Abstract
The invention concerns a catalyst containing by weight: PA0 (a) from 10 to 99.99% of a mordenite being in major part shaped as needles and having a Si/Al atomic ratio of about 5 to 50, a benzene adsorption capacity of more than 5% by weight with respect to the dry mordenite weight, a volume V of a unit cell from 2.73 to 2,78 nm.sup.3, a sodium content by weight lower than 0.2% and adsorbing molecules of a kinetic diameter larger than about 6.6.times.10.sup.-10 m, PA0 (b) from 0 to 89.99% of a matrix, PA0 (c) from 0.005 to 15% of at least one metal from group VIII, and PA0 (d) from 0.005 to 10% of at least one metal from group IV A. The catalyst is used for hydroisomerizing cuts containing a high proportion of normal paraffins having 4, 5, 6 or 7 carbon atoms per molecule to obtain with a good conversion and selectivity a mixture containing a high proportion of isoparaffins.
