Abstract
A method for treating a porous crystalline catalyst optionally associated with a metal component such as a noble and/or base metal(s) is described. The method comprises contacting the catalyst with a low molecular weight aromatic compound under coking conditions. Such a treatment method increases the cycle length and the useful life of the catalyst. Using the treated catalyst in a dewaxing process and regenerating the catalyst by treating with hydrogen and a low molecular weight hydrocarbon.
