Patent number: 11918986Abstract: There is provided an exhaust gas purification device that shows a high HC removal performance under a condition in which a rich air-fuel mixture is introduced. The exhaust gas purification device includes a substrate, a first catalyst layer, and a second catalyst layer. The substrate includes an upstream end and a downstream end. The first catalyst layer is disposed on a surface of the partition wall in an upstream region including the upstream end of the substrate. The second catalyst layer is disposed inside the partition wall in a downstream region including the downstream end of the substrate. The first catalyst layer contains a first metal catalyst and alumina-zirconia composite oxide. The second catalyst layer contains a second metal catalyst.Type: GrantFiled: May 24, 2022Date of Patent: March 5, 2024Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, CATALER CORPORATIONInventors: Koji Sugiura, Takeshi Hirabayashi, Akemi Satou, Keisuke Murawaki, Takaya Ota, Masatoshi Ikebe, Kohei Takasaki, Takeshi Morishima

Patent number: 11679379Abstract: The exhaust gas purification device includes a substrate, a first catalyst layer, and a second catalyst layer. The substrate includes an upstream end, a downstream end, and a porous partition wall defining a plurality of cells extending between the upstream end and the downstream end. The plurality of cells include an inlet cell opening at the upstream end and sealed at the downstream end, and an outlet cell adjacent to the inlet cell sealed at the upstream end and opening at the downstream end. The first catalyst layer is disposed on a surface of the partition wall in an upstream region. In a downstream region, the second catalyst layer is disposed inside the partition wall, and a second catalyst-containing wall including the partition wall and the second catalyst layer has a porosity of 35% or more.Type: GrantFiled: May 2, 2022Date of Patent: June 20, 2023Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, CATALER CORPORATIONInventors: Koji Sugiura, Takeshi Hirabayashi, Akemi Satou, Keisuke Murawaki, Takaya Ota, Masatoshi Ikebe, Kohei Takasaki, Takeshi Morishima

Patent number: 11473472Abstract: An exhaust gas control apparatus includes a honeycomb substrate and an inlet cell-side catalyst layer. The honeycomb substrate includes a porous partition wall that defines a plurality of cells extending from an inlet-side end face to an outlet-side end face. The cells include an inlet cell and an outlet cell that are adjacent to each other with the partition wall therebetween. The inlet cell is open at its inlet-side end and is sealed at its outlet-side end. The outlet cell is sealed at its inlet-side end and is open at its outlet-side end. The inlet cell-side catalyst layer is provided on a surface on the inlet cell side of the partition wall and extends from an inlet-side end of the partition wall. Porosity of the inlet cell-side catalyst layer is in a specific range.Type: GrantFiled: April 15, 2021Date of Patent: October 18, 2022Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, CATALER CORPORATIONInventors: Koji Sugiura, Hiromasa Nishioka, Naoto Miyoshi, Akemi Satou, Keisuke Murawaki, Masatoshi Ikebe, Takaya Ota, Ryota Nakashima, Hirotaka Ori

Patent number: 8551908Abstract: An exhaust gas purification catalyst includes: a lower catalyst layer that contains a ceria-zirconia mixed oxide having 50 to 70 mass % of CeO2 and 5 mass % or more of Pr2O3 and carries at least one of Pt and Pd; and an upper catalyst layer that contains at least zirconia and carries at least Rh, wherein the total amount of CeO2 per liter of the carrier base is 15 to 30 g. Because the amount of CeO2 is small, formation of H2S is suppressed and a high capability of adsorbing and releasing oxygen is brought out in spite of the small amount of CeO2.Type: GrantFiled: June 26, 2009Date of Patent: October 8, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Akemi Satou, Masahiko Takeuchi, Keizo Hiraku, Yusuke Kawamura, Takahiro Fujiwara, Tadashi Suzuki, Naoki Takahashi
