Honeywell to assist with cleaner-burning fuels

In conjunction with Unity hydrocracking catalysts, Empresa Nacional del Petroleo (ENAP) has begun using Honeywell UOP’s HYT-6219 Unity hydrotreating catalyst to produce cleaner burning diesel fuel at its Bío Bío refinery in Hualpen, Chile.

The HYT-6219 catalyst pretreats the petroleum feed used to make diesel fuel, removing sulfur, nitrogen and aromatics that would otherwise hurt the performance and longevity of hydrocracking catalysts later in the refining process. The refinery also uses Honeywell UOP's HC-130 and HC-120 Unity hydrocracking catalysts as part of its production process.

Hydrotreating is a critical step in the refining process, where hydrogen and a catalyst are used to pretreat petroleum and other products by removing contaminants before conversion into transportation fuels. The process helps to produce cleaner-burning gasoline and diesel that meet increasingly stringent global fuel regulations such as the Euro V standard, which specifies sulfur content of less than 10 ppm in transportation fuels.

"ENAP chose the Unity catalysts for hydrotreating and hydroprocessing based on their superior economics," said Mike Cleveland, senior business director for Honeywell UOP's refining catalysts product line. "The catalysts meet all of ENAP's demanding performance requirements of less than 5 ppm of sulfur and longer catalyst life."
