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&#xb0; 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.

Thermal methods for treating a metathesis feedstock

Various methods are provided for metathesizing a feedstock. In one aspect, a method includes providing a feedstock including a natural oil, chemically treating the feedstock 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.

A hybrid wax compositions that are suitable for use in manufacturing wax articles (e.g., candles) by compression molding. The combination of a hydrogenated natural oil-based wax and a paraffin wax having a select distribution of hydrocarbon chain lengths provides the hybrid wax compositions with improved properties, such as improved compressive strength and improved de-molding characteristics, for example, as evidenced by reducing scarring and/or flashing. The hybrid wax compositions comprise: (a) a wax comprising a hydrogenated natural oil; and (b) a paraffin wax, wherein the paraffin wax comprises less than about 50% by weight of the hybrid wax composition, and wherein about 52% or greater of hydrocarbons in the paraffin wax have carbon chain lengths ranging from C25 to C29.

Various methods are provided for metathesizing a feedstock. In one aspect, a method includes providing a feedstock comprising a natural oil, chemically treating the feedstock 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.

A candle and process for making it are disclosed. The candle comprises prilled wax particles, comprising hydrogenated natural oil and wherein at least 75% of the prilled wax particles are less than 800 &#x3bc;m in diameter. The candle includes a compressed core and a thermally fused outer layer.
