In the polystyrene recycling process, how is benzene produced and separated?

Label:chem

Topic
Benzene is one of the light fraction components produced during the pyrolysis of polystyrene.
Answer
Benzene is a component of the light fraction resulting from polystyrene pyrolysis. It is primarily separated from styrene in the first distillation column along with toluene and ethylbenzene.
