Hydrocracking Pretreat Solutions

Enable Premium Yields from Heavy Feedstocks

Advanced pretreatment for maximum cracking efficiency.

Our hydrocracking pretreat catalyst portfolio is engineered to remove metals, sulfur, and particularly basic nitrogen, while maximizing aromatic saturation and volume swell. These advanced NiMo and Bulk Metal catalyst solutions enhance feed quality for downstream cracking sections, extending hydrocracking catalyst life and enabling superior yields of clean, high-value products. Combined with our technical excellence in complex catalyst system design, we help refiners maximize profitability from low-value heavy gas oils.
