Abstract
The invention is a hydrocracking process which produces an increased amount of hydrocarbons useable as diesel fuel by isomerization of high boiling paraffins using a dewaxing catalyst. The process is characterized by the use of a dewaxing catalyst containing a very small amount of a non-noble metal hydrogenation component such as nickel on an intermediate pore nonzeolitic molecular sieve (NZMS) material. This dewaxing catalyst has been found to be very effective in reducing the pour point of a diesel boiling range distillates even in the presence of sulfur levels which adversely affect catalysts containing higher amounts of the same metal component.
