Abstract

Tubular reactors are used in the production of fixed bed phthalic anhydride. The shape of the catalysts in this process is quite diverse - worms, pieces, truncated cones, balls, Raschig rings, various shapes. All this, as shown by experimental data, reduces the efficiency of the catalysts both due to the different loading of the catalyst on the feedstock and due to the appearance of hot spots in the catalyst bed, leading to catalyst sintering.
