Abstract

A method and reactor assembly for pyrolysis-based production of hydrocarbon oils from a first plastic raw material, comprising optionally combining the plastic raw material with a second raw material selected from the group consisting of a hydrocarbon containing raw material selected among crumb rubber and wood chunks in an amount constituting more than 15% by weight of the combined raw material adding a catalyst to the combined raw materials to thereby form a reaction composition, charging the reaction composition through an airlock valve to an auger pyrolysis reactor comprising at least two auger reactors heated to a temperature in the range 450-550° C., diverting oil vapours and non-condensable vapours from the auger reactors to a condensing device, condensing in two steps a heavy oil fraction and a light oil fraction from said vapours.
