摘要
A process for producing one or more white oils, by: a) hydroisomerization dewaxing a waxy feed with a defined composition over a highly selective and active wax hydroisomerization catalyst with a defined composition under conditions sufficient to produce a white oil; and b) collecting one or more white oils, wherein the yield of white oils is high, and they have a low pour point and a good Saybolt color. Also, a process for producing medicinal grade white oils, by a)hydroisomerization dewaxing a waxy feed with a defined composition over a highly selective and active wax hydroisomerization catalyst with a defined composition under conditions sufficient to produce a white oil, b) collecting technical grade white oils having a low pour point and good Saybolt color in high yield, and c) hydrofinishing the technical grade white oils at conditions sufficient to produce medicinal grade white oils that pass the RCS test.
