Abstract

An improved method which provides for an extended cycle length in catalytic lube dewaxing and easier catalyst regeneration. The method may incorporate catalytically dewaxing a feedstock in a fixed bed reactor with or without product recycle, or a series of reactors with inter-reactor separation of vapors from liquids. Improved performance is achieved by operating the reactor at a temperature between 260 to 316 DEG C (500 to 600 DEG F), a space velocity between 0.1 and 10 and employing a high activity crystalline zeolite catalyst having an alpha value from 50 to 900 based on the zeolite. This relatively low temperature operation allows catalyst performance to be restored by simple hydrogen reactivation.
