Abstract
Systems and methods are provided for integration of polymeric waste co-processing in cokers to produce circular chemical products from coker gas oil, including 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; and converting the coker gas oil into at least a polymer.
