A Preliminary Study on Pyrolysis and Gasification of Asphaltenes and Coal-Asphaltenes Slurry in Entrained Flow Reactor
DownloadFall 2012
The aim of this work is to study pyrolysis of coal-asphaltenes slurry in an atmospheric entrained flow reactor. Athabasca asphaltenes and Genesee coal, both from Alberta in Canada, were selected as the feedstock. Char characteristics and the structure of asphaltenes and slurry chars including...

Athabasca oil sands contain 8 to 14% bitumen and are recovered using surface mining or steam assisted gravity drainage (SAGD). During primary upgrading of bitumen, the vacuum residuum from the distillation column is sent to the solvent de-asphalting unit where a paraffinic solvent is used to...

Pyrolysis of asphaltenes in an atmospheric entrained flow reactor: A study on gasification reactivity and properties of chars
DownloadFall 2014
Solvent deasphalting, followed by asphaltenes gasification, has been recommended as a favorable alternative to coker based upgrading processes. However, very limited work has been carried out on pyrolysis and gasification of asphaltenes, at entrained flow conditions. The present work aims at...
