✦ Synopsis

Previous work on direct oil sand heating showed that hydrocarbon removal of wQO% could be achieved below a temperature of ~550%

It was also found that the rate of heat-up did not affect.the total yield. In the present work, the influence of various parameters, including heating rate, on the yield distribution of products from directly heated oil sand and separated bitumen was examined using gas chromatography.

It is found that the heating rate has a very dramatic influence on the distribution of products. Fast heating rates cause a strong shift to lighter species in either inert or chemically reactive atmospheres. It is possible to achieve a very wide range of distribution of products by employing suitable values of heating rate and final temperature. Increasing hydrogen pressure is found to have a significant influence on the yield distribution up to ~3 MPa, after which point, little further change is observed.
