METHOD FOR STARTING UP A PRE-REFORMING STAGE

There is proposed a method for starting up a pre-reforming stage in an integrated reforming plant in which a hydrocarbonaceous feed stream, in particular natural gas, is converted into a reformation product containing carbon oxides, hydrogen and hydrocarbons. Before carrying out the start-up method,...

Summary:There is proposed a method for starting up a pre-reforming stage in an integrated reforming plant in which a hydrocarbonaceous feed stream, in particular natural gas, is converted into a reformation product containing carbon oxides, hydrogen and hydrocarbons. Before carrying out the start-up method, the catalyst contained in the pre-reforming stage is in an oxidized or passivated state. For its activation, the pre-reforming catalyst is charged with a methanol/steam mixture, from which by steam reformation of methanol in situ the hydrogen required for the activation of the catalyst is produced. Excess hydrogen is used for the hydrogen supply of the desulfurization stage arranged upstream of the pre-reforming stage.
