Benefits of technology

The solution provides an aviation fuel with excellent life-cycle characteristics, carbon neutrality, and improved specific fuel consumption, contributing to environmental sustainability and primary energy diversification.

Problems solved by technology

However, as described in the following Patent document 1, in the step of manufacturing FAME, problems have been indicated that a by-product glycerin is required to be treated, or cost and energy are required for the cleaning of a produced oil or the like.
Further, regarding the oxidation stability, the addition of an antioxidant is defined as aviation fuel specifications, however, in view of the stability as a base, as with the low-temperature performance, the mixing ratio has to be limited to a low concentration.
However, the hydrocarbon by these techniques generally has a low density, and it was a point of concern that even in case of using for an aviation fuel, the density is reduced when mixed at a high concentration, resulting in degradation of fuel efficiency.

example 1

[0087]A feedstock A was prepared by adding dimethylsulfide to a vegetable fat and oil 1 so that the sulfur content (in terms of sulfur atom) is 10 mass ppm. The feedstock A was hydrotreated using the catalyst A shown in Table 1 under the condition a shown in Table 3. The hydrotreated oil was isomerized using the catalyst B shown in Table 1 under the condition b shown in Table 3. A fraction having a boiling range of 140 to 280° C. obtained from the isomerized oil after isomerization was used as a base 1. The properties of the base 1 are shown in Table 4. An aviation fuel oil composition 1 was prepared by mixing the base 1 with 30 vol % of a catalytic cracking kerosene having the properties shown in Table 2 obtained from a fluid catalytic cracking apparatus.

example 2

[0088]A feedstock B was prepared by adding dimethylsulfide to a vegetable fat and oil 2 having the properties shown in Table 2 so that the sulfur content (in terms of sulfur atom) is 10 mass ppm. The feedstock B was hydrotreated using the catalyst A shown in Table 1 under the condition c shown in Table 3. A fraction having a boiling range of 140 to 280° C. obtained from the hydrotreated oil was isomerized using the catalyst B shown in Table 1 under the condition b shown in Table 3. The isomerizing oil after isomerization was cut by distillation into a fraction having a boiling range of 140 to 280° C. to obtain a base 2. The properties of the base 2 are shown in Table 4. An aviation fuel oil composition 2 was prepared by mixing the base 2 with 30 vol % of a hydrocracked kerosene having the properties shown in Table 2 obtained from a heavy oil hydrocracking apparatus.

example 3

[0089]An aviation fuel oil composition 3 was prepared by mixing the aviation fuel oil composition 2 described in Example 2 with 30 vol % of a petroleum-based aviation fuel oil base having the properties shown in Table 2 obtained by refining a crude oil.

Abstract

To provide an aviation fuel oil composition which has excellent life cycle characteristics and achieves excellent specific fuel consumption. The aviation fuel oil composition according to the present invention includes: a first base which is a fraction having a boiling range of 140 to 280° C. obtained through a step of hydrotreating a first feedstock containing a sulfur-containing hydrocarbon compound and an oxygen-containing hydrocarbon compound derived from an animal or vegetable oil and fat or a second feedstock which is an oil blend of the first feedstock and a petroleum-based base obtained by refining a crude oil; and a second base which is a fraction having a boiling range of 140 to 280° C. obtained from a heavy oil cracking apparatus.

Description

CLAIM FOR PRIORITY[0001]This application is a Continuation of U.S. application Ser. No. 13 / 391,891, which is a National Phase Application of International Application PCT / JP2010 / 064700, filed Aug. 30, 2010, and claims the priority benefit of Japanese Application No. 2009-200695, filed Aug. 31, 2009. The disclosures of U.S. application Ser. No. 13 / 391,891 and PCT / JP2010 / 064700 are expressly incorporated by reference in their entireties.TECHNICAL FIELD[0002]The present invention relates to an aviation fuel oil composition.BACKGROUND ART[0003]Attention is paid to the effective utilization of biomass energy as a preventive measure against global warming. Above all, since biomass energy derived from vegetables can effectively use carbon fixed from carbon dioxide in the atmosphere by photosynthesis during the growth process of vegetables, it has a property which is so-called carbon neutral and may not contribute to the increase in carbon dioxide in the atmosphere from the viewpoint of the...
