Title:
METHOD FOR CONVERTING WASTE PLASTIC INTO LUBRICATING OIL
Document Type and Number:
Japanese Patent JP2010121140
Kind Code:
A
Abstract:

To provide a continuous method for converting waste/virgin plastics into lubricating oils.

A plastic feed is maintained inside a heater (930) preferably at 150-350C. The feed is continuously supplied to a pyrolysis reactor (30) preferably maintained at 450-700C and at the atmospheric pressure. Relatively short residence times are employed. Optionally, a reactor effluent is processed in a hydrotreating unit (40). The effluent is fed to an isomerization dewaxing unit (50) and fractionated (50) to recover lubricating oil stocks. Preferably, the feed to the pyrolysis reactor can be a blend of waste plastic and waxy Fischer-Tropsch fractions.
