Integration of polymeric waste co-processing in cokers to produce circular chemical products from coker gas oil

A method of producing circular chemical products comprising:

• providing a coker gas oil that is at least partially derived from polymeric waste, wherein the coker gas oil has a paraffin content of about 5 wt % to about 50 wt %, a sulfur content of about 0.1 wt % to about 7 wt %, and a halide content of about 0.1 wppm to about 5 wppm;
• hydroprocessing at least a portion of the coker gas oil to form at least a hydroprocessing effluent;
• steam cracking at least a portion of the hydroprocessing effluent to form at least a steam cracking effluent;
• recovering olefins from the steam cracking effluent;
• and
• polymerizing at least a portion of the olefins to form at least polyolefins.
