Patent number: 8551416Abstract: A method and system for recovering CO2 from gasification gas, prevents the recovered CO2 from being contaminated with COS, without repeating cooling and heating operations and without increasing the steam consumption. Gasification gas being produced in a gasifier 10 and containing CO, CO2, COS and H2S is subjected to dust removal in a scrubber 20. Then, a part of the gas is subjected to a CO shift reaction, in which CO is converted into CO2, in a CO shift reactor 30. In one embodiment, part of the gasification gas is not subjected to the CO shift reaction by means of a bypass 34, and is mixed with the gas after the CO shift reaction. Thereby, the temperature of the mixture gas is set at 180° C. to 300° C., and COS in the mixture gas is converted into H2S in a COS converter 40.Type: GrantFiled: October 22, 2009Date of Patent: October 8, 2013Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Fumiaki Sato, Shinji Ogino, Motonari Aihara, Yudai Kato, Kazuo Ishida, Seiji Kakesako

Patent number: 8477413Abstract: An optical element for reflecting solar light has excellent weather resistance, and furthermore, a high reflectance in a wide band. When solar light enters an optical element (OE), light (L1) in a short wavelength band among the solar light is reflected by a dielectric multilayer film (DF). Other light (L2) in longer wavelength bands are passed through the dielectric multilayer film (DF), then a base material (SS), and reflected by a metal deposition film (MV) to pass through the base material (SS) and the dielectric multilayer film (DF). Thus, high reflectance in a wide band is ensured.Type: GrantFiled: October 27, 2008Date of Patent: July 2, 2013Assignee: Konica Minolta Opto, Inc.Inventors: Nobuyoshi Mori, Kazuo Ishida, Takuji Hatano, Setsuo Tokuhiro
