Definitions
- the invention relates to a method for starting up a catalyst and a reactor and to an apparatus for carrying out the method.
- the object of the present invention is to design a method of the type mentioned in the introduction and a device for carrying out the method such that process water containing chloride and thus the corrosion of the system is avoided or minimized.
- this object is achieved in that at least one oxidation and reduction cycle of the catalyst is passed through after the filling and before the startup of the reactor.
- the basic idea of the invention is to liberate the chloride contained in the catalyst before the reactor is put into operation, without the chloride getting into the process water and causing corrosion.
- the catalyst is subjected to at least one oxidation phase and one reduction phase in a plant for dehydrogenation of hydrocarbon-containing feedstock.
- air and / or steam are used as the oxidizing agent and gaseous hydrogen and / or steam as the reducing agent.
- the resulting chloride-containing exhaust gas is advantageously discharged into the atmosphere.
- this object is achieved in that the device has at least one feed for the reactants (oxidizing agent and reducing agent) and a discharge for the gaseous reaction product (chloride-containing gas) in the atmosphere.
- Fresh catalyst 0.23% total weight
