ABSTRACT:
Process for the continuous catalytic dewaxing of lube containing feeds wherein the feed effectively moves countercurrently to the catalyst. The process is based on the discovery that in a two-stage catalytic dewaxing process the stage-two or back-end dewaxing catalyst shows a concave upward aging when it is used to produce a targeted pour point lube, but the back-end dewaxing catalyst can be used as a stage one or front-end dewaxing catalyst to produce an intermediate pour point product.
