<p>A process for activating a cobalt-containing catalyst by contacting the catalyst with hydrogen in a reaction system suitable for use in a Fischer-Tropsch synthesis wherein a first gaseous stream comprising 0.25 to 5 % by volume of hydrogen and 95 to 99.75 % by volume of inert gas is continuously introduced into the reaction system and a second gaseous stream is continuously withdrawn from the reactor system wherein the activation procedure comprises the steps of: (A) heating the contents of the reactor system to a temperature which is in a range of 25 to 5 °C below a critical activation temperature; (B) thereafter increasing the temperature at a rate of up to 20 °C per hour to a first hold temperature which is in a range of from the critical activation temperature to a temperature which is at most 20 °C above the critical activation temperature; and (C) maintaining the contents of the reactor system approaches the hydrogen content of the first gaseous stream.</p> |
