Abstract
This invention relates to a method for catalytically manufacturing a low pour point petroleum product from distillates of crude oil, and more particularly to a method for economically manufacturing a low pour point petroleum product, such as the insulating oil, the lubricating oil used for various types of freezing devices, or the base oil for such lubricating oil, from a paraffin-based crude oil as the starting material without using any special rare crude oil such as naphthene-based crude oil. The catalyst comprises zeolite TSZ.
