Possesses the light cut which is the cut which contains the component of 5-20

摘要

The present invention, Fischer - directed to a method for hydrotreating Tropsch product. In particular, the present invention is the Fischer - relates integrated process for producing liquid fuels from a hydrocarbon stream obtained by Tropsch synthesis. Fisher method, - normal boiling point is 700 ° F less than Tropsch products, and light fraction containing the components of the ₅ ~ ₂₀ C primarily, normal boiling point is higher than 650 ° F, the ₂₀ + C primarily It includes separating into a heavy fraction containing components. Preferably being provided via the plurality of catalyst beds, the hydrocracking conditions, heavy fraction, to reduce the chain length. The light fraction is used as part or all of the quench fluid in the catalyst bed to another.
