    摘要: Biomass, including waste biomass, is gasified by a process in which the biomass is first carbonized, and the char and pyrolysis gas from the carbonizer are respectively fed to a high temperature gasifying part and a gas reformer part of a two-stage gasifier A gasifying agent is continuously fed to the gasifying part, and intermittently fed to the gas reformer, to maintain the temperature required to avoid tar formation in the gas reformer stage. Multiple carbonization chambers are operated in rotation. When the carbonization/gasification apparatus is used to provide fuel to an electric power generator set, exhaust heat from the generator power plant is fed back to the carbonizer, and can be supplemented by exchange of heat from the gas delivered to generator power plant from the outlet of the gasifier.

    摘要: A method for chemically sensitizing a silver halide photographic emulsion with a selenium compound is disclosed. The sensitizing method comprises the steps of preparing a dispersion of solid particles of a selenium compound in an aqueous medium by a process comprising the following steps of (1) dissolving a substantially water-insoluble organic selenium compound in a substantially water immiscible low-boiling organic solvent to prepare a selenium compound solution, (2) dispersing the selenium compound solution in water or an aqueous solution of a dispersing aid to form a oil-in-water type dispersion, and (3) removing the organic solvent from the oil-in-water type dispersion by stirring the dispersion under a decompressed condition to precipitate the selenium compound so as to form a dispersion of fine solid particles of the selenium compound having an average particle size of 10 nm to 3 .mu.m;adding the solid dispersion particles of the selenium compound to a silver halide emulsion, and ripening the silver halide emulsion in the presence of the solid dispersion particles of the selenium compound.
