There’s always room for improvement and with this at the forefront of their minds, Giuseppe Bellussi and colleagues from Eni, Italy have focused on “converting the bottom of the barrel” – that is, turning high molecualr weight oil fractions into lighter compounds in the more useful boiling point range.
There are several different technologies that address this (see the Catalysis Science & Technology article for more information) but Bellussi et al. have concentrated their efforts on upgrading the slurry bed technology – a process that so far has seen limited industrial development.
The slurry technology that Eni put their cracking catalyst/Mo2S catalyst to use in
The key to their success in fully converting the heavy and extra heavy oils into the middle distillates was using a dual catalyst – a catalytic system which comprises both a conventional cracking catalyst and nano dispersed molybdenum disulfide, the latter of which is responsible for protecting the cracking catalyst from coke and metal deposition.
