Abstract: An ink-jet recording sheet, comprising a support having thereon a porous ink receiving layer, the porous ink receiving layer including inorganic particles, a hydrophilic binder and a polymer, wherein the polymer has a plurality of carbon-carbon unsaturated bonds, provided that the unsaturated bonds are non-aromatic; the polymer has a recurring unit derived from butadiene or isoprene.

Abstract: A silver halide photographic light sensitive material comprising a transparent support and provided thereon a light sensitive layer containing a yellow coupler, a magenta coupler and a cyan coupler to form a monochromatic image upon color development after exposure, wherein a relative coupling rate of the magenta coupler with an oxidation product of a color developing agent is higher than that of the yellow or cyan coupler.

Abstract: Disclosed are a silver halide light-sensitive material for forming a monochrome-image which material is colored in orange, a silver halide light-sensitive material for forming a monochrome-image which material has an identical printing level as at least one of the silver halide color light-sensitive materials provided for a negative-positive type color photographic system, and a photo-taking unit loading and packaging in a photographable state at least one of the monochrome image forming silver halide light-sensitive material. The invention provides a silver halide light-sensitive material for forming a monochrome-image which is suitable for a negative-positive system color photographic processing and is easy for printing onto a photographic paper.

Abstract: A catalyst including a first catalyst ingredient which is at least one element selected from a group consisting of Pt, Pd and Ir, or oxides thereof; and further able to include at least one element selected from a group consisting of Au, Ag, Cu, Fe, Sb, Se, Te and Ta, or oxides thereof, as a second catalyst ingredient, carried on at least one of a silica-boria-alumina composite oxide or a zeolite with a silica-to-alumina molar ratio of more than 30, in amounts of from 0.1 to 10 g of the first catalyst ingredient and from 0.01 to 5 g of the second catalyst ingredient based on one liter of the catalyst with the second to first catalyst ingredient weight ratio being less than 1.

Abstract: A method for removing nitrogen oxides and organic chlorine compounds from a combustion waste gas, which comprises the steps of: adding ammonia (NH.sub.3) as a reducing agent to a combustion waste gas containing nitrogen oxides and organic chlorine compounds; causing the combustion waste gas added with ammonia to contact with, while keeping the temperature of the combustion waste gas within a prescribed range, with a catalyst comprising at least one selected from the group consisting of platinum (Pt), palladium (Pd), ruthenium (Ru), manganese (Mn), copper (Cu), chromium (Cr) and iron (Fe) and oxides thereof, supported on the surface of a carrier comprising at least one selected from the group consisting of titanium oxide (TiO.sub.2), silicon oxide (SiO.sub.2), aluminum oxide (Al.sub.2 O.sub.3) and zirconium oxide (ZrO.sub.2), thereby removing nitrogen oxides and organic chlorine compounds from the combustion waste gas.

Abstract: A method for removing detrimental organic chlorine compounds such as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans from a combustion waste gas, which comprises the steps of: bringing organic chlorine compounds contained in a combustion waste gas at a temperature within a range of from 150.degree. to 350.degree. C. into contact with a catalyst comprising at least one selected from the group consisting of platinum, palladium, ruthenium, manganese, copper, chromium and iron and oxides thereof, which catalyst is supported on the surface of a carrier containing at least titanium oxide, Aluminum oxide and silicon oxide, to cause a decomposition reaction of the organic chlorine compounds, thereby removing organic chlorine compounds from the combustion waste gas at a high efficiency.

Abstract: A circulating fluid-bed combustion apparatus comprises a fluid-bed combustion chamber having a primary combustion air inlet and secondary combustion air inlet, the primary combustion air inlet arranged at the bottom of the fluid-bed combustion chamber and the secondary combustion air inlet being arranged in an intermediate portion of the fluid-bed combustion chamber; a layrinth separator for separating coarse particles from gases, which is positioned below the secondary combustion air inlet; a heat exchanger, into which combustion gases are led from the fluid-bed combustion chamber; a multicyclone for separating fine particles from gases discharged out of the heat exchanger; and a distributor for distributing particles separated in the multicyclone to an upper zone of the fluid-bed combustion chamber above the labyrinth separator and to a lower zone of the fluid-bed combustion chamber below the labyrinth separator.
