Title:
PRODUCTION OF LUBRICATION BASE OIL
Document Type and Number:
Japanese Patent JP2521873
Kind Code:
B2
Abstract:
PURPOSE: To carry out the production of a hydro-refined general-purpose lubrication base oil and a lubrication base oil having a high viscosity index in single reactor in contrast with conventional process to use separate reactors containing different catalysts and to produce the lubrication base oils without causing the lowering of the catalytic activity over a long period.
CONSTITUTION: A general-purpose lubrication base oil and a lubrication base oil having a high viscosity index are produced in single reactor by using a catalyst obtained by selecting at least one kind of metal component from the group VIA and group VIII elements of the 4th period of the periodic table as an essential component and supporting the component on a refractory oxide carrier, especially a catalyst obtained by supporting molybdenum, nickel and phosphorus on alumina carrier and alternately carrying out the hydro-refining of a production intermediate for sulfur-containing lubrication base oil and the isomerization of a wax.
