Title (EN) HONEYCOMB FILTER
(FR) FILTRE EN NID D'ABEILLES
(JA) ハニカムフィルタ
Abstract:
(EN) This honeycomb filter is used to capture fine particles, and is provided with wall parts (13) comprising a base material having, as constituent components, a ceria-zirconia composite oxide and an inorganic binder. The wall parts (13) have a peak in the range of pore sizes from 0.01 µm to less than 1 µm, and a peak in the range of pore sizes of 1-50 µm inclusive, in a pore size distribution which is measured using the mercury penetration method, and in which the pore size and the log differential pore volume as are set as the horizontal axis and the vertical axis respectively.
(FR) La présente invention concerne un filtre en nid d'abeilles utilisé pour capturer des particules fines et muni de parties (13) de paroi comprenant un matériau de base comportant, en tant que constituants, un oxyde composite d'oxyde de cérium-oxyde de zirconium et un liant inorganique. Les parties (13) de paroi présentent un pic dans la plage de dimensions des pores compris entre 0,01 µm et moins de 1 µm, et un pic dans la plage de dimensions des pores compris entre 1 et 50 µm inclus, dans une distribution de dimensions des pores mesurée à l'aide du procédé de pénétration de mercure et dans laquelle la dimension des pores et le volume de pore différentiel logarithmique sont définis comme l'axe horizontal et l'axe vertical respectivement.
(JA) ハニカムフィルタは、微粒子の捕集に用いられ、セリア-ジルコニア複合酸化物と無機バインダを構成成分とする基材からなる壁部(13)を備える。壁部(13)は、水銀圧入法で測定される気孔径及びlog微分細孔容積をそれぞれ横軸及び縦軸とする気孔径分布において、気孔径0.01μm以上1μm未満の範囲にピークを有するとともに、気孔径1μm以上50μm以下の範囲にピークを有する。
