A system for continuously treating recycled polymeric material includes a hopper configured to feed the recycled polymeric material into the system. An extruder can turn the recycled polymeric material in a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. The molten material is depolymerized in a reactor. In some embodiments, a catalyst is used to aid in depolymerizing the material. In certain embodiments, the catalyst is contained in a permeable container. The depolymerized molten material can then be cooled via a heat exchanger. In some embodiments, multiple reactors are used. In certain embodiments, these reactors are connected in series. In some embodiments, the reactor(s) contain removable static mixer(s) and/or removable annular inserts.

Systems and methods are provided for processing a feed derived from a renewable source to form oligomerized compounds corresponding to waxes, ketone waxes, and/or lubricant boiling range compounds. The oligomerized compounds derived from the renewable source can have various novel properties relative to waxes and/or lubricant boiling range compounds derived from mineral sources or derived from renewable sources in a conventional manner. The oligomerized compounds can be derived from a renewable source including fatty acids and/or fatty acid derivatives, such as glycerides (including triglycerides) and fatty amides. Optionally but preferably, at least a portion of the fatty acids and/or fatty acid derivatives can include olefinic bonds.
