Kinetic modeling of the hydrocracking of polystyrene blended with vacuum gasoil

The kinetic modeling of the hydrocracking a mixture polystyrene (PS) and vacuum gasoil (VGO) over PtPd/HY catalyst has been carried out. reactions have performed in batch reactor under following conditions: 380–420 °C; 80 bar; content PS feed, 10 wt%; catalyst/feed ratio, 0.1 mass; time, 30–300 min. Different reaction networks models studied, which evolution product distribution (unconverted PS, dry gas, liquefied petroleum gases, naphtha, light cycle oil, heavy oil coke) with extent time quantified by considering three different simultaneous deactivation mechanisms (plastic fouling, coke deposition metal poisoning). model selected (based on 7-lump network) used for performing parametric study, determining that 400 °C 180 min are optimal conditions maximizing yield naphtha (35 wt%) at same is totally converted. This original may act as basis scaling-up studies focused large-scale valorization waste plastics co-feeding them into unit Waste-Refinery.
