AM-94-64 COMMERCIAL EXPERIENCE WITH NEW-GENERATION UNICRACIUNG CATALYSTS

Description:

In response to today’s refining needs, Unocal and UOP have developed a new generation of hydrocracking catalysts, which have been installed in hydrocrackers worldwide. This paper discusses’some of the critical elements in hydrocracking catalyst design, with emphasis on showing how knowledge of the interplay between catalyst components, feed types and operating conditions can lead to catalyst products which better fit the needs of the refiners. Also presented are commercial examples of (a) new applications for recently introduced Unicracking catalysts and (b) first-time applications for new catalysts. Data from commercial units show how changes in hydrocracker operating mode, coupled with a judicious choice of catalyst, can lead to significant economic benefits.
