The Si/Al ratio did not affect on the surface area nor the crystallinity. However, the acidity of the zeolite decreased with an increasing ratio of Si/Al. The acid strength distribution of the zeolite was compared with those of amorphous silica-alumina and HY type zeolite. The results indicate that HZSM-5 has many strong acid sites which could be effective for the disproportionation of aromatic hydrocarbons. An o-xylene isomerization reaction was carried out for the HZSM-5 zeolites in a fixed type reactor. The catalytic activity of the zeolites was greater than that of amorphous silica-alumina, but no activity difference was observed among the different zeolites. Unlike the isomerization over silica-alumina catalyst, 1, 2, 4- and 1, 3, 5- trimethybenzenes could not be detected in the product streams. The result suggests that the micropore of the zeolite, composed  of a 10 membered oxygen rings, \nprevents a bulky compound such as trimethylbenzene from being produced.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0451212X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040363","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"573","subitem_subject_scheme":"NDC"}]},"item_7_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, Takashige","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"劉, 興允","creatorNameLang":"zh-tw"},{"creatorName":"LIU, Xing Yun","creatorNameLang":"en"}]}]},"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":"AN00040363_v26_p119-124.pdf","filesize":[{"value":"582.3 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040363_v26_p119-124.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/4554/files/AN00040363_v26_p119-124.pdf"},"version_id":"02178db2-4112-45be-be69-b40a6ad75262"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ZSM-5ゼオライトの触媒活性におよぼすSi/Al比の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ZSM-5ゼオライトの触媒活性におよぼすSi/Al比の影響","subitem_title_language":"ja"},{"subitem_title":"Effect of Si/Al ratio on catalytic activioty of ZSM-5 zeolite","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5345"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-09"},"publish_date":"2015-06-09","publish_status":"0","recid":"4554","relation_version_is_last":true,"title":["ZSM-5ゼオライトの触媒活性におよぼすSi/Al比の影響"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T04:58:38.572642+00:00"}
