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...

An optimized process design for oxymethylene ethers production from woody-biomass-derived syngas
Download2016-01-01
Zhang, Xiaolei, Oyedun, Adetoyese Olajire, Kumar, Amit, Oestreich, Dorian, Arnold, Ulrich, Sauer, Jorg
The conversion of biomass for the production of liquid fuels can help reduce the greenhouse gas (GHG) emissions that are predominantly generated by the combustion of fossil fuels. Oxymethylene ethers (OMEs) are a series of liquid fuel additives that can be obtained from syngas, which is produced...

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...

Underground Coal Gasification (UCG) is a process in which coal is converted to syngas in-situ. UCG has gained popularity recently as it could be used to extract energy of deep-lying coal seams, and it reduces the footprints attributed to the gasification process. In this study, two models have...

Characterization of asphaltene molecular structures by cracking under hydrogenation conditions and prediction of the viscosity reduction from visbreaking of heavy oils
DownloadSpring 2013
The chemical building blocks that comprise petroleum asphaltenes were determined by cracking samples under conditions that minimized alterations to aromatic and cycloalkyl groups. Hydrogenation conditions that used tetralin as hydrogen-donor solvent, with an iron-based catalyst, allowed...

In a recent construction project, a platform structure made up of 350W and 300W steel underwent a double dip galvanizing process. Prior to the galvanizing process, the platform was fabricated to completion, which included numerous welds throughout the design. After galvanizing, cracks were found...

Spring 2012
The effect of blending woody biomass material with fluid coke and coal on the co-pyrolysis process was investigated in an entrained flow gasifier. The SEM results showed a particle size decrease and shape change from needle to spherical as the temperature was increased. Agglomeration between...

Experimental and numerical verifications of new methods to predict gasification kinetics of char from MSW (Municipal Solid Waste) components using the TGA
DownloadFall 2021
Thermogravimetric Analyzer (TGA) is a standard state-of-the-art instrument used for investigating char gasification kinetics. However, one major flaw of the TGA is the build-up of a stagnant gas region between the empty space of the crucible mouth and the char sample layer which leads to poor...
