Abstract
A process is provided for utilizing polypropylene-containing waste plastic. The process provides pyrolyzing a plastic feed in a pyrolysis reactor to obtain a pyrolysis effluent stream. The process further provides passing the pyrolysis effluent stream to a distillation column to obtain a Chydrocarbons rich stream which is also dimethylheptenes rich and then passing the Chydrocarbons rich stream to a reforming unit to provide a reformate stream. The process further provides passing the reformate stream to a transalkylation unit to provide a mixed-xylenes stream.
