This latest generation of catalysts includes [LD 485](https://www.axens.net/product/catalysts-a-adsorbents/5016/ld-485.html) (Pd-based), [LD 465](https://www.axens.net/product/catalysts-a-adsorbents/136/ld-465.html) (Pd-based), [LD 541](https://www.axens.net/product/catalysts-a-adsorbents/180/ld-541.html) (Ni-based), [LD 551](https://www.axens.net/product/catalysts-a-adsorbents/20098/ld-551.html) (Ni-based), mainly for first stage pygas hydrogenation, and [HR 606](https://www.axens.net/product/catalysts-a-adsorbents/20068/hr-606.html) (CoMo) for second stage pygas hydrogenation.   ![Pygas-Value-Chain-750x156](https://blog.axens.net/hs-fs/hubfs/Pygas-Value-Chain-750x156.jpg?width=750&name=Pygas-Value-Chain-750x156.jpg) Typical pygas upgrading scheme   Axens Solutions’ received a **very positive feedback from the market** for these catalysts including head-to-head comparisons in industrial unit operation and several repeat orders. This success is confirmed by their rapidly growing reference lists.   The **100th Award of Axens Solutions’ latest generation of high performance selective hydrogenation catalysts** is the result of a close collaboration with [Galp](https://www.galp.com/corp/en/), an important actor in the European refining market. In the context of a catalyst replacement in a Galp C4 selective hydrogenation unit using historically palladium-based catalysts, Axens Solutions recommended as a novel approach to load [LD 541](https://www.axens.net/product/catalysts-a-adsorbents/180/ld-541.html), a nickel-based catalyst, due to specificities in feedstock and operation of this particular unit.   This 100th award performs successfully in terms of butene-2 maximisation and butadiene conversion, and is also the first reference for LD 541 (multi-awarded in first stage pygas hydrogenation) in a [C4 hydrogenation](https://www.axens.net/our-offer/by-market/petrochemicals/olefins-pygas-purification-and-conversion/13/c4-total-hydrogenation.html) unit. ## Subscribe to our business newsletter to learn more about Axens [![Subscribe](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/5476842/54f23149-756d-4484-9404-894552391aac.png)](https://hubspot-cta-redirect-eu1-prod.s3.amazonaws.com/cta/redirect/5476842/54f23149-756d-4484-9404-894552391aac) ## Articles that might interest you ![chat-bkg](https://blog.axens.net/hubfs/Markentive/images/chat-bkg.jpg) ## Let’s see what we can achieve together.
