    摘要： The invention relates to a method and an apparatus for removing impurities from a gasification gas, wherein the gasification gas which includes at least tars and/or undesired hydrocarbons is supplied to a catalytic reformer which has at least one catalyst bed, oxygen containing gas is injected onto the surface of the catalyst bed, the gasification gas is arranged to flow through the catalyst bed and arranged to contact with the oxygen containing gas in the catalyst bed, and a purified gas is discharged from the catalytic reformer. Further, the invention relates to the use of the method.

    摘要： 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.

    摘要： The invention relates to a chemical reactor and reformer tubes for reforming a first feed stream comprising a hydrocarbon gas and steam. The chemical reactor comprises a shell with a heat source and one or more reformer tubes. The reformer tube is arranged to house catalyst material and is arranged to being heated by the heat source. The reformer tube comprises a first inlet for feeding said first feed stream into a first reforming reaction zone of the reformer tube, and a feed conduct arranged to allow a second feed stream into a second reforming reaction zone of the reformer tube. The second reforming reaction zone is positioned downstream of the first reforming reaction zone. The feed conduct is configured so that the second feed stream is only in contact with catalyst material in the second reforming reaction zone. The invention also relates to a process of producing CO rich synthesis gas at low S/C conditions.
