Method of treating waste plastic

Abstract

A method of upgrading liquefied waste plastic (LWP) to a mixture of purified hydrocarbons is hereby provided. The method includes the steps of providing a feed including liquefied waste plastic (LWP) and a vacuum gas oil (VGO) stream and/or a heavy gas oil (HGO) stream to form a mixed stream, subjecting the mixed stream to hydrotreatment for removal of impurities and to produce a hydrotreated stream, subjecting the hydrotreated stream to hydrocracking to produce a hydrocracked stream including a mixture of purified hydrocarbons and fractionating the hydrocracked stream.
