Axens Offer
With over 170 commercial references, the Symphony® catalysts offers advantages, such as improved specific surface area retention.
Higher specific surface area is associated with improved regeneration (Pt re-dispersion) and better chloride retention. Consequently, the new catalysts exhibit longer catalyst life, reduced salt deposits in downstream units and lower chloride content in the hydrogen rich gas, resulting in longer chloride trap life, and lower green oil formation.

Reforming catalysts developed to maximize aromatics production from naphtha.
Symphony® AR 151
Symphony® AR 151 has industry leading hydrothermal stability and attrition resistance. It offers high yield and the lowest coke make.
Semi-Regenerative Reforming
Semi-Regenerative reformer target is to produce an high octane stream for gasoline production but also aromatics for petrochemical application and high purity hydrogen used by other refinery processes. Typically semi regenerative units consist of 3 to 4 reactors, the regeneration is performed for all reactors at the same time leading to periodic unit shutdown.
Symphony® PR 150
Symphony® Reforming catalyst family uses an enhanced and optimized alumina carrier to more effectively upgrade naphtha into high-octane reformate, hydrogen and aromatics. Thanks to its balanced formulation, Symphony® PR 150 is the catalyst of choice for cyclic operation and units having quite high sulfur content on the feed.
Symphony® PR 156
Symphony® Reforming catalyst family uses an enhanced and optimized alumina carrier to more effectively upgrade naphtha into high-octane reformate, hydrogen and aromatics. Thanks to its unbalanced formulation Symphony® PR 156 is the catalyst of choice for semi regenerative unit providing maximum cycle length.
RG 682
RG 682 assures the optimum interaction between promoter, platinum and rhenium. It procures an increase of C5+ and H2 in addition to an extended cycle length as a consequence of a drastic increase of activity and stability.
Symphony® PR 250
Symphony® Reforming catalyst family uses an enhanced and optimized alumina carrier to more effectively upgrade naphtha into high-octane reformate, hydrogen and aromatics. Thanks to its balanced formulation, Symphony® PR 250 is the catalyst of choice for cyclic operation and units having quite high sulfur content on the feed. PR 250 offers versus PR 150, linked to optimization of the catalytic formulation, improvement in activity and cycle length ensuring improved economic.
Symphony® PR 256
