Further, the effect of said traditional fuel treating materials such as active carbon, zeolite, ceramics and the like to treat the fuel may not be enough. DISCLOSURE OF THE INVENTION According to this .invention there is provided a fuel treating device according to claim 1. The fuel in the present invention is such as light oil, gasoline, kerosene and the like, and as the arrangement of said fuel treating materials (16) in said fuel treating container (12), it is that said fuel treating material (16) is molded into grain shape and a plural number of the resulting grain-shaped fuel treating materials (16) are separately arranged in said fuel treating container (12). As said fuel treating material (16), ceramic block is preferable material and as said ceramic block, activated ceramics which is prepared by dipping a ceramics in an aqueous solution of a crystal produced by dissolving ferric chloride in a large amount of aqueous solution of sodium hydroxide, neutralizing said aqueous solution by aqueous solution of hydrochloric acid, and concentrating said neutralized aqueous solution, or dissolving ferrous sulfa.te in a large amount of aqueous solution of hydrochloric acid and concentrating said solution, or contacting a ceramics with the air passed through said aqueous solution of said crystal. In said fuel treating device (11), a fuel is put into said fuel treating container (12) through said fuel entrance (14). Said fuel is treated by contacting with said fuel treating material (16). Said fuel treating material (16) may be moved by flow pressure of said fuel in said fuel treating container (12) when said fuel contacts with said fuel treating material (16) and said fuel may be agitated by said movement of said fuel treating material (16) and as a result, the contacting efficiency between said fuel treating material (16) and said fuel may be much improved. In this case, when a plural number of said grain-shaped fuel treating materials (16) are separately arranged in said fuel treating container (12), said grain-shaped fuel treating materials (16) may roll and move in, said fuel treating container (12) by the flow pressure of said fuel and said fuel may be agitated by said rolling or moving of said grain-shaped fuel treating materials (16) and as a result, the contacting efficiency between said fuel treating materials (16) and said fuel may be much improved. In a case where a ceramic block is used as a fuel treating material (16), the molecular or cluster of the fuel may become small by the far infrared radiation from said ceramic block to improve the qualities of said fuel. To activate above described effect of said ceramic block, it is desirable to treat the fuel as follows: When ferric chloride is dissolved in a large amount of aqueous solution of sodium hydroxide, it seems that iron in said ferric chloride is activated. When the aqueous solution containing said activated iron is neutralized, crystal of chloride of said activated iron is obtained. Further, when ferrous sulfate is dissolved in a large amount of aqueous solution of hydrochloric acid, it seems that iron in said ferrous sulfate is activated. When the aqueous solution containing said activated iron is concentrated, crystal of chloride of said activated iron is obtained. The resulting crystal prepared by above described two methods is preferably purified by dissolving said crystal in a mixture of iso-propanol and water and concentrating said solution to recrystallize. When said crystal is dissolved in water, said aqueous solution may contain chloride of said activated iron and the effects of said ceramic block may be amplified by dipping said ceramic block in said aqueous solution or' contacting the air passed through said aqueous solution. Ceramics used in the present invention may be well-known ceramics such as silicon oxide, aluminium oxide, zirconium oxide, titanium oxide, silicon nitride, boron nitride, silicon carbide and the like and two or more kinds of said ceramics may be mixed and one of desirable combinations may be a mixed ceramics consisting of silicon oxide and aluminium oxide.
