1. A method for producing olefin from waste plastic feedstock and kerosene and/or another source(s) of hydrocarbons comprising the steps of:
providing a first feed stream comprising kerosene and/or another source(s) of hydrocarbons;
pre-fractionating the first feed stream by separating and removing both a light hydrocarbon stream comprising C8 and lighter hydrocarbons, and a heavier hydrocarbon stream, from hydrocarbons that are selected for further processing, thereby producing a first heart cut paraffin stream comprising C10-C18 hydrocarbons;
hydrotreating a second feed stream comprising waste plastic feedstock comprising C10-C18 hydrocarbons;
combining the first heart cut paraffin stream with the second feed stream to form a combined stream;
hydrotreating the combined stream;
fractionating the hydrotreated stream to remove paraffins that are heavier and/or lighter than the heart cut range to form a second heart cut paraffin stream;
dehydrogenating the second heart cut paraffin stream to form a stream comprising olefins;
purifying the stream comprising the olefins;
alkylating the stream comprising the olefins with benzene to produce an alkylbenzene; and
sulfonating the alkylbenzene to form an alkylbenzene sulfonate surfactant.
