(57)Abstract<br />

The invention concerns a process for irnproving <strong>the</strong> pour point <strong>of</strong> a feed comprising paraffins containing more than 10<br />

carbon atoms, in which process <strong>the</strong> feed to be treated is brought into contact with a catalyst comprising NU-86 zeolite<br />

and at least one hydro-dehydrogenating element, at a temperature which is in <strong>the</strong> range 170Û & WR Û & D SUHVVXUH LQ<br />

<strong>the</strong> range 1 to 250 bar and an hourly space velocity in <strong>the</strong> range 0.05 to 100h -1 , in <strong>the</strong> presence <strong>of</strong> hydrogen in a<br />

proportion <strong>of</strong> 50 to 2000 1/1 <strong>of</strong> feed. The product from heavy feeds is fractionated to produce at least one cut<br />

including at least one middle distillate with a reduced pour point, and a residue including oil bases with a reduced<br />

pour point and a high viscosity index.<br />

The NU-86 zeolite is preferably dealuminated.<br />
