Disclosed are a method and an apparatus for removing methane from a gas which contains the methane at such a low concentration as not to be rendered into a combustible range with whatever ratio of air mixed therewith. In order to ensure satisfactory methane removal performance even in the coexistence of sulfur compound and in order also to provide stable methane removal performance for an extended period of time without performance deterioration even when the methane concentration varies significantly, the gas is fed to a heat exchanger for preheating and methane is exposed to an oxidation catalyst which oxidizes the methane through contact therewith. Then, the resultant gas is fed again to the heat exchanger for heat recovery through heat exchange with un-reacted gas. Further, the flow rate of gas to be treated is varied, according to a concentration of the methane contained in this treated gas.

An object of the present invention is to provide a method for producing a liquefied fuel oil using biomass as a feedstock, in which a relatively inexpensive liquefaction apparatus is used; a good balance is maintained between the liquefaction of water-insoluble lignin and the liquefaction of water-soluble cellulose to achieve a high yield of the liquefied fuel oil based on the biomass solids content; and the amount of ash derived from an alkali catalyst and the like is low. The method for producing a liquefied fuel oil using biomass as a feedstock is characterized by adding, to biomass comprising lignocellulose, a solvent comprising an organic solvent and having a moisture content adjusted to 10 to 25 wt %, including moisture contained in the biomass, and liquefying the biomass at a temperature of 250 to 350&#xb0; C.

Method for producing liquefied fuel oil using biomass as feedstock

Provided herein is a method for producing a water-insoluble liquefied fuel oil containing a hydrocarbon from biomass. The method includes converting an oxygen-containing compound in a liquefied fuel oil obtained after liquefaction to a hydrocarbon and converting a water-soluble organic substance contained in an aqueous phase to a hydrocarbon, thereby improving the yield of the water-insoluble liquefied fuel oil.

A piston allowing a lubrication layer of a resin coating with a low friction coefficient to be tightly adhered to a skirt portion of a piston for an internal combustion engine, with low friction, superior wear resistance, and superior anti-seizing properties and that can reduce wear of a cylinder inner wall even if the lubrication layer is peeled off or abraded, is provided. Metal or ceramic fine particles having an average particle diameter of 20 &#x3bc;m to 400 &#x3bc;m are injected with compressed air or compressed nitrogen as a mixture fluid onto the skirt portion of the piston, made of an aluminum alloy and produced by a method such as casting or forging, at an injection speed of 80 m/s or more or an injection pressure of 0.2 MPa or more to be collided with the skirt portion, thereby uniformly making a microstructure of a piston base material fine-grained in a depth range of 1 &#x3bc;m to 15 &#x3bc;m from a surface of the skirt portion and forming a modified layer with an activated surface. A lubrication layer is formed on the modified layer, for example, by applying a resin with a low friction coefficient, while a surface of the modified layer is being activated.
