KATALCO™ 27-2
High temperature ammonia cracking catalysts
- A nickel-based ammonia cracking catalyst that has been supplied to ammonia cracking applications for over 50 years. It is a highly active catalyst that typically operates in the range 650 - 950°C, giving high hydrogen yield due to the low residual ammonia levels at this temperature range.
KATALCO™ 27-200MQ
- A nickel-based ammonia cracking catalyst that leverages the proven chemistry of KATALCO 27-2 and applies the benefits of improved heat transfer of Johnson Matthey’s QUADRALOBE™ shape to the ammonia cracking reaction. This high geometric surface area catalyst typically operates in the range 650 – 950°C and benefits from enhanced heat transfer performance to maximise process efficiency.
KATALCO™ 27-612
Low temperature ammonia cracking catalysts
- A pgm-based ammonia cracking catalyst, developed for low temperature ammonia cracking. This catalyst typically operates in the range 400 – 500°C, substantially extending the available operating range for ammonia cracking applications. The overall economics of a low temperature application will be a balance between the savings associated with lower temperature operation and the increased catalyst costs for pgm-based catalysts.
World-class performance
Ammonia cracking is the process by which ammonia is decomposed towards hydrogen and nitrogen over a catalyst (based on base or pgm metals). It's typically used in applications where hydrogen is needed as either an energy source or fuel for downstream manufacturing processes.
Johnson Matthey supplies ammonia cracking catalysts, suitable for use over a wide range of temperatures. Both types of catalyst can be manufactured in a range of sizes and give dependable, long and active lifetimes. Our experience is based on more than 50 years of operating experience in cracking applications.
Along with dedicated technical service, we offer licensed technology to support clean ammonia cracking.
