Bitumen Properties The bitumen sample from Athabasca has API gravitiy of around Fig.7 and Fig.8 show dependency of bitumen density and viscosity on temperature respectively.

It is infered that the bitumen has less mobility at low temperature in original resevoir condition. Fig.9 shows the P- andFile Size: 1MB.

Catalytic hydrocracking activity was estimated by analyzing H/C mole ratio based on EA data, and TGA was employed to compare the thermal behavior of bitumen before and after reaction.

Upon hydrocracking over Mo/MCF catalyst, H/C was increased from (bitumen itself) to Key words: Oil Sand, Bitumen, Hydrocracking, Catalyst, TGA INTRODUCTION. Thermal cracking appears to be the principal mechanism operating during hydrocracking of Athabasca bitumen, under the investigated conditions.

The main identified chemical transformations of the bitumen heavy ends during hydrocracking include dealkylation, increase in aromaticity and decarboxylation.

In general terms, the quality of tar sand bitumen is low compared to that of conventional crude oil and heavy oil. The high carbon residue of heavy oil and bitumen dictate that considerable amounts of coke will be produced during thermal refining (see Table 1.)

Athabasca bitumen [7] is extended to predict the overall sulfur removal and weight fraction of sulfur in different boiling fractions of the liquid products. Methods and Materials. The feed used in this study was topped Athabasca bitumen.

The properties of the feed are summarized in Table I. The experimental apparatus (a continuous stirred-basket. 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 Coordinates: 57°01′N °39′W /.

Given enormous capital costs, operating expenses, flue gas emissions, water treatment and handling costs of thermal in situ bitumen recovery processes, improving the overall efficiency by lowering energy requirements, environmental impact, and costs of these production techniques is a.

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. Hydrocracking of Athabasca Bitumen Kinetics of Formation of Gases.
