Abstract: Systems and processes for pyrolyzing waste plastics, including, in one or more heating stages, heating a waste plastic from an initial temperature to a peak pyrolysis temperature, and, in a final pyrolysis stage, providing heat input sufficient to maintain a temperature of the waste plastic at a pyrolysis reaction temperature less than the peak pyrolysis temperature and maintaining the waste plastic at the pyrolysis reaction temperature for a time period to convert a portion of the waste plastic to a pyrolyzed product and a pitch. The process further includes recovering the pyrolyzed product and recovering the pitch.

Abstract: Process and systems for converting waste plastics include feeding a waste plastic to a melt tank, and in the melt tank, heating the waste plastic to form a molten plastic. The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor. In the pyrolysis reactor, the molten plastic is heated to a pyrolysis temperature, producing a pyrolysis oil product and a liquid pitch product. The pyrolysis oil is then separated into a pyrolysis gas fraction, a light pyrolysis oil fraction, a medium pyrolysis oil fraction, and a heavy pyrolysis oil fraction.

Abstract: An electrically heated furnace including one or more unit cells. Each unit cell includes a radiant heating section, one or more process coils disposed within the radiant heating section, and a quench unit for cooling a cracked product from the one or more process coils and producing a quenched reaction product. The furnace also includes one or more electrical heating elements disposed within the radiant heating section, the one or more electrical heating elements are arranged to provide radiant energy to the one or more process coils. Further, the electrically heated furnace includes a first area corresponding to a heating area of the one or more electrical heating elements, a second area corresponding to a wall area of the wall on which the one or more electrical heating elements are disposed, and a third area corresponding to a surface area of the one or more process coils.
