PROCESS FOR THE ACTIVATION OF A CATALYST

摘要

A Fischer-Tropsch catalyst is activated by a process comprising reducing the catalyst by contact with a hydrogen- containing gas, the hydrogen concentration and the space velocity of the gas contacting the catalyst increasing step-wise or continuously during the activation. The process may be employed to activate a fresh catalyst prior to its use or to regenerate an exhausted or partially exhausted catalyst. The catalyst, once activated, may be used in a process for the preparation of hydrocarbons from carbon monoxide and hydrogen.
