The deactivation constant over SSZ-24 was the highest among the zeolites used in the study. Furthermore, when the ratio between the molecular size of e-caprolactam (CL) and the pore size of zeolite was unity, the deactivation constant was maximum over the zeolites at similar acidity. These results indicate that since CL produced on the active sites cannot diffuse from the micropores, the CL reacts to form coke or its precursor over a long residence time. The pore size of the zeolite is the main controlling factor of catalyst deactivation during the Beckmann rearrangement.","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":"石油学会","subitem_publisher_language":"ja"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1627/jpi.49.301","subitem_relation_type_select":"DOI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人石油学会","subitem_rights_language":"ja"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349273X","subitem_source_identifier_type":"EISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11590615","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"568","subitem_subject_scheme":"NDC"},{"subitem_subject":"571","subitem_subject_scheme":"NDC"}]},"item_6_subject_20":{"attribute_name":"NIIsubject","attribute_value_mlt":[{"subitem_subject":"化学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"プロセス工学・化学工学","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":"高橋, 武重","creatorNameLang":"ja"},{"creatorName":"Takahashi, Takeshige","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3495","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020041543","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"仲西, 真由美","creatorNameLang":"ja"},{"creatorName":"Nakanishi, Mayumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"86362","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"甲斐, 敬美","creatorNameLang":"ja"},{"creatorName":"Kai, Takami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3496","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000000177312","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"jpa_2006_49_6.pdf","filesize":[{"value":"767.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jpa_2006_49_6.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/6798/files/jpa_2006_49_6.pdf"},"version_id":"6e364cec-04e6-407d-9294-541dfd0c76bf"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Beckmann rearrangement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cyclohexanone oxime","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Zeolite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Caprolactam selectivity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Catalyst deactivation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pore size effect","subitem_subject_language":"en","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":"ゼオライトによる気相ベックマン転位反応の活性劣化に及ぼす細孔径の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ゼオライトによる気相ベックマン転位反応の活性劣化に及ぼす細孔径の影響","subitem_title_language":"ja"},{"subitem_title":"Effect of Micropore Size on Catalyst Deactivation in Vapor Phase Beckmann Rearrangement over Zeolites","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["67"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-02-06"},"publish_date":"2015-02-06","publish_status":"0","recid":"6798","relation_version_is_last":true,"title":["ゼオライトによる気相ベックマン転位反応の活性劣化に及ぼす細孔径の影響"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T05:05:25.337171+00:00"}
