Claims
- 1. A process for alkylating normally solid, waxy hydrocarbons to liquid hydrocarbons boiling primarily in the lube oil range which comprises contacting said waxy hydrocarbons with a low molecular weight olefin and with a catalyst consisting essentially of one or more C.sub.3 -C.sub.5 carbon atom secondary alcohols at elevated temperature and pressure to alkylate a substantial portion of the wax to relatively high VI, low pour point lube oil components.
- 2. The process of claim 1 wherein said olefin is selected from the group consisting of C.sub.2 -C.sub.10 carbon atom olefins and mixtures thereof.
- 3. The process of claim 2 wherein said olefin is selected from the group consisting of C.sub.2 -C.sub.5 carbon atom olefins and mixtures thereof.
- 4. The process of claim 3 wherein said waxy hydrocarbons are obtained from natural or synthetic petroleum oils.
- 5. The process of claim 4 wherein said elevated temperature and pressure range from between about 300.degree. to 1000.degree. F. and 100 to 5000 psig, respectively.
- 6. The process of claim 5 wherein the ratio of said catalyst to said waxy hydrocarbons ranges from about 0.1 to 10 wt.% of said waxy hydrocarbon.
- 7. A process for alkylating wax derived from natural and synthetic petroleum oils which comprises contacting said wax and a C.sub.2 -C.sub.10 carbon atom olefin in a reaction zone at elevated temperature and pressure with a catalyst consisting essentially of one or more C.sub.3 -C.sub.5 carbon atom secondary alcohols to alkylate a portion of said wax to relatively high VI, low pour point lube oil components.
- 8. The process of claim 7 wherein said elevated temperature and pressure in said zone range from about 450.degree. to 850.degree. F. and 200 to 1,000 psig., respectively.
- 9. The process of claim 8 wherein the amount of olefin in the reaction zone ranges from about 2 to 10 moles of olefin per mole of wax.
- 10. The process of claim 9 wherein the amount of catalyst in the reaction zone ranges from about 0.5 to 5 wt.% of the wax in said zone.
- 11. A process for dewaxing a wax-containing lube oil stock which comprises contacting said stock with a C.sub.2 -C.sub.10 carbon atom olefin in a reaction zone at elevated temperature and pressure and with a catalyst consisting essentially of one or more C.sub.3 -C.sub.5 carbon atom secondary alcohols to alkylate a portion of said wax to lube oil components thereby producing a lube oil stock of reduced wax content and reduced pour point.
- 12. The process of claim 11 wherein said elevated temperature and pressure in said zone range from about 300.degree. to 1,000.degree. F. and 100 to 5,000 psig., respectively.
- 13. The process of claim 12 wherein said olefin is a C.sub.2 -C.sub.5 carbon atom mono-olefin.
- 14. The process of claim 13 wherein said stock is a lube oil raffinate.
