Abstract
The conversion of hydrocarbons in the presence of hydrogen occurs under hydrocarbon conversion conditions in the presence of a subgroup of a certain class of metal-substituted semi-crystalline aluminosilicates which are synthetic and which are predominantly ordered in two directions, that is, which are laminar or have a layered or stacked sheet structure. The metal substituted for the aluminum in the trioctahedral sites is nickel, cobalt, or mixtures thereof. Hydrocarbon conversion catalysts are also claimed comprising the metal-substituted laminar 2:1 layer lattice aluminosilicate minerals containing in addition a hydrogenation component such as palladium. The catalysts are preferably used in hydroisomerization and hydrocracking processes.

- [(Al.sub.4.sub.-ew.sup.3.sup.+ Y.sub.3w.sup.2.sup.+).sup. VI (Q.sub.8.sub.-x.sup.4.sup.+ Al.sub.x.sup.3.sup.+).sup.IV O.sub.20 (OH).sub.4.sub.-f F.sub.f].sup.. [dC.sup.Y ]
- where
- Al is aluminum;
- Y is selected from the class consisting of nickel, cobalt and mixtures thereof;
- Q is at least 0.95 mol fraction silicon ions, the remainder consisting of tetravalent ions having an ionic radius not to exceed 0.65 A;
- and
- F is fluorine;
- C is at least one charge-balancing cation:
- and where e has a numerical value from 2 to 3 inclusive;
- w has a numerical value from 0.01 to 2 inclusive, with the proviso that the quantity ew have a numerical value from 0.02 to 4 inclusive:
