Abstract
Official abstract text for this publication.
An object of the present invention is to provide a method for hydrogenating a biodiesel fuel for producing a biodiesel fuel having an excellent oxidation stability and cold flow property. The present invention serves to produce a biodiesel fuel excellent in oxidation stability, by hydrogenating a biodiesel fuel with oxygen present in the reaction system in the presence of a catalyst containing at least one type of noble metal selected from metals of Groups 8 to 10 in the periodic table.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for hydrogenating a biodiesel fuel, the method comprising hydrogenating a biodiesel fuel in the presence of a catalyst containing at least one type of noble metal selected from the group consisting of metals of Groups 8 to 10 in the periodic table, wherein oxygen is allowed to be present in the reaction system, wherein a concentration of the oxygen in terms of oxygen molecules in the biodiesel fuel is from 150 ppm to 3,500 ppm. 2. The method for hydrogenating a biodiesel fuel according to claim 1 , comprising introducing a gas containing oxygen into the reaction system. 3. The method for hydrogenating a biodiesel fuel according to claim 1 , comprising forcibly oxidizing the biodiesel fuel in advance.
