Abstract

Described herein are pyrolysis systems and pyrolysis processes for achieving a lighter yield slate than provided in conventional pyrolysis systems. Aspects include: recycling a gaseous pyrolysis product into the pyrolysis reactor to enhance the mixing of the pyrolysis system reactants; installing a bottoms liquid recycle stream to better mix the pyrolysis system reactants; and/or recycling at least a portion of a heavy fraction of the gaseous pyrolysis reactor effluent from a condenser system into the pyrolysis reactor liquid. These improvements can enhance the economic viability of plastic wastes to liquid and gaseous hydrocarbon products which are used for making circular chemical and polymer products.
