of High Performance Selective Hydrogenation Catalysts
Selective hydrogenation is the best technology when it comes to purifying highly valuable olefinic and aromatic
streams produced by steam crackers and FCC units.
Axens’ latest generation of high performance selective hydrogenation catalysts combines state-of-the-art
alumina carriers and cutting edge metal impregnation technologies. High activity, easy regeneration highly
competitive cost-to-fill, are among the key advantages of these catalysts. They include LD 485 (Pd-based), LD
465 (Pd-based), LD 541 (Ni-based), LD 551 (Ni-based), mainly for first stage Pygas hydrogenation, and HR 606
(CoMo) for second stage Pygas hydrogenation.
reference is the result of a close collaboration with Galp, an important actor in the European refining
market. In the framework of a catalyst replacement in a Galp selective hydrogenation unit that historically used
palladium-based catalysts, Axens recommended a new approach by loading LD 541, a nickel-based catalyst, due
to specificities in feedstock and operation of this particular unit. “Thanks to this new approach, Galp has
significantly improved the unit’s operation in terms of performance and cycle length, illustrating thus the
efficiency of the relation between Axens and Galp”, stated Yoeugourthen Hamlaoui, Technologist Hydrogenation
& Reforming at Axens.
With this latest generation of catalysts, the Galp Selective Hydrogenation unit performs successfully in terms of
selectivity and conversion, as it also uses for the first time the multi-awarded in first stage Pygas hydrogenation
Galp (www.Galp.com) is a publicly held, Portuguese-based energy company, with an international presence. Galp’s
activities cover all stages of the energy sector's value chain, from prospection and extraction of oil and natural gas
from reservoirs located kilometers under the sea surface, to the development of efficient and environmentally
sustainable energy solutions for customers – whether large industries that seek to increase their competitiveness, or
individual consumers that seek the most flexible solutions for their home and mobility needs. Galp also contributes
to the economic development of the 11 countries where we operate and to the social progress of the communities
that welcome us. Galp employs 6,389 people.
