Abstract
The invention relates to a method and an apparatus for producing a hydrocarbons product from plastic containing material, wherein the plastic containing material is subjected into a pyrolysis reactor, steam is fed into the pyrolysis reactor, and the plastic containing material is pyrolyzed in the presence of the steam by using a catalytic pyrolysis with a mildly acidic catalyst comprising at least aluminium oxide, aluminium silicate, zirconium oxide or their combinations to convert the plastic containing material to the hydrocarbon product comprising wax. Further, the invention relates to the use of the product obtained by the method.
Claims11
A method for producing a hydrocarbon product from plastic containing material, wherein the method comprises steps:
- subjecting the plastic containing material into a pyrolysis reactor,
- feeding steam into the pyrolysis reactor, and
- pyrolyzing the plastic containing material in the presence of the steam by using a catalytic pyrolysis with a mildly acidic catalyst which contains Al2O3 to convert the plastic containing material to the hydrocarbon product comprising wax, wherein the hydrocarbon product comprises 40-90 wt-% wax, and residence time is 0.5-3.0 seconds in the catalytic pyrolysis.
