Thermal cracking of Athabasca bitumen was carried out in an oilsand packed-bed column, in the presence and absence of in situ prepared trimetallic nanocatalysts at a pressure of MPa, residence. Ultradispersed (UD) catalysts enhanced the upgrading of Athabasca bitumen by increasing the hydrogen/carbon ratio and reducing both viscosity and coke formation.
The conversion of bitumen increased with both the temperature and reaction time, whereas viscosity, sulfur, and microcarbon residue (MCR) in the reaction products by: effect of hydrocracking athabasca bitumen on sulphur-type distribution in the naphtha fraction.

different asphaltenes content in presence and absence of. In this study, three commonly used isoconversional methods, namely: Ozawa–Flynn–Wall (OFW), Kissinger–Akahira–Sunose (KAS), and the advanced non-linear integral method of Vyazovkin (NLN) were employed for the first time for calculating the activation energy for thermal cracking of Athabasca bitumen under inert by: Thermal cracking reactions are also important for the design of bitumen upgrading facilities.
Although rather extensive studies have been made of thermal cracking reactions involving Athabasca bitumen, most studies reported so far are concerned with the chemical Cited by: SAGD is the methods to produce bitumen by reducing oil viscosity so they flow themselves.
To Monitor the location of the steam front is very important to operate SAGD. In time-lapse seismic analysis, amplitude change caused by decrease in velocity and density is widely used to estimate the location of the steam Size: 1MB.
Bitumen composition is correlated with viscosity measurements and the geology of the host rocks. The results obtained indicate that the bitumen is heterogeneous on a reservoir thickness scale and that a close relationship exists between bitumen composition and viscosity, implying bitumen File Size: KB.

The effects of sulphiding the CoO MoO 3 /Al 2 O 3 catalyst on the hydrocracking reactions were determined and used to conclude that sulphiding of the catalyst, by the sulphur-rich bitumen, occurred during the initial heat-up period of the by: REACTION MODELS Hydrocracking reactions of bitumen and its fractions have been reported as first order with respect to hydrocarbons, zero order with respect to hydrogen and kinetically controlled in the absence of a catalyst6.
approximately one third of the total hydrogen gas is dissolved in the liquid phase when equal volumes of hydrogen and creosote oil were charged into a batch Figure 1 Product yield distribution for CoO-Moi^/Al^C^ catalysed hydrocracking Cited by: Figure 1.
Pressure sensitivity of Athabasca oil density in the range bara versus temperature Viscosity The intrinsic resistance of a fluid to deformation is called viscosity. Principally shear stress (τ) and shear rate (γ) are proportional to each other by viscosity.
Based on this technique the molar mass of Athabasca bitumen was figured out to ± 2 g/mol. Density Oil density measurement is necessary in order to evaluate and characterize the crude oil. Anton Paar apparatus was used to determine the density of Athabasca bitumen at high temperature and high pressure conditions.
The. Experimental Analyses of Athabasca Bitumen Properties This paper introduces experimental measurement of Athabasca heavy crude oil properties and simulation study in a field conditions. The first. There are two basic requirements for heavy-oil recovery processes: first, mobilize the bitumen, and second, have a drive mechanism deliver the mobilized bitumen to a production wellbore.
In situ combustion has the potential to be an important heavy-oil recovery method. Before design of in situ combustion recovery processes can start, it is necessary as a first step to understand the kinetics Cited by: Handbook on theory and practice of bitumen recovery from Athabasca Oil Sands Call Number: TN M37 v Syncrude analytical methods manual for bitumen upgrading Call Number: TP B5 S Syncrude analytical methods for oil sand and bitumen processing Call Number: TP S SAGD (Steam Assisted Gravity Drainage) is one of the most effective methods to produce bitumen (Fig.1).
For seismic monitorin g of the steam front and its effect on the formation, it is important to know correctly the properties of oil sands and bitumen.
low sulfur reduction is not surprising, since thermal hydrocracking has a limited contribution to the sulfur conversion of bitumen residue. The important issue that requires further discussion is the continues sulfur reduction as a function of reaction time.
By contrast, the reduction of molecular weight (Figure 4) approaches an asymptotic value. The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of bitumen or extremely heavy crude oil, located in northeastern Alberta, Canada – roughly centred on the boomtown of Fort oil sands, hosted primarily in the McMurray Formation, consist of a mixture of crude bitumen (a semi-solid rock-like form of crude oil), silica sand, clay minerals, and nates: 57°01′N °39′W / °N.

It has been found that natural zeolite cracking significantly improves the bitumen properties. An average of 80% of liquid hydrocarbon samples recovered from natural zeolite cracked products showed a dramatic decrease in the residuum content, indicating the presence of much lighter.
bitumen. For conventional oil reservoirs, the difference of the effects of oil saturation and water saturation is usually small, but when oil is light and with enough gas dissolved, effect of the oil saturation will show obvious differences from that of water saturation.

Handbook on Theory and Practice of Bitumen Recovery from Athabasca Oil Sands– Volume 1: Theoretical BasisAuthor: Jacob H. Masliyah, Z. Xu, Jan A. Czarnecki. Bitumen Source and Modification Bitumen is derived from the severe biodegradation of lighter crude oil. Typically the type of source material is the predominant factor determining Chemistry and Character of crude oil.
In the case of bitumen the degree of biodegradation has an equal or even greater impact on Chemistry and Character. Although there is a shortage of light petroleum, there is plenty of heavy petroleum rich in macromolecules available, creating an increasing interest for processes that can convert heavy oils to light oils.
Process Chemistry of Petroleum Macromolecules provides the scientific basis for such processes, presenting methods to determine improvement potential.
