Claims
- 1. A hydrotreating process for hydrocarbon resin or rosin molecules comprising contacting said molecules with hydrogen in the presence of a bulk multimetallic hydrogenation catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIE metals and wherein the molar ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10.
- 2. The hydrotreating process of claim 1 comprising hydrotreating at a temperature of 100° C. to 330° C. and hydrogen pressure of 1013 kPa to 27.6×102 kPa.
- 3. The process of claim 2 wherein said temperature is at least 180° C. and said pressure is 1013 kPa to 15.2×103 kPa.
- 4. The process of claim 1 wherein said hydrocarbon molecules comprise petroleum resins.
- 5. The process of claim 1 wherein said hydrocarbon molecules comprise aliphatic or cycloaliphatic petroleum resins.
- 6. The process of claim 1 wherein said hydrocarbon molecules comprise aliphatic-aromatic petroleum results.
- 7. The process of claim 1 wherein said hydrocarbon resin is a natural resin or esterified rosin.
- 8. The process of claim 1 wherein said hydrocarbon resin has been prepared by Friedl-Crafts polymerization with a Lewis acid polymerization catalyst.
- 9. The process of claim 8 wherein said Lewis acid polymerization catalyst is AlCl3.
- 10. A hydrotreating process for hydrocarbon resin or rosin molecules consisting essentially of contacting of contacting said molecules with hydrogen in the presence of an unsupported bulk multimetallic hydrogenation catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals and wherein the molar ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10.
- 11. The hydrotreating process of claim 10 wherein the hydrotreating occurs at a temperature of 100° C. to 330° C. and a hydrogen pressure of 1013 kPa to 27.6×103 kPa.
- 12. The hydrotreating process of claim 11 wherein said temperature is at least 180° C and said pressure is 1013 kPa to 15.2×103 kPa.
- 13. The hydrotreating process of claim 10 wherein said hydrocarbon molecules comprise petroleum resins.
- 14. The hydrotreating process of claim 10 wherein said hydrocarbon molecules comprise aliphatic or cycloaliphatic petroleum resins.
- 15. The hydrotreating process of claim 10 wherein said hydrocarbon molecules comprise aliphatic-aromatic petroleum resins.
- 16. The hydrotreating process of claim 10 wherein said hydrocarbon resin is a natural resin or esterified rosin.
- 17. The hydrotreating process of claim 10 wherein said hydrocarbon resin has been prepared by Fridl-Crafts polymerization with a Lewis acid polymerization catalyst.
- 18. The hydrotreating process of claim 17 wherein said Lewis acid polymerization catalyst is AlCl3.
