Axens SeLene selective hydrogenation catalysts new family 5/20/2021 Axens announced the launch of SeLene, a newly created family brand dedicated to selective hydrogenation. Selective hydrogenation is an essential purification step for the production of the most critical building blocks of the petrochemical industry. These blocks include ethylene, propylene, butadiene and aromatics. Selective hydrogenation is also applied in several refinery processing schemes, and plays an increasingly important role in the widely adopted, fully integrated, refinery and petrochemical operation. Axens proposes a broad catalyst portfolio to deliver optimal performance, specifically tailored for the selective hydrogenation needs of the customers thanks to over 50 years of powerful innovation aimed at improving the active phase impregnation, combined with state-of-the-art alumina carriers.
