Abstract[English]
A method of starting up a Fischer-Tropsch plant for synthesizing hydrocarbon products, the method comprising: heating an activation gas; and passing the heated activation gas over a Fisher-Tropsch catalyst within a Fisher-Tropsch reactor to reduce and activate the Fisher-Tropsch catalyst in-situ within the Fisher-Tropsch reactor of the Fischer-Tropsch plant, wherein the heating of the activation gas comprises heating the activation gas to a first temperature in a range 200°C to 260°C using a steam heater and then boosting the temperature of the activation gas to a second temperature in a range 270°C to 350°C using an electric booster heater.[French]
L'invention concerne un procédé de démarrage d'une installation Fischer-Tropsch de synthèse de produits hydrocarbonés. Ledit procédé comprend : le chauffage d'un gaz d'activation ; et le passage du gaz d'activation chauffé sur un catalyseur de Fisher-Tropsch à l'intérieur d'un réacteur de Fisher-Tropsch pour réduire et activer le catalyseur de Fisher-Tropsch in situ à l'intérieur du réacteur de Fisher-Tropsch de l'installation Fischer-Tropsch. Le chauffage du gaz d'activation comprend le chauffage du gaz d'activation à une première température dans une plage de 200°C à 260°C à l'aide d'un dispositif de chauffage à vapeur et ensuite l'amplification de la température du gaz d'activation à une seconde température dans une plage de 270°C à 350°C à l'aide d'un dispositif de chauffage de survolteur électrique.
