Sinopec has been granted an invention patent for “A processing method and processing system for the fluidized cracking of waste plastics”: According to data from the Tianyancha app, Sinopec (600028) has obtained a new invention patent, titled “A processing method and processing system for the fluidized cracking of waste plastics”. The patent application number is CN202211057426.1, and the date of grant is August 12, 2025. Patent Abstract: This disclosure relates to a processing method and processing system for the fluidized cracking of waste plastics. The method comprises the following steps: S1. Feeding the waste plastics to be treated into a waste plastic liquefaction unit for liquefaction, thereby obtaining liquefied waste plastics ； S2: Feed the liquefied waste plastic into the waste plastic viscosity-reduction unit for viscosity-reduction cracking treatment, to obtain oil derived from the liquefied waste plastic after such treatment and first dry gas ； S3: The viscosity-reduced, cracked liquefied plastic oil is fed into the contact cracking reaction unit, where it comes into contact with a fluidized catalyst to undergo cracking, resulting in reaction gas oil and raw catalyst ； S4: The reaction gas oil is fed into a separation unit for separation, yielding second dry gas, liquefied gas, gasoline fractions, diesel fractions, and wax oil fractions. This disclosure achieves the resource utilization of waste plastics.
