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...

Fall 2015
Oil sands found in Athabasca and Cold Lake regions of Northern Alberta form Canada’s primary source of energy reserves. Asphaltenes, a significant part of bitumen is often considered to be the least valuable component of crude oil due to various factors such as difficulty in transporting and...

The kinetics of the thermal decomposition of Athabasca vacuum residue (AVR) has been studied by thermogravimetric analysis. Three heating rates of 0.5, 10 and 25 K/min were used to investigate the consistency of kinetic parameters. The Weibull and Gaussian distribution functions were found to be...

Growth of oleaginous yeasts on mixed C5 and C6 sugar streams to generate lipid feedstocks for renewable hydrocarbon production
DownloadSpring 2022
Microbial lipids are a promising feedstock to produce renewable fuels. Lignocellulosic feedstocks can provide multiple carbon sources for microbial growth, such as hexoses (C6) and pentoses (C5). Oleaginous yeasts can convert C5 and C6 sugars to microbial lipids that can be further processed into...

Hydrogen can be produced from biomass; this hydrogen is called biohydrogen. Biohydrogen produced in Western Canada can partially contribute to meeting the demand for hydrogen needed for bitumen upgrading. Gasification and pyrolysis are two promising pathways for producing biohydrogen in a...

Measurements of Methane Pyrolysis in a Constant Volume Batch Reactor at High Temperatures and Pressures
DownloadFall 2021
Methane pyrolysis is a process used to generate hydrogen gas and carbon black without the creation of carbon dioxide. Methane pyrolysis in a constant volume batch reactor was investigated at temperatures of 892 K, 1093 K, and 1292 K with reaction times of 15 s, 30 s, 60 s, 180 s, and 300 s with...

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...
