1. 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.
