Abstract
A method for the operation of a hydrodewaxing unit wherein a petroleum distillate is separated into two streams, one having a pour point of above about 30.degree.F, and the other having a pour point of less than about 30.degree.F., the 30.degree.F plus pour point fraction is treated in a hydrodewaxing unit with a ZSM-5 type catalyst under hydroprocessing conditions while the 30.degree.F. minus pour point portion is untreated and combined with the hydrodewaxed product. The process yields a net production of hydrogen, and exhibits excellent catalyst aging characteristics.
