Abstract: Based on the maximum Shannon entropy states and partial physical properties of reforming feedstock, the change of molecular level of reforming feedstock during Delta-Base data generation was studied. The maximum Shannon entropy as the objective function was used, the relative molecular mass, the ratio of hydrogen to carbon, the composition and density of PIONA and the potential content of aromatics were taken as constraints, and the Delta-Base data of two different aromatics reforming feedstocks were calculated from the molecular level. The results showed that the mass fraction of aromatics in the product increased with the increase of the potential content of aromatics. The Delta-Base data can be generated by the molecular level mechanism model.
