摘要：<p>The present invention is directed to a method for hydroprocessing Fischer-Tropsch products. The invention in particular relates to an integrated method for producing liquid fuels from a hydrocarbon stream provided by Fischer-Tropsch synthesis. The method involves separating the Fischer-Tropsch products into a light fraction with normal boiling points below 700°F and including predominantly C5-20 components and a heavy fraction with normal boiling points above 650°F and including predominantly C20+ components. The heavy fraction is subjected to hydrocracking conditions, preferably through multiple catalyst beds, to reduce the chain length. The light fraction is used as all or part of a quench fluid between each catalyst bed.</p>
