Patent number: 8696773Abstract: In a reforming apparatus, for use in a fuel cell, for reforming a raw fuel into a hydrogen-rich reformed gas, a reformer generates the reformed gas from the raw fuel. A shift reactor reduces carbon monoxide contained in the reformed gas through a shift reaction. A selective oxidation unit reduces the carbon monoxide contained in the reformed gas that has passed through the shift reactor by performing selective oxidation on the carbon monoxide. A reforming reaction tube houses linearly the reformer, the shift reactor and the selective oxidation unit in this order.Type: GrantFiled: March 27, 2012Date of Patent: April 15, 2014Assignee: JX Nippon Oil & Energy CorporationInventors: Akira Fuju, Masataka Kadowaki, Kazumi Kobayashi, Kazuaki Nakajima, Yasushi Sato, Ken Samura

Patent number: 8690972Abstract: A hydrogen production system (X1) according to the present invention includes a reforming apparatus (Y1) having a vaporizer (1) and a reforming reactor (2), and a PSA apparatus (5). In the vaporizer (1) a mixed material (hydrocarbon-based material, water, and oxygen) is heated and vaporized. In the reforming reactor (2), steam reforming reaction and partial oxidation reaction of the hydrocarbon-based material take place at a time, so that reformed gas (containing hydrogen) is led out from the vaporized mixed material. In the PSA apparatus (5), the reformed gas is introduced into an adsorption tower loaded with an adsorbing agent, so that an unnecessary component in the gas is adsorbed by the adsorbing agent and hence hydrogen-rich gas is led out of the tower, while the unnecessary component is desorbed from the adsorbing agent, so that hydrogen-containing desorbed gas that contains the unnecessary component and hydrogen remaining in the tower is discharged out of the tower.Type: GrantFiled: July 7, 2005Date of Patent: April 8, 2014Assignee: Sumitomo Seika Chemicals Co., Ltd.Inventors: Yoshinori Takata, Masanori Miyake, Toshihiko Sumida

Patent number: 8641790Abstract: A method of increasing the hydrogen/carbon monoxide (H2/CO) ratio in a syngas stream derived from a carbonaceous fuel including coal, brown coal, peat, and heavy residual oil fractions, preferably coal. The fuel-derived syngas stream is divided into at least two sub-streams, one of which undergoes a catalytic water shift conversion reaction. The so-obtained converted sub-stream is combined with the non-converted sub-stream(s) to form a second syngas stream with an increased H2/CO ratio. The method of the present invention can provide a syngas with a H2/CO ratio more suitable for efficient hydrocarbon synthesis carried out on a given catalyst, such as in one or more Fischer-Tropsch reactors, as well as being able to accommodate variation in the H2/CO ratio of syngas formed from different qualities of feedstock fuels.Type: GrantFiled: December 29, 2005Date of Patent: February 4, 2014Assignee: Shell Oil CompanyInventors: Joachim Ansorge, Scott Bilton, Hendrik Jan Van Der Ploeg, Arold Marcel Albert Routier, Cornelis Jacobus Smit
