In the upgrading of heavy oil fractions by catalytic hydrogenation (hydroprocessing), the catalytic activity decreases through the deposition of a carbonaceous material (coke) in the pore system. A precise knowledge of the way this coke is formed would be of value in predicting process performance. The aim of this research project (1988-90) was to describe the physics and chemistry of this coking effect. It examined in particular the mechanisms by which coke is formed, the structures that result, the location of coke deposition sites in the pore system and in the catalyst bed, and the relationship between the deactivation effect and the distribution of the coke.
