METHOD FOR PRODUCING FUEL OIL

摘要

Provided is a method that is for producing fuel oil and that is able to cheaply and highly efficiently produce a fuel oil—or starting material thereof—having as the primary component n-paraffin or isoparaffin from a starting material oil containing triglyceride fatty acids, even while reducing hydrogen pressure. The method for producing fuel oil has a step for producing fuel oil having one or both of n-paraffin and isoparaffin as the primary component by contacting hydrogen gas and a starting material oil containing triglyceride fatty acids under the condition of a hydrogen pressure of no greater than 2 MPa to a catalyst resulting from supporting on a porous metal oxide support one or more metal elements belonging to group nine or group ten of the periodic table, and one or more group six element oxides belonging to group six of the periodic table. The weight ratio of the group six elements to the metal elements contained in the catalyst is no greater than 1.0 in terms of the metal.

主权项

1. A method for producing fuel oil, comprising: a step for producing a fuel oil composed mainly of one or both of n-paraffin and isoparaffin by contacting:
a base oil containing fatty acid triglyceride, and hydrogen gas with a catalyst, obtained by supporting one or a plurality of metal elements belonging to group 9 or group 10 of the periodic table and one or a plurality of group VI element oxides belonging to group 6 of the periodic table on a porous metal oxide support, under conditions of a hydrogen pressure of 2 MPa or less; wherein, the weight ratio as metal of the group 6 element contained in the catalyst to the metal element does not exceed 1.0.
