Diesel/LCO Hydrotreating Solutions

Maximizing Middle Distillate Value

Industry-leading technology for ultra-low sulfur diesel production.

Our Diesel/LCO Hydrotreating catalyst portfolio is engineered to convert challenging low-value feeds, including cracked feedstock, into premium ultra-low sulfur diesel. Our solutions deliver exceptional desulfurization, aromatics saturation, and cetane improvement while extending cycle lengths and optimizing hydrogen usage. Paired with our proprietary STAX™ design methodology and operational expertise, we help refiners maximize middle distillate value and profitability.

Product Highlights

PULSAR®

Industry-leading hydrotreating catalyst platform delivering exceptional desulfurization, denitrogenation, and aromatics saturation with outstanding cycle length for low and medium pressure distillate hydrotreating and FCC-PT applications.

QUASAR™

Highest-performance catalyst platform for high-pressure distillate hydrotreating and HC-PT. This technology maximizes HDS, HDN, and aromatics hydrogenation allowing to maximize upgrading of distressed feedstocks and volume swell.

STAX™ Loading System

Proprietary catalyst loading methodology optimizing bed configuration for maximum performance.

Celestia™ and Nebula™ BMC (Bulk Metal Catalysts)

Revolutionary bulk metal technology through our Galexia™ partnership with ExxonMobil providing unmatched hydrogenation and nitrogen and sulfur removal capability for the most challenging feedstocks.

STARS™

Well-established, high-performance catalyst technology that enables application across a wide range of processes from naphtha hydrotreating to HC-PT to deliver highly reliable, robust performance.

ReNewFine™

Specialized catalyst technology enabling efficient processing of renewable feeds including bio-oils and waste-derived feedstocks maximizing cycle length and yields.

Guard Bed Solutions

Multi-stage guard beds protecting the main catalyst beds from contaminants while extending overall cycle length.

Hydroprocessing Leadership

Advanced catalysts and process technologies engineered to strengthen refinery performance and fuel quality.

Hydroprocessing sits at the center of modern refining performance. Ketjen develops catalysts and process technologies that enable refiners to improve conversion, manage feedstock variability, and meet tightening fuel specifications while protecting margins. With over 50 years of hydroprocessing expertise, we help customers turn operational complexity into measurable performance gains.
