Patent number: 8551223Abstract: Unburned carbon is efficiently removed from fly ash, and effective utilization of the fly ash and removed unburned carbon is attained. Water is added to fly ash to thereby obtain a slurry. A collector is added to the slurry, and shearing force is applied to the slurry and collector to thereby attain a surface modification. The mixture is subjected to flotation operation at which unburned carbon of fly ash is attached to froths and surfaced. The application of shearing force to the slurry and collector can be carried out by means of a submerged agitator whereby an agitation power of 0.7 to 10 kWh/m3 is applied per unit quantity of slurry. The fly ash concentration of the slurry is in the range of 3 to 50 wt. %, and the amount of collector added is in the range of 5 to 100 wt. % based on the amount of unburned carbon of fly ash. The unburned carbon separated by flotation can be used as fuel, and the fly ash (product) having its unburned carbon content reduced to 1 wt.Type: GrantFiled: October 7, 2004Date of Patent: October 8, 2013Assignee: Taiheiyo Cement CorporationInventors: Shinichiro Saito, Kazuo Abe, Kosuke Kimoto, Toshiaki Murata

Patent number: 4787936Abstract: The inventive cement-based composition is useful as a coating material for corrosion-resistant protection on steel and iron surfaces. The composition is basically a polymer cement composition prepared by compounding a hydraulic cement with an aqueous emulsion of a polymeric constituent but characteritically the inventive composition is prepared by adding an aqueous emulsion of a hydrocarbon solvent such as kerosene containing a combination of surface active agents, i.e. oil-soluble non-ionic, water-soluble non-ionic and water-soluble cationic ones, and a saccharide compound such as glucose. By virtue of the unique formulation, the composition has a greatly extended pot-life suitable for coating works of, for example, steel rods and pipes by the dip coating method.Type: GrantFiled: July 27, 1987Date of Patent: November 29, 1988Assignees: Zairyo Kagaku Kenkyusho Co., Ltd., Mitsui Engineering & Shipbuilding Co., Ltd.Inventors: Kiyoshi Suzuki, Toshiaki Murata, Isao Nakata

Patent number: 4684296Abstract: Uniform flow of gas flowing in a cylinder having inner diameter larger than that of a pipeline is introduced through a funnelform reducer into the inlet of the pipeline, where uniform flow of gas turned to a spiral gas stream by bringing to the mean gas stream velocity faster than 20 meter per second there. When solid particles are introduced into the spiral gas strem zone, they are transported to the outlet of the pipeline. A compressed gas layer is formed along the inside wall of the pipeline by the spiral motion of gas stream, and the layer prevents the direct contact of the solid particles to the inside wall of the pipeline which causes the erosion of the pipeline. As the center part of the cross section of the pipeline becomes very low pressure, especially along the axis of the pipeline, solid particles containing or accompanying volatile matters are desiccated or concentrated as a result of the evaporation of volatile matters while being transported in the pipeline.Type: GrantFiled: October 24, 1986Date of Patent: August 4, 1987Assignee: Kiyoshi HoriiInventors: Kiyoshi Horii, Toshiaki Murata
