Document Type and Number:
Japanese Patent JP2005527672
Kind Code:
A
Abstract:
Provided is a continuous process for converting waste or virgin plastics into lube oils. The plastic feed is maintained in a heater at preferred temperatures of 150° C.-350° C. The feed is continuously passed to a pyrolysis reactor preferably maintained at a temperature of 450° C.-700° C. and at atmospheric pressure. Relatively short residence times are employed. Optionally, the reactor effluent is processed in a hydrotreating unit. The effluent is fed to an isomerization dewaxing unit and fractionated to recover lube oil stocks. Preferably, the feed to the pyrolysis reactor can be a blend of waste plastic and waxy Fischer-Tropsch fractions.
