Plastic treatment process

Abstract

The invention provides a process for the treatment of mixed plastic waste, said process comprising the following steps, in sequential order: a) converting a mixed plastic waste to a pyoil in a pyrolysis reactor; b) contacting at least a portion of the pyoil with a catalyst in the presence of hydrogen in a hydrotreatment unit to produce a hydrotreated pyoil; c) separating the hydrotreated pyoil into at least two fractions, wherein one of said fractions is a heavy fraction, preferably at least three fractions: a light fraction, a medium fraction and a heavy fraction, in a separating unit; and d) feeding the heavy fraction to a catalytic cracking reactor to produce a cracked heavy fraction.
