<p>The process takes place in a reaction zone (1) containing a synthesis gas and a catalyst in a fluidized bed with a three-phase fluidization sequence, with a coolant fluid circulated through at least one internal heat exchange zone (2). The coolant fluid, selected from ethanol, methanol or a mixture of these, is fed into the heat exchange zone at a temperature close to its boiling point at the pressure of the reaction medium, i.e. 10-70degreesC, preferably 15-60degreesC, below the temperature of the reaction medium. The pressure of the reaction medium is 30-50 bars, and its temperature is 220-240degreesC.</p> |
