Performance Evaluation of Ammonia Synthesis and Decomposition Catalyst

ーContinuous Monitoring of Ammonia (NH3) Concentrationー 

Ammonia is attracting attention as a next-generation clean fuel, but its effective use requires optimizing its synthesis and decomposition processes. A key factor that greatly impacts this efficiency is the catalyst used for ammonia synthesis and decomposition.

To evaluate catalyst performance, real-time analysis of ammonia concentration is essential. However, traditional methods have been limited to intermittent techniques, such as gas chromatography quantification or capturing ammonia with hazardous sulfuric acid and measuring its concentration through conductivity changes.

Do you have any challenges with measuring ammonia concentration?

  • Want to measure safely without using sulfuric acid or other hazardous substances
  • Want to measure continuously
  • Want to measure accurately without being affected by gas chromatography tailing

Solution from HORIBA

Multi-Component Analyzer VA-5000 Series and its Advantages

  • Continuous monitoring of ammonia concentration

Utilizes non-dispersive infrared (NDIR) absorption technology, enabling long-term stable and continuous NH3 measurement.

  • Wide measurement range 

Available with maximum 0-100 vol% and minimum 0-100 ppm measurement ranges (only for dry gas).

  • Equipped with multiple detectors 

Supports up to three NH3 detectors for parallel installation and simultaneous catalytic reaction monitoring.

User Voice

Enables continuous and safe ammonia analysis without manual labor, replacing traditional complex and hazardous processes

Before implementing the system, conductivity had to be measured manually while adjusting sulfuric acid concentrations to match ammonia levels, making  the process both complex and hazardous. With the VA-5000, measurements are now automated and safe, allowing for a larger number of experiments.
