摘要

Waxy hydrocarbon feedstocks are contacted with a hydrocracking catalyst and the effluent then contacted with an intermediate pore size molecular sieve hydroisomerization catalyst. The effluent from the hydroisomerization is fractionated to provide a heavy fraction and a middle distillate fuel. A high quality lubricant base oil with a high viscosity index and a low pour point is isolated from the heavy fraction.
