Abstract
An increasing portion of the world’s oil reserves consist of heavy
oil that produces low yields of useful products when processed with
existing coking technologies. In the UOP UniflexTM process, the
coke yield is lower and the product yield is higher. Here the
catalyst, a non-stoichiometric, crystalline ferrous sulfide, is
formed in-situ from ferrous sulfate. Although molybdenum catalysts
have a stronger hydrogenation function than iron, molybdenum is
expensive and cannot be used as a disposable catalyst. UOP Research
has evaluated numerous alternative catalysts and identified a
superior Fe/Al/O catalyst, which forms nano-crystallites of the
active sulfide form, as the preferred one. The activity,
selectivity, and the stability of a catalyst depend on the various
physical and chemical properties of the intermediate ferrous
sulfide. This talk will focus on the factors that show the
superiority of the Fe/Al/O nano-catalysts for slurry hydrocracking
of heavy oil.
