A method () of synthesizing Fischer-Tropsch products () includes feeding a synthesis gas () to a moving-bed Fischer-Tropsch synthesis reactor () containing a Fischer-Tropsch catalyst in a moving catalyst bed and catalytically converting at least a portion of the synthesis gas () in the moving catalyst bed to Fischer-Tropsch products (). The Fischer-Tropsch products () are removed from the moving-bed Fischer-Tropsch synthesis reactor (). The method () further includes, while the moving-bed Fisher-Tropsch synthesis reactor () is on-line, withdrawing a portion () of the Fischer-Tropsch catalyst from the moving-bed Fischer-Tropsch synthesis reactor (), adding a reactivated Fischer-Tropsch catalyst () to the moving-bed Fischer-Tropsch synthesis reactor (), and adding a fresh Fischer-Tropsch catalyst (), in addition to the reactivated catalyst (), to the moving-bed Fischer-Tropsch synthesis reactor ().
