Technology Unit

: Rotating Thermal Kiln reactor
: Alterra Plastics Pyrolysis
Short Name: Rotary Kiln
Description: As highlighted in US10421911B2, the rotating thermal kiln reactor is continuously fed hydrocarbonaceous melt from the extruder through a connecting port. It is heated either electrically or via direct combustion of non-condensable process gas and/or natural gas in two zones, or a combination thereof. Additionally, finely divided, mineral-based additives selected from one or more melt-phase heteroatom scavengers such as oxides, hydroxides and/or carbides of the group consisting of alkali metals, alkaline earth metals, transition metals, post-transition metals and/or metalloids, can be fed at the entrance of the reactor. The reactor comprises a zone for destabilizing and dehalogenating, and a zone for pyrolyzing and for devolatilizing the pyrolyzed hydrocarbonaceous materials, whereby said hydrocarbonaceous materials are converted to vapor products, wherein said vapor products can be further treated to produce condensable and non-condensable products, and solid hydrocarbon products.
