    摘要： A process for manufacturing a lubricating base oil by: a) performing Fischer-Tropsch synthesis on syngas to provide a product stream; b) isolating from said product stream a substantially paraffinic wax feed having less than about 30 ppm total nitrogen and sulfur, and less than about 1 wt % oxygen; c) dewaxing said feed by hydroisomerization dewaxing using a shape selective intermediate pore size molecular sieve comprising a noble metal hydrogenation component, wherein the hydroisomerization temperature is between about 600° F. (315° C.) and about 750° F. (399° C.), to produce an is dimerized oil; and d) hydrofinishing said isomerized oil to produce a lubricating base oil having specific desired properties.
