Description

 Description Blended gasoline and its storage and Z or supply systems

 The present invention relates to a mixed gasoline comprising a mixture of fuel for a fuel cell system and gasoline. The present invention also relates to a storage and Z or supply system for the blended gasoline. Background leakage

 In recent years, the growing sense of crisis against the Earth's difficulties

—The development of a supply system is required. In particular, reduce CO _{2 to} prevent global warming, THC (unreacted hydrocarbon in exhaust gas), NOx, PM (particulate matter in exhaust gas: high boiling point of fuel and lubricating oil. It is required to reach a high level of reduction of harmful substances such as unburned components of adultery. Specific examples of such systems include an automotive power system that replaces the conventional Otto-Dieselé system or a power generation system that replaces thermal power.

Thus we have the energy efficiency is close to ideal, the fuel cell is in ¾Φ manner does not emit only H ₂ 0 and C0 _2, is expected as the most promising systems meet the needs of society. And to achieve such a system, it is essential to develop not only equipment technology but also R¾ fuel.

 Toru: Hydrogen, methanol, and hydrocarbon fuels are known as fuels for fuel cell systems. Disclosure of the invention

As a fuel for fuel cell systems, hydrogen is advantageous in that it does not require a special reformer, but because it is gaseous, it has problems with storage and mounting on vehicles, etc. Requires special equipment. Also, the danger of bow I fire is high and care must be taken when handling. Methanol is advantageous in that it is relatively easy to reform to 7j <element, but its power generation by weight is small and it is toxic, so handling it is necessary. In addition, since it is corrosive, special equipment is required for storage and supply.

 Hydrocarbon-based fuels have excellent storage properties and are easy to mount on vehicles, etc. In particular, supply and supply at existing 1 ^ screw stations are T-functional, and there are great expectations for infrastructure. However, in conventional gasoline, the sulfur content and additives contained in the gasoline have been known to affect the electrodes used in the reforming reaction of fuel cells and the electrodes of fuel cells (especially solid high-type). Gasoline in Agata could not be used as fuel for fuel cells.

In order to sufficiently exhibit the capability of the fuel cell system, a fuel cell system for fuel, it is often the power generation amount per weight, it generation per co ₂ emissions is large, the entire fuel cell system Low fuel consumption, low reforming fiber, water gas shift reaction catalyst, carbon monoxide removal M¾, fuel cell stack, etc., with low deterioration of fuel cell system, long-lasting initial performance, short system startup time And good handling such as storage stability and flash point are required. In addition, in the fuel cell system, it is necessary to keep the fuel and the porcelain at specified levels, so the required amount of heat (the heat S that balances the heat generated by the preheating and the reaction) is subtracted from the generated power. The amount is the amount of power generated by the entire fuel cell system. Therefore, the lower the amount required for reforming the fuel, the lower the preheat amount, which is advantageous, the shorter the system startup time, and the lower the heat amount per weight required for fuel preheating. It is also necessary. Insufficient preheating: ^ High levels of unreacted hydrocarbons (THC) in the exhaust gas not only reduce power generation per weight, but can also cause air pollution. Conversely, at the age when the same system is operated in the same way, IJ is the method of reducing the amount of THC in the exhaust gas and changing to hydrogen.

On the other hand, existing service stations and oil tankers have fuel storage tanks for each product such as 8-octane gasoline, regular gasoline, diesel, and kerosene. Therefore, when supplying hydrocarbon fuel for fuel cells, it is necessary to add a dedicated tank at the service station ゃ oil depot in consideration of the fact that existing products will be combined at the same time. There was a need to re-implement it. In view of such circumstances, the present invention provides a fuel for gasoline-powered automobiles (mixed gasoline) by mixing a fuel for gasoline-powered automobiles with a fuel for a fuel cell system, thereby avoiding an increase in storage facilities. Aim. Another object of the present invention is to provide a storage and / or supply system for the mixed gasoline, which avoids an increase in storage facilities.

For each of these fuels, a fuel cell system test and a gasoline fuel evaluation test were conducted. Fuel cell system II test

 (1) Steam reforming type

The fuel and water were vaporized by the electric train, and the precious metal thighs were filled and led to a reformer maintained at a predetermined temperature by an electric heater, thereby generating a reformed gas rich in hydrogen.

 The value of the reformer was set to the lowest level at which the reforming was completely performed in the initial stage of the test (the minimum level where the reformed gas did not contain THC! ^).

 The reformed gas is led to a carbon monoxide treatment unit (ice gas shift reaction) together with water vapor to convert carbon monoxide in the reformed gas into carbon dioxide, and the generated gas is guided to a polymer electrolyte fuel cell to generate electricity. Natsuta

 Fig. 3 shows a flow chart of the steam reforming type fuel cell system used in ①. (2) Partial acid

The fuel is vaporized by heat, and the preheated air is filled with precious metal-based gas and led to a reformer at 110 ° C with an electric heater to generate reformed gas rich in hydrogen. Let me know.

 The reformed gas is led to a carbon monoxide treatment device (water gas shift reaction) together with water vapor to convert carbon monoxide in the reformed gas into carbon dioxide, and the generated gas is guided to a polymer electrolyte fuel cell to generate electricity. Was.

Fig. 4 shows a flowchart of the partial oxidation fuel cell system used for the evaluation. (3) Satsu method

It was measured for _{H 2, CO, C0 2,} THC amount of reformed gas generated from the reformer immediately after the start of the test. Similarly, immediately after the start of the Iflffi test, the amounts of H ₂ , C〇, C〇 ₂ , and THC in the reformed gas generated from the carbon monoxide treatment equipment were measured. Immediately after the start of the l ^ ffi test and 100 hours after the start of II, power generation, fuel consumption, and CO ₂ emissions from the fuel cell were measured. The amount of heat (preheating *) required to guide each fuel to the specified reformer was calculated from the heat capacity and latent heat of vaporization.

 In addition, based on these measured values' calculated values and fuel calorific value, the performance of the reformed inserts was inferior to ibfiJ (power generation 100 hours after the start of the test * / power generation immediately after the start of the test 、), fiber rate (power generation immediately after the start of the test * / Fuel heat *) and preheat rate (preheat * / power generation *) were calculated. Gasoline fuel test for automobile

The operability at 显 (25 ° C) when driving according to the driving pattern transferred to the CRC method described in “CRC Report No. 483” was reduced. Based on the demerit points given by the phenomena shown in Table 8 for the phenomena shown in Table 8 that occurred in the TI subjects shown in Table 7, and the coefficients associated with the contents shown in Table 9, j X “Coefficients” were calculated, and finally all items were tabulated and stated. The higher the number of points, the more problems it has to use as gasoline. It can be said that there is no problem in using a vehicle having an evaluation score of 40 or less as gasoline for automobiles, and a case of 30 or less is more preferable.

The invention's effect

 As described above, the fuel for gasoline vehicles and the fuel for the fuel cell system are mixed to provide the fuel for gasoline vehicles (mixed gasoline), which results in three types of storage using two storage units (tanks). Supply fuel (high octane gasoline, regular gasoline, fuel for fuel cell system). This can avoid an increase in storage facilities. Further, the present invention can provide a storage and Z or supply system for undesired S-mixed gasoline while avoiding an increase in storage facilities.
