Abstract
A dewaxing catalyst is selectively activated by treatment with an oxygenate. Selective activation is accomplished by treated the dewaxing catalyst with a carrier feed containing oxygenate. The selectively activated dewaxing catalyst when used to dewax waxy hydrocarbons results in improved yield of isomerate at equivalent pour point over a dewaxing catalyst which has not been oxygenate treated.
