Claims
- 1. A process for dewaxing a hydrocarbon feedstock containing paraffins which comprises contacting the feedstock with a catalyst comprising a transition metal alumino-silicate IOZ- 5 which has had the transition metal substantially extracted therefrom and having the x-ray diffraction pattern substantially that set forth in Table I and having a silica:alumina ratio of at least 5:1, and a metal hydrogenation component under dewaxing conditions.
- 2. A process according to claim 1 wherein the crystalline alumino-silicate has a silica:alumina ratio of at least 8:1.
- 3. A process according to claim 1 in which the feedstock includes aromatic components in addition to the paraffins.
- 4. A process according to claim 3 in which the proportion of aromatic components is from 0 to 50 weight percent of the feedstock.
- 5. A process according to claim 2 in which the IOZ-5 has a silica/alumina ratio of at least 12:1.
- 6. A process according to claim 1 in which the hydrogenation component comprises a metal, oxide or sulfide of Group VIII of the Periodic Table.
- 7. A process according to claim 6 in which the hydrogenation component comprises platinum or palladium.
- 8. A process according to claim 1 in which the feedstock is contacted with the catalyst in the presence of hydrogen at a temperature from about 200.degree. C. to about 550.degree. C., a pressure from about atmospheric to about 18 MPa, and a space velocity from about 0.1 to about 20 v/v/h.
- 9. A process according to claim 8 in which the feedstock is contacted with catalyst in the presence of hydrogen at a temperature from about 250.degree. C. to about 480.degree. C. and a pressure from about 1.2 to about 10 MPa and a space velocity from about 0.1 to about 10 v/v/h.
