Document Type and Number:
WIPO Patent Application WO/2013/147190
Kind Code:
A1
Abstract:
Provided is a method for dewaxing hydrocarbon oils that increases the life of hydroisomerization catalysts. An embodiment of this method for dewaxing a hydrocarbon oil comprises: a first step of obtaining an object to be treated having a peroxide value of 30 mass ppm or less by subjecting a hydrocarbon oil having a peroxide value of 100 mass ppm or greater to a hydrogenation treatment; and a second step of subjecting the object to be treated, which has a peroxide value of 30 mass ppm or less, to a hydroisomerization treatment using a hydroisomerization catalyst.
