A process for converting pyrolysis effluent stream into hydrocarbon products. Waste plastics are pyrolyzed at high temperature in a pyrolysis reactor to obtain a plastic pyrolysis effluent stream. The plastic pyrolysis effluent stream is further sent to a steam cracking unit for the separation of plastic pyrolysis effluent stream into a C5+ hydrocarbon stream and a C4 hydrocarbon stream. The pyrolysis reactor is operated at a to obtain hydrocarbon products of high value.

Integrated process for pyrolysis and steam cracking

Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is separated for forming an H-rich stream and a first liquid phase hydrocarbon stream. The H-rich stream may be contacted with an adsorbent to form an H-ultra rich stream and a gas stream. C/Chydrocarbons are absorbed from the gas stream with the liquid phase hydrocarbon stream. The gas stream may be contacted with an H/hydrocarbon separation membrane to separate the PSA tail gas stream and form an H-rich permeate stream and an Hdepleted non-permeate residue stream.
