摘要：Lumping of the residue charge stock is based on saturate, light and heavy aromatics, soft and hard resins, as well as asphaltenes, whose concentrations can be obtained by solvent sedimentation and Al2O3 column separation. The reaction scheme contains 11 lumped species, including two middle fractions, naphtha, gas, and coke in addition to the above six lumps for residua. It is shown that these kinetic parameters are all invariant with respect to residue compositions and therefore this model is able to predict yields of delayed coking products for a wide variety of ranges of charge stock and operating conditions beyond that of the tests.
