1. A method for producing hydrocarbons from plastic containing material, wherein the method comprises:
subjecting the plastic containing material into a fluidized bed pyrolysis reactor;
feeding steam, used at least in part as a fluidizing gas, into the fluidized bed pyrolysis reactor; and
pyrolyzing the plastic containing material with the steam at a residence time of 0.5-3.0 seconds by using a catalytic pyrolysis with a basic catalyst to convert the plastic containing material to a product comprising hydrocarbons, wherein the basic catalyst is selected from the group consisting of dolomite and limestone; and
wherein the product comprising hydrocarbons is a liquid hydrocarbon product and a yield of hydrocarbon liquid is higher than a yield of hydrocarbon wax.
