Title:
向上されたZSM-5触媒を用いる高粘度潤滑油基材油の製造
Document Type and Number:
Japanese Patent JP4820519
Kind Code:
B2
Abstract:
The present invention is a process for producing a high viscosity index and low pour point lubricating oil base stock which comprises catalytically converting a hydrotreated hydrocarbon lube oil feedstock containing waxy paraffins in the presence of hydrogen and in the presence of a low acidity ZSM-5 catalyst having a highly dispersed noble metal component. The ZSM-5 catalyst is subjected to controlled acidity reduction to an alpha value below 15 prior to incorporation of the noble metal component.
