MKS Modulares Katalysator SystemTM
Key Enabling Technologies
> Catalyst technology
In more than a decade of intensive research on kinetics and chemical reactions on the catalyst surface the most crucial aspects for the catalyst technology - alloying, wire drawing, surface formation - could be optimised:
-
Influence of alloy types and compositions on the mechanism of primary and secondary reactions during ammonia conversion (adsorption, chemisorption, and desorption processes as well as the nature of fragments on the wire surface)
-
Formation of surface and impacts on the catalyst performance (grain boundary characteristics, migration of Rhodium)
-
Nitrous oxide formation mechanism and development of preventive countermeasures
> Knitting technology
In contrast to conventional mass production of standard gauzes our technology allows to manufacture each gauze individually in any desired modification (knitting type, diameter of gauze and wire, density, alloy composition). As a result the setup of a catalyst pack for a specific burner can easily be changed in case of necessity and will be manufactured within very short time. The flexibility to offer such a wide portfolio of Platinit® and Multinit® gauze types is unique in the market. It allows us to quickly adapt to any desired modification.
> Getter technology
Minimizing net losses of Platinum and Rhodium has recently gained increased importance regarding the tremendous costs of Platinum and Rhodium compared to the price of Palladium. Here we offer a highly sophisticated catchment technology that was originally developed by umicore and has meanwhile been steadily finetuned. The technology reflects the strong correlation between recovery rate, gauze position, and operating conditions and allows to identify the best economic solution for each individual case.
The getter function is mainly determined by the continuous mechanism of surface regeneration and the high reduction potential of Pd due to its high affinity for oxygen. Consequently Pd is capable of reducing the volatile Pt Oxides and simultaneously alloying the Pt metal into the wire. Based on this surface reaction mechanism each getter gauze can recover up to 85% of its own weight from the Platinum primary losses. This way we can easily adjust the desired overall process recovery rate.
