摘要: Based on the characteristics of composition and hydrotreating reactions of residue, new definitions of virtual molecular-group components about CH and CH2 are proposed here. The new reaction, hydrogenation of CH to CH2 (HDCH), can be used to represent the change of C and H with reaction conditions in residue hydrotreating. Meanwhile, by using the lumping approach, the kinetic models of HDCH, HDS, HDN, HDCCR, HDM, HDNi and HDV reactions are established. They are key components of the new kinetic model for residue hydrotreating based on chemical reaction sections. During the process of constructing the kinetic model, the goodness-to-fit (R2) between test data and model data is set as target value, and the parameters of the kinetic model can be calculated accurately. In verification test, the predict content of H, S, N, CCR, M, Ni and V obtained using the kinetic model can match well with the test data.
