Abstract (en)
[origin: WO2004067165A1] The invention relates to a multi-zone tubular reactor (2; 60; 90; 130) for carrying out exothermic gas-phase reactions. Said reactor comprises at least one reaction zone (I) that operates with evaporation cooling, at least one reaction zone (II) that operates with circulation cooling and optionally additional zones (III, IV). The reactor is characterised in that a reaction zone (I) that operates with evaporation cooling constitutes the first reaction zone and that an additional reaction zone (II) that operates with evaporation cooling or with circulation cooling adjoins said first zone. This permits intensive cooling at the start of the reaction, where the latter is at its most violent stage, at a temperature that can be precisely controlled and is constant over the entire reactor cross-section, whilst achieving a subsequent cooling of the reaction gas in a post-reaction zone that operates with circulation cooling, by means of a global counter-flow of the heat-transfer medium.
