Abstract:
A process for making a heavy wax composition comprising the steps of:(a) passing a waste plastics feed comprising polyethylene to a pyrolysis zone, having a sub-atmospheric pressure, whereby at least a portion of said waste plastics feed is cracked, thereby forming a pyrolysis zone effluent comprising 1-olefins and n-paraffins;(b) passing at least a portion of said pyrolysis zone effluent to a catalytic hydrotreating zone wherein at least a portion of said pyrolysis zone effluent is contacted with a hydrotreating catalyst at hydrotreating conditions, thereby producing a hydrotreated pyrolysis zone effluent; and(c) wherein said hydrotreated pyrolysis zone effluent comprises a wax having a melting point of at least about 100.degree.
