Hydroprocessing is recognized as one of the primary upgrading steps in the conversion of heavy and residual oils to usable fuels. The chemical reactions which occur result in the reduction of the average molecular weight through cracking and hydrogenation. High yields of good quality liquid product can often be obtained, however, the consumption of high-pressure hydrogen has an important impact on economic considerations. Since the use of high-pressure hydrogen serves mainly in preventing the formation of coke, an assessment of feedstock coking propensity would be useful in the evaluation of the feedstock processability. The coking propensity of a number of different feedstocks was experimentally evaluated and correlated with a selected set of their properties which were determined analytically. The wide range of relevant feedstock properties made it possible to establish their impact on the coking propensity.
