Catalyst systems offer flexibility for hydroprocessing applications

Refinersa re strongly motivated to evaluate and select premier catalyst systems for the production of both diesel products from their hydrocracking and diesel treating units.

The dynamics of global gasoil (GO) and ultra-low-sulfur diesel (ULSD) demand are driven by regulatory demands for transport diesel and evolving needs for vastly improved marine-bunker quality in specific emission control areas (ECAs), as well as in economic growth. It is expected that this will drive regional variability in ULSD/0.1% sulfur GO differential over time and consequently provide incentives for refiners to maximize flexibility in both hydrocracker distillate yields and ULSD unit performance. Adding in an expectation of gasoline supply becoming long in the Middle East over the next several years, the refiner is further motivated to evaluate and select premier catalyst systems for t
