Abstract

The present invention relates to a process for improving the pour point of a feed including paraffins containing more than 10 carbon atoms. Desirably, the feed to be treated is brought into contact with a catalyst based on NU-85 zeolite, at least partially in its acid form, and at least one hydro-dehydrogenating element, at a temperature which is in the range 170° C. to 500° C., a pressure in the range 1 to 250 bar and at an hourly space velocity in the range 0.05 to 100 h−1, in the presence of hydrogen in a proportion of 50 to 2000 l/l of feed.
