O4-35
O4-35 is designed for the oxidation of naphthalene (naph) or a mixture of naph and o-xylene (o-x) to phthalic anhydride (PA). The latest generation 5-layer O4-35 consists of 3 selective layers (CL1-CL3) and 2 active layers (CL4-CL5). The additional selective layer allows naph loading up to 90 g/Nm3. The CL4 and CL5 layer are adjusted to achieve maximum performance and a superior PA quality.
