Publication number: 20170282172Abstract: Provided is an oxidation reactor capable of oxidizing hydrocarbons with both reaction efficiency and energy efficiency. The oxidation reactor according to the present invention includes a liquid inlet channel, a gas inlet channel, a gas-liquid mixing unit, and a flow reactor. Through the liquid inlet channel, a liquid containing a reaction substrate hydrocarbon is introduced. Through the gas inlet channel, a gas containing oxygen and ozone is introduced. The gas-liquid mixing unit mixes the liquid introduced from the liquid inlet channel with the gas introduced from the gas inlet channel. In the flow reactor, an oxidation catalyst is immobilized or packed. The gas-liquid mixing unit houses, in its channel, a mobile particle which is capable of rotating and/or moving to mix the liquid with the gas to thereby form a gas-liquid slug flow. The gas-liquid slug flow is introduced into the flow reactor.Type: ApplicationFiled: August 7, 2015Publication date: October 5, 2017Applicants: OSAKA PREFECTURE UNIVERSITY PUBLIC CORPORATION, DAICEL CORPORATIONInventors: Akinori MUTO, Yoshiyuki MURAI, Takamasa SUZUKI, Ichiro TAKASE

Patent number: 6940706Abstract: It is acknowledged that an electric double layer capacitor is markedly superior in power density and cycle characteristics to a secondary battery. However, a higher energy density is required to apply it to a power supply of hybrid vehicle, electric vehicle or the like. The present inventors have found that a carbonaceous material containing copper or a compound of copper exhibits excellent characteristics as an electrode material for capacitor and can realize a capacitor having a large capacity. In the electrode material and the capacitor, copper or a compound of copper exists in the amount of 0.8 to 30 parts by weight calculated on the metal basis based on 100 parts by weight of the carbonaceous material, particularly preferably.Type: GrantFiled: December 1, 2000Date of Patent: September 6, 2005Assignee: Kanebo Ltd.Inventors: Yusaku Sakata, Akinori Muto, Norimasa Yamada, Azhar Uddin, Masaru Takei, Kenji Kojima, Satoshi Ibaraki, Chisato Marumo
