SUPPORTED NI-CU HYDROCONVERSION CATALYST

摘要

Nickel-copper catalysts supported on an acidic carrier, preferably containin g a binder, are used to hydroisomerize paraffins, particularly Fischer-Tropsch paraffins, boiling at 350 .degree.F+ into lighter, more valuable products. The hydroisomerization process involves introducing the paraffin-containing feed (39) into a fractionator (40) where it is separated into a 350 .degree.F- lighter fraction and a 350 .degree.F+ heavie r fraction. The lighter fraction is hydrotreated in hydrotreater (44) and the heavier fraction is hydroisomerized using the nickel-copper catalysts in reactor (54), whereafter the effluents from hydrotreater (44) and reactor (5 4) are combined to produce a product stream.
