Patent number: 7923406Abstract: A support for a fuel reforming catalyst includes aluminum (Al); and aluminum oxide (Al2O3) encapsulating the aluminum, wherein a total volume of micropores and mesopores is in the range of 0.1 to 1.0 ml/g per unit mass, and a volume of macropores is in the range of 0.4 to 1.2 ml/g per unit mass, and a method of preparing the same. The support has excellent heat transfer characteristics due to its high thermal conductivity and excellent mass transfer characteristics because the micropores, mesopores, and macropores exist in a proper ratio. Accordingly, if the support is used for a supported catalyst that is used in a reaction, in which the reaction rate is controlled by heat transfer and mass transfer, such as a fuel reforming reaction, the activity of the catalyst is enhanced. In addition, the support can be easily formed as desired due to its high mechanical strength.Type: GrantFiled: January 23, 2006Date of Patent: April 12, 2011Assignee: Samsung SDI Co., Ltd.Inventors: Yulia Potapova, Soon-ho Kim, Hyun-chul Lee

Patent number: 7850937Abstract: A catalytic system for CO removal includes a gold (Au) catalyst and a co-catalyst in contact with an aqueous phase, and a fuel cell system using the same. The catalytic system is relatively very simple compared to a common CO removal system, and can highly efficiently remove CO at low temperature without side reaction. In addition, water contacted in the catalytic system can act as a buffer for the rise and fall of temperature, and thus, can cope with an accidental temperature change. Further, the catalytic system shows a low operation temperature, and thus, can be operated over a broad operation range considering the activity and/or selectivity of the gold catalyst, etc.Type: GrantFiled: January 18, 2006Date of Patent: December 14, 2010Assignee: Samsung SDI Co., Ltd.Inventors: Hyun-chul Lee, Soon-ho Kim, Yulia Potapova, Eun-duck Park, Eun-yong Ko

Patent number: 7833934Abstract: A hydrocarbon reforming catalyst, a method of preparing the same, and a fuel processor including the same includes the hydrocarbon reforming catalyst having an active catalyst component impregnated in a oxide carrier and a thermally conductive material having higher thermal conductivity than that of the oxide carrier, the method of preparing the same, and a fuel processor including the same. The hydrocarbon reforming catalyst has excellent catalytic activity and thermal conductivity, and thus can easily transfer heat required in a hydrocarbon reforming reaction. Accordingly, by using the hydrocarbon reforming catalyst above, a high hydrogen production rate can be obtained.Type: GrantFiled: November 29, 2006Date of Patent: November 16, 2010Assignee: Samsung SDI Co., Ltd.Inventors: Yulia Potapova, Soon-ho Kim, Doo-hwan Lee, Hyun-chul Lee

Patent number: 7625429Abstract: A zeolite adsorbent for desulfurization and a method of preparing the same. More particularly, a zeolite adsorbent for desulfurization in which the relative crystallinity of Y zeolite that is ion exchanged with Ag is 45% to 98%, and a method of preparing the same. The zeolite adsorbent for desulfurization has excellent crystallinity over the known zeolite adsorbent for desulfurization, and thus has better performance of adsorbing sulfur compounds though it contains less Ag. Accordingly, when the sulfur compounds of a fuel gas are removed by employing the zeolite adsorbent for desulfurization, a desulfurizing device that is bettereven with less cost can be constructed.Type: GrantFiled: January 23, 2006Date of Patent: December 1, 2009Assignee: Samsung SDI Co., Ltd.Inventors: Soon-ho Kim, Hyun-chul Lee, Yulia Potapova, Eun-duck Park, Eun-yong Ko

Publication number: 20070180767Abstract: A non-pyrophoric shift reaction catalyst includes an oxide carrier impregnated with platinum (Pt) and cerium (Ce). The non-pyrophoric shift reaction catalyst may be prepared by uniformly mixing a platinum precursor, a cerium precursor, and an oxide carrier in a dispersing medium to obtain a mixture; drying the mixture; and calcining the dried mixture. The shift reaction catalyst having a non-pyrophoric property has an excellent reaction activity even at a low temperature and can efficiently remove carbon monoxide in fuel.Type: ApplicationFiled: November 29, 2006Publication date: August 9, 2007Applicant: Samsung SDI Co., Ltd.Inventors: Hyun-chul Lee, Soon-ho Kim, Doo-hwan Lee, Yulia Potapova, Ok-young Lim, Eun-duck Park, Eun-yong Ko
