Abstract
Various methods are provided for metathesizing a feedstock. In one aspect, a method includes providing a feedstock comprising a natural oil, heating the feedstock to a temperature greater than 100° C. in the absence of oxygen, holding the feedstock at the temperature for a time sufficient to diminish catalyst poisons in the feedstock, and, following the heating and holding, combining a metathesis catalyst with the feedstock under conditions sufficient to metathesize the feedstock.
Claims18
A method of metathesizing a feedstock, comprising:
- providing a feedstock comprising a natural oil;
- treating the feedstock;
- and
- introducing a metathesis catalyst to the treated feedstock under conditions sufficient to metathesize the natural oil;
- wherein the treating comprises heating the feedstock to a temperature greater than 100° C. and holding the temperature of the feedstock at a temperature greater than 100° C. for a period of time so as to reduce the concentration of peroxides in the feedstock.
