Abstract
Systems and methods for processing a mixed plastic waste feed to produce a hydrogen-rich hydrocarbon product, such as synthetic crude oil or pyrolysis oil, by processing the mixed plastic waste feed through two cracking units. The first cracking unit is operated at a temperature and a residence time sufficient to at least partially depolymerize the plastic polymers in the mixed plastic waste feed to produce a molten oligomers product stream also containing inorganic components from the mixed plastic waste feed and a gas stream. This molten oligomers product stream is further processed in a thermal or a catalytic cracking unit to produce a hydrocarbonaceous stream that is processed to produce the hydrogen-rich hydrocarbon product, such as a synthetic crude oil that can be processed in a refinery or a pyrolysis oil that can be fed to a steam cracker.
