Abstract: The present invention relates to a method for producing at least one purified pyrolysis oil fraction from a hydrocarbon based waste plastic comprising polyolefins and heteroatom-based contaminants, which method comprises the steps of: Step 1) pyrolyzing the hydrocarbon based waste plastic to produce a gaseous pyrolysis product comprising at least saturated hydrocarbons, unsaturated hydrocarbons, and contaminants including heterogenates; Step 2) at least partially condensing the gaseous pyrolysis product to produce at least one liquid pyrolysis oil fraction; and Step 3) purifying the at least one liquid pyrolysis oil fraction by removing at least a portion of the heterogenates contained therein by a liquid extraction process and/or a liquid-solid adsorption process and/or a precipitation process to produce at least one purified pyrolysis oil fraction.
