PROCESS FOR PRODUCTION OF HYDROCARBON COMPOSITION, HYDROCARBON COMPOSITION, LUBE BASE OIL AND LUBRICATING OIL COMPOSITION

Title:

PROCESS FOR PRODUCTION OF HYDROCARBON COMPOSITION, HYDROCARBON COMPOSITION, LUBE BASE OIL AND LUBRICATING OIL COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2010/041590

Kind Code:

A1

Abstract:

Provided is a process for production of a hydrocarbon composition. In the process, urea is brought into contact with a hydrocarbon raw material comprising branched paraffins which each bear an alkyl group branch having five or less carbon atoms, whereby, among the branched paraffins, branched paraffins each having six or more carbon atoms between at least one end and the branch position are separated from the hydrocarbon raw material in the form of urea adducts. Thus, an objective hydrocarbon composition is obtained. The composition exhibits a high viscosity index and excellent low-temperature characteristics and is particularly suitable for use as a lube base oil or a lubricating oil composition.
