Olefins and methods for making the same
Provided herein are olefinic feedstocks derived from conjugated hydrocarbon terpenes (e.g., C 10 -C 50 terpenes), methods for making the same, and methods for their use.
1. A method comprising selectively hydrogenating a conjugated terpene comprising at least three olefinic bonds, wherein two of the at least three olefinic bonds form a conjugated diene, wherein the conjugated terpene is selected from the group consisting of a conjugated C 15 terpene, a conjugated C 20 terpene, and a conjugated C 30 terpene, wherein the selective hydrogenation occurs in a single stage reaction in the presence of a catalyst, and wherein the catalyst is not molybdenum disulfide, to make a composition comprising at least about 55% mono-olefinic species and at most about 10% di-olefinic species.
2. The method of claim 1 , wherein the method is capable of making a composition comprising at most about 5% di-olefinic species.
3. The method of claim 1 , wherein the method is capable of making a composition comprising at least about 60% mono-olefinic species and at most about 5% di-olefinic species, or at least about 65% mono-olefinic species and at most about 5% di-olefinic species.
4. A method comprising selectively hydrogenating a conjugated terpene comprising at least three olefinic bonds, wherein two of the at least three olefinic bonds form a conjugated diene, wherein the conjugated terpene is selected from the group consisting of a conjugated C 15 terpene, a conjugated C 20 terpene, and a conjugated C 30 terpene, wherein the selective hydrogenation occurs in a single stage reaction in the presence of a catalyst, and wherein the catalyst is not molybdenum disulfide, to make a composition comprising at least about 65% mono-olefinic species.
5. The method of claim 4 , wherein the method is capable of making a composition comprising at least about 70% mono-olefinic species, or at least about 75% mono-olefinic species.
