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.

The process of claim 1 wherein the oxygenate is at least one alcohol, carboxylic acid, ester, aldehyde, ketone or ether. 3. The process of claim 1 wherein the oxygenate is water. 4. The process of claim 1 wherein the carrier feed is the wax containing hydrocarbon feed. 5. The process of claim 1 wherein the dewaxing catalyst is sulfided, reduced, or sulfided and reduced. 6.

The process of claim 11 wherein the carrier feed is the wax containing hydrocarbon feed. 15. The process of claim 13 wherein the dewaxing catalyst is sulfided, reduced, or sulfided and reduced. 16. A process for selectively activating a ZSM-48 catalyst for the catalytic dewaxing of a wax containing hydrocarbon feed which comprises: contacting ZSM-48 in the hydrogen form on an alumina or alumina-containing binder with a carrier feed containing at least about 100 wppm to 10,000 wppm, measured as oxygen, of an oxygenate which is at least one alcohol, carboxylic acid, ester, aldehye, ketone or ether at a temperature of from 120 to 400째 C. and a hydrogen pressure of from 101 to 20786 kPa, provided that the mode of dewaxing is by isomerizing waxy molecules and the selectivity of the ZSM-48 catalyst is improved by isomerizing at least 4 relative % more of the wax into lube isomerate. 17. The process of claim 16 wherein the carrier feed is the wax containing hydrocarbon feed. 18. The process of claim 16 wherein the ZSM-48catalyst is sulfided, reduced, or sulfided and reduced. 19. The process of claim 16 wherein the ZSM-48catalyst bears a metal hydrogenation component. 20. The process of claim 19 wherein the metal hydrogenation component is at least one Group 9 or 10 noble metal. 21. A process for selectively activating a dewaxing catalyst for the catalytic dewaxing of a wax containing hydrocarbon feed which comprises: contacting the dewaxing catalyst which is ZSM-48 in the hydrogen form on an alumina or alumina-containing binder with a carrier feed containing at least about 100 wppm to 10,000 wppm, measured as oxygen of an oxygenate which is water at a temperature of from 120 to 400째 C. and a hydrogen pressure of from 101 to 20786 kPa, provided that the mode of dewaxing is by isomerizing waxy molecules and the selectivity of the dewaxing catalyst is improved by isomerizing at least 4 relative % more of wax component into lube isomerate.
