Choosing high performance LTS catalyst for improved efficiency

In an increasingly competitive market, catalyst selection is of significant importance when it comes to optimizing performance in ammonia and hydrogen plants. By installing high performance catalysts, it is possible to improve the overall plant efficiency and ensure optimal feedstock utilization, thereby increasing profit margin.

在传统的氨植物中，一氧化碳对氨合成所需的氢的最终转化在低温换档（LTS）催化剂上发生。这使得LTS催化剂成为植物中最重要的催化剂之一，其性能的甚至小的变化都会对运营成本产生重大影响。通过选择高性能LTS催化剂，可以大大提升整体工厂效率，导致显着的生产收益。

Fundamental research

A fundamental understanding is the key to all new developments. Consequently, a significant part of our research activities is focused on long-term and fundamental research.

The objective for our research efforts within the area of LTS conversion is at all times to provide our customers with state-of-the-art products that meet the requirements for cost-effective ammonia and hydrogen production. A high performance LTS catalyst must be optimized with regard to key parameters such as activity, stability, selectivity and poison resistance.

We wanted to develop a catalyst superior in all aspects for efficient low temperature shift conversion and that work resulted in a new generation of low methanol LTS catalyst,LK-853 FENCE™.

LK-853 FENCE™ is a result of our fundamental research efforts.

杰出的表现

LK-853 FENCE™ is a state-of-the-art catalyst forammonia和hydrogenproduction, offering extraordinary advantages for our customers. LK-853 FENCE™ is used in ammonia and hydrogen plants for the conversion of carbon monoxide via the water-gas shift reaction. It is cesium promoted for minimum methanol by-product formation.

自20世纪90年代后期以来，前身，LK-823, has been recognized as the most active, commercially available low methanol LTS catalyst. During the development of LK-853 FENCE™, LK-823 has been used as the benchmark catalyst. The benefits of LK-853 FENCE™ include consistently higher conversion rates, increased poison resistance, low methanol formation and prolonged catalyst lifetimes.

Economical gain from using premium LTS catalyst.

FENCE™ technology

The knowledge gathered throughout the years has been combined and constitutes the foundation of the FENCE™ technology, which is the basis for low methanol LTS catalyst, the LK-853 FENCE™.

The basic principle of the FENCE™ technology is to stabilize the finely dispersed copper nanoparticles in the catalyst by creating a separation between them of multiple oxide particles. The FENCE™ technology creates a picket fence of metal oxide crystals that prevent sintering of the copper crystals, which ensures high stability of the active sites over the catalyst lifetime.
