Embodiments of a method for producing a diesel range material having improved cold flow properties are provided. In one embodiment, the method includes the steps of providing a waxy diesel range feedstock, producing an intermediary product stream containing a predetermined amount of oxygenated organocompounds from the waxy diesel range feedstock, and contacting the intermediary product stream with a dewaxing catalyst under process conditions at which the oxygenated organocompounds chemically interact with the dewaxing catalyst to convert a portion of the n-paraffins within the intermediary product stream to iso-paraffins while minimizing cracking of the diesel range material. |
