High-Performance Catalysts for Production of Phthalic Anhydride (PA)
OxyMax™ PA Series
Date d’édition :
décembre 05, 2024
OxyMax™ PA catalysts offer high performance in selective oxidation of o-xylene, naphthalene and mixed feedstocks to phthalic anhydride (PA). They are produced with Clariant’s proprietary fluid-bed coating process. Proprietary promotors optimize activity and selectivity in a multi-layer catalyst design. This enables catalyst solutions to be tailored to individual plant operating conditions and needs.
