| Abstract: | The HPD- 1 catalyst was made from ZSM - 5 molecular sieve catalyst through special treatment, tne paraffin in diesel oil was catalytic cracked by using the hydrodewaxing catalyst. This resulted in minimized content of the paraffin. The freezing temperature of the oil could consequently downward. A single stage hydrofining - hydrodewaxing in series process was has been applied. Excellent diesel fuel with low freezing temperature has been produced on the experimental plants. The conclusions of various operative conditions have been made. |
