  • Patent number: 12285749
    Abstract: The present invention relates to an adiabatic, zoned reactor for the reforming of NH3 to N2 and H2, the reactor particularly comprising n reaction zones arranged in sequence and extending along the axial length L of the reactor, wherein n is an integer in the range of from 2 to 5, wherein independently from one another, each of the n reaction zones comprises one or more catalytic components, wherein from the inlet reaction zone to the outlet reaction zone each reaction zone displays a lower light-off temperature T50 in the reforming of NH3 to N2 and H2 then the subsequent downstream one. Further, the present invention relates to a production unit comprising said reactor, a process for the reforming of NH3 to N2 and H2, and use of said reactor and said production unit.

  • Publication number: 20250002796
    Abstract: The present invention relates to a process for purifying a pyrolysis oil comprising providing a stream S0 comprising a pyrolysis oil, the pyrolysis oil comprising one or more halogenated organic compounds and one or more organic compounds comprising conjugated double bonds; subjecting the stream S0 to hydrogenation in at least one reaction zone Z1 containing a heterogeneous hydrogenation catalyst, obtaining a stream S1 being depleted, compared to S0, in the one or more organic compounds comprising conjugated double bonds; subjecting the stream S1 to dehalogenation in at least one dehalogenation zone Z2 down-stream of Z1, obtaining a stream S2 being depleted, compared to S1, in the one or more halogenated organic compounds.
