费托合成
摘要：
一种合成费托产物(20)的方法(10)，包括将合成气(30)进料至在移动催化剂床中包含费托催化剂的移动床费托合成反应器(16)，将移动催化剂床中的至少一部分合成气(30)催化转化成费托产物(20)。从所述移动床费托合成反应器(16)取出所述费托产物(20)。该方法(10)进一步包括，当移动床费托合成反应器(16)在线时，从移动床费托合成反应器(16)取出一部分费托催化剂(50)，向移动床费托合成反应器(16)加入再活化的费托催化剂(57，58)，并且除加入所述再活化的费托催化剂(57，58)外，还向移动床费托合成反应器(16)加入新鲜的费托催化剂(60，58)。
摘要（英）：

A method (10) of synthesising Fischer-Tropsch products (20) includes feeding a synthesis gas (30) to a moving-bed Fischer-Tropsch synthesis reactor (16) containing a Fischer-Tropsch catalyst in a moving catalyst bed and catalytically converting at least a portion of the synthesis gas (30) in the moving catalyst bed to Fischer-Tropsch products (20). The Fischer-Tropsch products (20) are removed from the moving-bed Fischer- Tropsch synthesis reactor (16). The method (10) further includes, while the moving-bed Fisher-Tropsch synthesis reactor (16) is on-line, withdrawing a portion (50) of the Fischer-Tropsch catalyst from the moving-bed Fischer-Tropsch synthesis reactor (16), adding a reactivated Fischer-Tropsch catalyst (57, 58) to the moving-bed Fischer-Tropsch synthesis reactor (16), and adding a fresh Fischer-Tropsch catalyst (60,58), in addition to the reactivated catalyst (57,58), to the moving-bed Fischer-Tropsch synthesis reactor (16).
