20100227229 | SOLID ACID, METHOD FOR PREPARING THE SOLID ACID, AND METHOD FOR DESULFURIZING HYDROCARBON OIL USING THE SOILD ACID AS DESULFURIZING AGENT - [Problems] To provide a method for desulfurization with a desulfurizing agent, which can efficiently desulfurize, for example, a hydrocarbon oil as a raw material and fuel for generating hydrogen for use in fuel cells, particularly kerosenes and light oils, without the need to use reduction treatment and hydrogen and at a temperature from room temperature to about 100° C., and a fuel cell system using the desulfurization method. There are also provided a solid acid useful as a constituent of the desulfurizing agent for use in the desulfurization method, and a process for producing the solid acid. | 09-09-2010 |
20100155303 | METHOD FOR DESULFURIZATION OF HYDROCARBON OIL - Disclosed is a method for desulfurization of a hydrocarbon oil (e.g., kerosene which is a raw fuel for a fuel cell) which can effectively remove benzothiophenes and dibenzothiophenes contained in the hydrocarbon oil under mild conditions to produce a desulfurized hydrocarbon oil having a significantly low sulfur content. | 06-24-2010 |
20090318317 | LUBRICATING OIL FOR FLUID BEARING, AND FLUID BEARING AND METHOD FOR LUBRICATING FLUID BEARING BY USING THE LUBRICATING OIL - Disclosed is a lubricating oil for a fluid bearing, which has a low viscosity, a reduced amount of evaporation, and superior low-temperature flowability. The lubricating oil includes, as a base oil, a high-purity diester synthesized from a carboxylic acid material containing 90 mass % or more of azelaic acid and an alcohol material containing 90 mass % or more of 2-ethyl-1-hexanol. The carboxylic acid material contains glutaric acid, adipic acid, pimelic acid, suberic acid, sebacic acid and 1,9-nanomethylenedicarboxylic acid in a total amount of 5 mass % or less. | 12-24-2009 |

20090314683 | METHOD FOR PRODUCING HYDROCARBON FRACTIONS - A method for producing an LPG fraction, a gasoline fraction, a kerosene fraction, a gas oil fraction, monocyclic aromatic hydrocarbon and a non-aromatic naphtha fraction from hydrocracked oil includes hydrocracking hydrocarbon oil containing polycyclic aromatic hydrocarbon to convert into a light hydrocarbon fraction, and efficiently and selectively producing monocyclic aromatic hydrocarbon with higher valuable alkylbenzenes. The method for producing hydrocarbon fraction comprises subjecting hydrocarbon feedstock containing polycyclic aromatic hydrocarbon and in which the ratio of carbons constituting an aromatic ring to the total carbons in the hydrocarbon oil (the aromatic ring-constituting carbon ratio) is 35 mole % or more to catalytic cracking in the presence of hydrogen. 40% or more of a fraction with a boiling point of 215° C. or higher in the hydrocarbon feedstock is converted into a fraction with a boiling point lower than 215° C., producing hydrocracked oil containing 30 vol % or more of monocyclic aromatic hydrocarbon. | 12-24-2009 |
