Patent number: 8088946Abstract: The present invention provides: a palladium-containing supported catalyst which is used for producing an ?,?-unsaturated carboxylic acid from an olefin or an ?,?-unsaturated aldehyde in high selectivity; a method for manufacturing the catalyst; and a method for producing an ?,?-unsaturated carboxylic acid in high selectivity. In particular, the present invention resides in a method for manufacturing a palladium-containing supported catalyst for producing an ?,?-unsaturated carboxylic acid from an olefin or an ?,?-unsaturated aldehyde, comprising the step of reducing palladium oxide contained in a catalyst precursor wherein at least the palladium oxide is supported on a carrier. By using such a palladium-containing supported catalyst, an ?,?-unsaturated carboxylic acid is produced through liquid-phase oxidation of an olefin or an ?,?-unsaturated aldehyde with molecular oxygen.Type: GrantFiled: November 14, 2005Date of Patent: January 3, 2012Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Yoshiyuki Himeno, Wataru Ninomiya, Ken Ooyachi

Patent number: 7651074Abstract: This invention concerns an apparatus and a method for producing carbonated water capable of obtaining high concentration carbonated water effectively. Carbon dioxide gas is passed through a first carbon dioxide gas dissolver composed of a membrane module to be dissolved in water and the carbonated water passing through the first carbon dioxide gas dissolver is passed through a static mixer, which is a second carbon dioxide gas dissolver. Consequently, a high concentration carbonated water can be obtained remarkably, effectively and easily with a simpler structure than conventionally.Type: GrantFiled: September 25, 2008Date of Patent: January 26, 2010Assignees: Mitsubishi Rayon Co., Ltd., Mitsubishi Rayon Engineering Co., Ltd.Inventors: Ken Ooyachi, Hiroki Sakakibara, Hiroshi Tasaka, Masaaki Satou, Masanori Itakura, Katsuya Sanai

Publication number: 20080274248Abstract: Hot water is pumped by a suction pump and introduced into a carbon dioxide (CO2) gas dissolver through solution flow rate adjusting means and then poured into a bath. The CO2 is introduced into the CO2 gas dissolver through gas flow rate adjusting means, and the quantity of bubbles in an artificial carbonated spring in a take-out pipe is measured. The solution and gas flow rate adjusting means are controlled via a control device using a relationship expression between a preliminarily set quantity of bubbles and carbon dioxide concentration to obtain a desired concentration of carbon dioxide gas in the carbonated spring. Since the carbon dioxide gas flow control means is provided between the carbon dioxide gas dissolver and a carbon dioxide gas supply source, a high concentration carbonated spring can always be manufactured, even if the pressure of supplied carbon dioxide gas changes or membrane permeation changes.Type: ApplicationFiled: June 27, 2008Publication date: November 6, 2008Applicant: MITSUBISHI RAYON CO., LTDInventors: Hiroshi Sakakibara, Ken Ooyachi, Hiroshi Tasaka
