High-End Catalytic Import Substitution for an Aromatics PX Unit

A Middle East fine chemical aromatics unit with constrained toluene/xylene deep-processing capacity. High-end disproportionation and isomerization catalysts long depended on imports — long lead times, high prices, and no after-sales support.

Based on Sinopec SSPC core technology transfer, we supplied a full set of high-end toluene disproportionation and xylene isomerization catalysts adapted to continuous PX unit operation.

• Aromatics conversion and selectivity reached parity with imports, with benzene + xylene selectivity stably ≥97%, breaking the overseas technology monopoly
• delivery lead time cut by 60%, with full commissioning guidance — a benchmark localization case for regional aromatics units.
