title = "Heavy oil upgrading using Fe based slurry catalysts",
abstract = "This research deals with the upgrading of heavy oils using iron based multi-component catalysts. The Fe-Zr-Al catalysts were prepared with precipitation method. The prepared catalysts were evaluated in a batch autoclave reactor using bitumen as feedstock. In order to facilitate the cracking/hydrogenation reactions, the feed was diluted with toluene. Also, water was used as the in-situ source of hydrogen for the reaction. It was observed that the dilution of feed with toluene has significant effects in the low concentration level. The extra heavy oil is slightly decreased with increasing feed concentration up to 30 wt% bitumen, above this concentration range no noticeable change is observed. The coke formation is also increased with the bitumen concentration in the feed. The high concentration of bitumen in the feed at low partial pressure of water causes phase transformation of the catalyst to magnetite, leading to a catalyst deactivation.",
