    Abstract: PROBLEM TO BE SOLVED: To provide a separation membrane for sewage waste water, which has high water permeability and in which the clogging hardly occurs and the stripping of a porous resin layer from a porous base material is prevented. SOLUTION: The separation membrane is manufactured by forming the porous resin layer on the surface of the porous base material composed of an organic fiber. A part of a resin forming the porous resin layer is infiltrated into at least the surface layer part of the porous base material to form a composite layer with the porous base material at least in the surface layer part. When the thickness of the porous base material is expressed by A, the thickness of the porous resin layer is expressed by B and the thickness of the composite layer is expressed by C, inequalities, B>=0.1A and C/B>0.1 are satisfied. When the surface roughness of the porous resin surface is =0.05 Åare not present at least in the porous resin layer and the elimination ratio of fine particles having 0.9 μm average particle diameter is at least 90%.

    Abstract: PROBLEM TO BE SOLVED: To selectively and efficiently absorb/release or decompose NOx in a waste combustion gas or a gaseous mixture by producing a NOx removing body from an oxide containing at least >=2 kinds of elements selected from aluminum, titanium, zirconium. SOLUTION: The NOx removing body for decomposing and removing NOx contained in the waste combustion gas or the gaseous mixture is produced by using the oxide containing >=2 kinds of elements selected from aluminum, titanium, zirconium. The ratio of the elements is not necessarily limited, but the ratio of titanium and/or zirconium to aluminum is preferably controlled to 0.01-20. And the NOx removing body is obtained by using a compound containing nitrogen as a raw material or an additive of a raw material in a powder producing process preferably using a metallic alkoxide solution, a metallic salt solution as a starting material and firing. And the absorbed NOx is released by heating at 200-600 deg.C.

    Abstract: PROBLEM TO BE SOLVED: To make NOx of low concentration efficiently absorbed by manufacturing a NOx absorbing material by a method wherein a raw material contains a compound such as diethanolamine represented by a specific formula at a mole ration in a specific range with respect to the amount of a compound such as aluminum ethoxide represented by a specific formula. SOLUTION: This NOx absorbing material for absorbing and removing NOx of low concentation held in combustion exhaust gas is prepared from a raw material, in which amounts of a compound represented by the formula NHx (-R -OH)y is contained at a mole ration of 0.1-20 with respect to amounts of a compound represented by the formula Al (-OR )x (-OH)y . Where x+y=3, x>=1, y>=1, R , R are each a 1-6C substituted or non-substituted aliphatic group or alicycic group. Such NOx absorbing material is manufactured by mixing the raw material in an inert gas atmosphere to dissolve it comletely and adjusting the concentration of solution preferably to 0.01-2.0 mole/l using a lower aliphatic alcohol.
