Abstract
A method for forming catalytically treated pyrolytic vapor product from pyrolyzable material, the method comprising burning fuel in a fluidized bed boiler, thereby heating some particulate material; transferring at least some of the heated particulate material or some other heated particulate material to a pyrolysis reactor to pyrolyze some pyrolyzable material in the pyrolysis reactor; and conveying at least some pyrolytic vapor through a catalyst bed comprising catalyst material; and conveying at least part of the formed side products upstream back to the process; thereby producing the catalytically treated pyrolytic vapor product in an resource efficient manner. In addition, a system configured to produce catalytically treated pyrolytic vapor product from pyrolyzable material. The system comprises a fluidized bed boiler; a pyrolysis reactor; a catalytic reactor; means for conveying some heated particulate material to the pyrolysis reactor; a pipeline for conveying at least some pyrolytic vapor from the pyrolysis reactor into the catalytic reactor and means for conveying at least part of the formed side products upstream back to the process for recovering heat and chemical energy bound to the side products.
