METHOD AND INSTALLATION FOR HEATING AND PARTIAL OXIDATION OF MIXTURE OF STEAM AND NATURAL GAS AFTER THE PRIMARY REFORMER

摘要

1. A method of heating and partial oxidation of an unheated pre-reformed mixture of steam and natural gas for syngas, wherein energy is supplied to the gas stream (raw syngas) in the flow direction after the primary reformer, characterized in that the energy is supplied after the primary reformer directly through at least one porous burner located in the gas outlet channel of the primary reformer. ! 2. A method according to claim 1, characterized in that the energy is supplied through a plurality of porous burners located in the gas outlet channels of the primary reformer forming the flow path. ! 3. A method according to claim 1 or 2, characterized in that, in addition to supplying energy to it by means of a combustible gas and supplying an oxidizing agent, for example oxygen, nitrogen is also supplied to the gas stream in order to make the synthesis gas suitable for use in an ammonia plant. ! 4. The method according to claim 1, characterized in that CO2 and / or steam is additionally supplied to the gas stream. ! 5. A method according to claim 1 or 2, characterized in that the porous burner is used with a pre-reformed mixture of steam and natural gas in a sub-stoichiometric mode or when feeding a combustible gas in a super-stoichiometric mode. ! 6. A method according to claim 1 or 2, characterized in that the gas flow becomes vortex under the influence of a stationary mixer coated with a steam reformer catalyst. ! 7. The method according to claim 1 or 2, characterized in that the gas flow acquires a vortex character under the influence of a stationary mixer placed downstream of the corresponding burner, and the mixer is coated with
