The "all components hydrocracking model"

The conversion of syngas through the Fischer–Tropsch (FT) process leads to the formation of products, essentially made up of a mixture of n-paraffins, which need to be subjected to a hydrocracking process in order to improve both yields and properties of middle distillates. The paper presents the evolution of a previous lumped model; the actual one is able to reproduce the outlet stream composition since it satisfies the material balance of each component and provides kinetic constants that depend on the number of carbon atoms.
