Abstract:
A process for producing an isoparaffinic lubricant base stock which is obtained by (i) hydroisomerizing a waxy, normal paraffinic hydrocarbon fraction having an initial boiling point in the range of 650-750.degree. F. obtained from a Fischer-Tropsch hydrocarbon synthesis process to form a hydroisomerate having an initial boiling point in said 650-750.degree. F. range, (ii) catalytically dewaxing said hydroisomerate by reacting it with hydrogen in the presence of a catalyst comprising a catalytic platinum component and a hydrogen mordenite component to reduce its pour point and form a dewaxate which contains hydrocarbons boiling above and below said 650-750.degree. F. range, and (iii) removing said lower boiling material from said dewaxate to form said base stock.
