Process for co-conversion of waste plastics and hydrocarbon feedstock

A method for co-conversion of waste plastics and hydrocarbons into lighter distillate products, the method comprising:

• a) spray feeding a hydrocarbon feed in a bottom section of a riser reactor through injection nozzles;
• b) feeding hot regenerated catalyst from a regenerator vessel into the bottom section of the riser reactor to allow contacting with the hydrocarbon feed;
• c) feeding a lift fluidization media into the bottom section of the riser reactor;
• d) conveying a waste plastic from a supply vessel to the bottom section of the riser reactor, to allow thermal decomposition of the waste plastic into lighter molecules and catalytic cracking of the same by contacting with the hot regenerated catalyst during an upward motion through the riser reactor, wherein the waste plastic comprises metal containing polyethylene-polypropylene multilayer plastics;
• e) separation of the hot regenerated catalyst and product vapors by means of riser termination devices;
• f) separation of hydrocarbon molecules from the catalyst by steam stripping in a stripper vessel;
• and
• g) separation of the product vapors into different product fractions comprising Naphtha, Light cycle oil, Heavy cycle oil, clarified oil by a fractionator column.
