A C10 mono-olefin feedstock, C15 mono-olefin feedstock, C20 mono-olefin feedstock, or C30 mono-olefin feedstock prepared by the method comprising:
- a) in a first stage, reacting conjugated alkenes comprising at least one conjugated diene and at least one additional olefinic bond with hydrogen in the presence of a first catalyst under conditions suitable to preferentially hydrogenate at least one olefinic bond in the conjugated diene to produce partially hydrogenated intermediates;
- and
- b) in a second stage, reacting the partially hydrogenated intermediates with hydrogen in the presence of a second catalyst to produce an olefinic feedstock;
- wherein the catalyst, catalyst loading, temperature or hydrogen pressure is varied between the first stage and the second stage so as to favor hydrogenation of partially hydrogenated intermediates having more than one olefinic bond over hydrogenation of partially hydrogenated intermediates having one olefinic bond;
- and
- wherein the olefinic feedstock comprises at least about 55% mono-olefin.
An olefinic feedstock comprising at least about 60% mono-olefin C10-C30 terpene and less than about 25% alkane;
- at least about 65% mono-olefin C10-C30 terpene and less than about 25% alkane;
- at least about 70% mono-olefin C10-C30 terpene and less than about 20% alkane;
- or at least about 75% mono-olefin C10-C30 terpene and about 10% or less alkane.
An olefinic feedstock comprising at least about 55% mono-olefin C10-C30 terpene and about 10% or less di-olefin;
- at least about 55% mono-olefin C10-C30 terpene and about 5% or less di-olefin;
- at least about 55% mono-olefin C10-C30 terpene and about 3% or less di-olefin;
- or at least about 60% mono-olefinic C10-C30 terpene.
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 to make a composition comprising at least about 55% mono-olefinic species and at most about 10% di-olefinic species.
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 to make a composition comprising at least about 65% mono-olefinic species.
