Effect of 1-Methylnaphthalene Solvent on Cracking of Oil Sand Bitumen with Iron Oxide Catalyst in Steam Atmosphere
Oil sand bitumen Steam catalytic cracking Iron oxide catalyst 1-Methylnaphthalene
2010/9/8
Catalytic cracking of bitumen with steam was examined. The heavy oil fraction of bitumen reacted with active oxygen species generated from steam with the iron oxide catalyst, producing significant amo...
Deep Hydrotreatment of Middle Distillates Obtained by Pyrolysis of Oil Shale and Oil Sands Bitumen
Shale oil Oil sands bitumen Middle distillate Deep hydrotreatment Nitrogen pre-removal
2010/9/8
Middle distillates obtained by pyrolysis of oil shale and oil sands bitumen were denitrogenated by complex formation with CuCl2·2H2O, which reduced the nitrogen contents from 9900 to 2700 wtppm and fr...
