1. A method for simultaneously:
(a) reducing coke formation;
(b) increasing yield of distillate;
(c) converting a waste plastic into a useful chemical commodity;
(d) reducing formation of coke deposits on walls of the processing unit; and
(e) reducing fouling caused due to deposits of coke products on walls of the processing unit,
during a pyrolytic or cracking processing of a material comprising:
