To establish a bench-scale test setup for experimental studying inhibition effects of the impurities under different conditions.
- To improve the MTJ process layout based on learnings obtained.
Expected results/impact
The COOL-MTJ project provides chemical understanding on how to integrate two core steps of the MTJ process and best tune their operational parameters to achieve high efficiency and SAF yields.
- Improved analytical capabilities to understand subtle differences in the product compositions at different conditions.
- Improved understanding on chemical species present and their interaction with the catalysts.
- Better integration of two core steps in the MTJ process and improved process design.
- Improved MTJ process leading to lower cost SAF.
