The kinetic and experimental study for the pyrolysis of hydrotreated and non-hydrotreated coking distillated fractions

The purpose of this study is the pyrolysis of the distilled fractions obtained in the coking process as such and hydrotreated with the aim of diversifying the feedstock used in pyrolysis. The application of hydrotreating followed by pyrolysis, determines the reduction of the aromatic and olefinic hydrocarbons content in the feedstock, which leads to the improvement of the distribution of the reaction products and the decrease in the level of coke deposits, compared to the pyrolysis of non-hydrotreated distillate fractions. This study also aims to calculate the kinetic parameters of the pyrolysis process for non-hydrotreated and hydrotreated coking fraction at three equivalent temperatures: T = 680 °C, T = 695 °C, T = 705 °C.
