The catalyst particles around the bubbles should contact the gases containing a high concentration of the reactants.\nTherefore, the effect of the catalysts around the bubbles is very important for estimating the conversion and selectivity in the reactor. In\norder to study the role of these catalysts, the hydrogenation of carbon dioxide was carried out in a fluidized catalyst bed. Based on the \nresults, the amount of the catalyst that was effective for the reaction was calculated. In addition, the shape of the bubbles ascending in the \nfluidized catalyst bed was observed using a fast X-ray computer tomography (CT) scanner. The structure of the bubbles in the fluidized \ncatalyst bed was very complicated and the surface area of the bubbles was much greater than the obtained when assuming spherical \nshaped bubble. By assuming that effective catalysts existed around the bubbles, the thickness of catalyst layer was obtained. Finally, the \n3-dimensional images of the catalyst layers around the bubbles were reconstructed.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.cej.2006.06.017","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13858947","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11523425","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"464","subitem_subject_scheme":"NDC"}]},"item_6_subject_20":{"attribute_name":"NIIsubject","attribute_value_mlt":[{"subitem_subject":"生化学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_6_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kai, Takami","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okada, Norihide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Baba, Manabu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahashi, Takeshige","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Misawa, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ion, Tiseanuc","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ichikawa, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"CEJ2007.pdf","filesize":[{"value":"188.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CEJ2007.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/3797/files/CEJ2007.pdf"},"version_id":"5b3d1e5e-dc87-4b32-a553-6172648680a6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fluidization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fluidized bed","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Catalytic reaction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Reactor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tomography","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Bubble","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Structure of effective catalyst layers around bubbles in a fluidized catalyst bed","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Structure of effective catalyst layers around bubbles in a fluidized catalyst bed","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["67"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-09-13"},"publish_date":"2007-09-13","publish_status":"0","recid":"3797","relation_version_is_last":true,"title":["Structure of effective catalyst layers around bubbles in a fluidized catalyst bed"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T05:04:40.331599+00:00"}
