Digitized edition from print [produced by Natural Resources Canada]. "February 1973." Includes bibliographical references (page 12). "This is the fourth report in a series (1, 2, 3) on the investigation of techniques for hydrocracking residual oils and tars. In the third report the effect of gross concentrations of mineral matter (1 to 4 %) on the thermal and catalytic hydrocracking of Athabasca bitumen were described. This report is concerned with the effects of low concentrations of clay and silt (<1 %) in bitumen feed stocks, with a view to determining whether the deposition of mineral matter on the catalyst surfaces is the prime cause of the de-activation observed in the catalytic process. The experiments were done in the liquid phase in a bottom-feed, continuous-flow apparatus"--Introduction, page [1]. Includes abstract in French. Bitumen Catalyst de-activation Soutar, P. S., author.
