Ultra-Deep Diesel Hydrotreating Catalyst Supply for a Major Refinery

A 3-million-ton/year diesel refining unit at a large private refinery in Shandong, processing heavy high-sulfur crude. The previous Western imported catalyst failed to meet desulfurization targets, deactivated rapidly within 3 months, and replacement cost was extremely high.

Leveraging Sinopec FRIPP's flagship FH-UDS technology, we delivered a customized Ni-W composite ultra-deep hydrotreating catalyst for high-impurity duty, with optimized support pore structure and heavy-metal poisoning resistance.

• Diesel sulfur stabilized below 10ppm, fully meeting Middle East clean fuel standards
• catalyst run length greatly extended with 35% lower overall operating costs. Successfully replaced the full imported hydrogenation range and established a long-term annual supply agreement.
