Definitions
- the present invention relates to a process for the production of chlorine by catalytic gas-phase oxidation of hydrogen chloride with oxygen, wherein the reaction is carried out on at least two catalyst beds under adiabatic conditions, and a reactor system for carrying out the process.
- the catalyst is used in the form of a fluidized, thermally stabilized bed.
- the catalyst bed is tempered via the outer wall, and according to DE 10 2004 006 610 A1, the fluidized bed is tempered via a heat exchanger arranged in the bed.
- the effective heat removal of this process faces problems of non-uniform residence time distribution and catalyst wear, both of which result in a loss of revenue.
- a narrow residence time distribution and low catalyst abrasion are possible in reactors with stationary catalyst beds.
- problems arise in such reactors with the thermostating of the catalyst beds.
- thermostated tube bundle reactors are used which, especially in the case of large reactors, have a very complicated cooling circuit (WO 2004/052776 A1).
- the catalysts used initially for the Deacon process for example supported catalysts with the active material CuC12, had only a low activity. Although the activity could be increased by increasing the reaction temperature, it was disadvantageous that the volatility of the active components at high temperature led to rapid deactivation of the catalyst.
- the oxidation of hydrogen chloride to chlorine is also an equilibrium reaction. The position of the equilibrium shifts with increasing temperature to the detriment of the desired end product.
- catalysts with the highest possible activity are used, which allow the reaction to proceed at low temperature.
- Known highly active catalysts are based on ruthenium.
- DE-A 197 48 299 describes supported catalysts with the active material ruthenium oxide or ruthenium mixed oxide.
- the content of ruthenium oxide is 0.1 wt .-% to 20 wt .-% and the average particle diameter of ruthenium oxide 1.0 nm to 10.0 nm.
- the reaction is carried out at a temperature between 90 0 C and 150 0 C.
- ruthenium chloride catalysts containing at least one compound of titanium oxide or zirconium oxide, ruthenium-carbonyl complexes, ruthenium salts of inorganic acids, ruthenium-nitosyl complexes, ruthenium-amine complexes , Ruthenium complexes of organic amines or ruthenium-acetylacetonate complexes.
- the reaction is carried out at a temperature between 100 0 C and 500 0 C, preferably 200 0 C and 380 0 C.
- the catalyst is used in a fixed bed or in a fluidized bed.
- the oxygen source used is air or pure oxygen.
- the Deacon reaction remains an exothermic reaction and temperature control is also required in the application of such highly active catalysts.
- the present invention therefore relates to a process for the preparation of chlorine by catalytic gas-phase oxidation of hydrogen chloride with oxygen, characterized in that the reaction is carried out on at least two catalyst beds under adiabatic conditions.
- the reaction is preferably carried out on at least two catalyst beds connected in series.
- the process gas may in addition to oxygen and hydrogen chloride still have minor components, eg. As nitrogen, carbon dioxide, carbon monoxide or water.
- the hydrogen chloride can upstream production process, eg. As for the production of polyisocyanates, originate and other impurities, eg. B. phosgene.
- carrying out the process under adiabatic conditions on the catalyst beds means that substantially no heat is supplied to the catalyst from the outside in the respective catalyst beds, nor is heat removed (with the exception of the heat which is supplied or removed by the reaction gas entering or leaving). , Technically, this is achieved by insulating the catalyst beds in a conventional manner.
- Essential to the invention is that the individual catalyst beds are operated adiabatically, so in particular no means of heat dissipation are provided in them.
- the invention also includes the case in which the heat of reaction is removed, for example, by means of heat exchangers connected between the individual catalyst beds.
- catalyst bed is here an arrangement of the catalyst in all known forms, e.g. Fixed bed, fluidized bed or fluidized bed understood. Preferred is a fixed bed arrangement.
