Lubricating base oil manufacturing plant for producing base oils having desired cycloparafinic functionality

A lubricating base oil manufacturing plant, comprising:

• (a) a Fischer-Tropsch synthesis plant which comprises a Fischer-Tropsch derived wax having:
• I. a weight ratio of compounds having at least 60 or more carbon atoms and compounds having at least 30 carbon atoms less than 0.18;
• II. greater than about 75 mass percent normal paraffin;
• and
• III. a difference between the T90 and T10 boiling points of at least 171° F. (95° C.);
• (b) a hydroisomerization reactor comprising a catalyst comprising a shape selective intermediate pore size molecular sieve which is operated at a hydrogen to feed ratio from about at 712.4 to about 3562 liter H2/liter feed (about 4 to about 20 MSCF/bbl);
• wherein the hydroisomerization reactor is configured to receive said Fischer-Tropsch wax from the synthesis plant;
• and
• (c) a reactor comprising a hydrofinishing catalyst which is configured to receive the hydroisomerized Fischer-Tropsch derived wax;
• wherein the base oil manufacturing plant comprises one or more lubricating base oils produced from the Fischer-Tropsch wax having:
• I. greater than 10 weight percent total molecules with cycloparaffinic functionality, and
• II. less than 0.5 weight percent of molecules with multicycloparaffinic functionality.
