Abstract
Various methods are provided for treating and reacting a metathesis feedstock. In one embodiment, the method includes providing a feedstock comprising a natural oil, chemically treating the feedstock with a metal alkoxide under conditions sufficient to diminish catalyst poisons in the feedstock, and, following the treating, combining a metathesis catalyst with the feedstock under conditions sufficient to metathesize the feedstock.
Claims20
A method of metathesizing a feedstock comprising:
- providing a feedstock comprising a natural oil;
- chemically treating the feedstock with a metal alkoxide under conditions sufficient to diminish catalyst poisons in the feedstock through a chemical reaction of the catalyst poisons;
- and
- following chemically treating, combining a metathesis catalyst with the feedstock under conditions sufficient to metathesize the feedstock.
1 more element
A method of metathesizing a feedstock comprising:
- providing a feedstock comprising a natural oil having a starting peroxide value;
- chemically treating the feedstock with a metal alkoxide for a time sufficient to reduce the starting peroxide value of the feedstock by approximately 80% or more through a chemical reaction of the peroxide poisons;
- following chemically treating, combining a metathesis catalyst with the feedstock under conditions sufficient to metathesize the feedstock.
