Compatibility of feed for hydrocracking and FCC with scrap tires and waste plastics pyrolysis oil residue

Popis výsledku v původním jazyce

In contrast to residual fractions of petroleum hydrocarbons, pyrolysis oil residues (boiling above 360 degrees C) from chemical waste represent an underexplored feedstock. The primary issue that will need to be addressed in their coprocessing in oil refineries by cracking technologies will be compatibility with petroleum hydrocarbons. From a variety of recommended methods, a combination of SARA group analysis, standard and digitized spot test, and optical microscopy were used to evaluate the homogeneity and compatibility of standard feed for hydrocracking and FCC with scrap tires and waste plastics pyrolysis oil distillation residue in the concentration range of 0-100 wt%. A total of 40 samples were evaluated. It has been shown that the behavior of these blends is difficult to predict, as it is highly dependent on the particular blend and the concentration of the components contained. Notably, the most significant compatibility issues were observed at low concentrations of one feed in the other-a critical insight for the coprocessing of pyrolysis oil residues. Overall, blending hydrocracking feed with waste plastics pyrolysis oil residue, and FCC feed with scrap tires pyrolysis oil residue, showed the most favorable compatibility profiles.
