As the pre-treating of the biomass, hydrothermal reaction of the bagasse or molasses using only water or acid-added water was carried out, and the suitable conditions, product yields and the effect of using acid were clarified. The effect of intermediate species obtained in the pre-treating step on the species and yields of the product in the catalytic conversion step was also investigated. As a results, it was concluded that BTX was mainly obtained from levulinic acid, mixture of mono- and di-aromatic chemicals from 5-hydroxymethylfurfural or glycolaldehyde, and mainly di-aromatic chemicals and coke from mono-saccharides. For enhancing BTX yields and reducing coke formation, it was found that the diffusion of the intermediates into zeolite pores was important and the unsteady-state reaction operation was an effective reaction method.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_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_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"519","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"21310056"}]},"item_8_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":"筒井, 俊雄","creatorNameLang":"ja"},{"creatorName":"TSUTSUI, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"12582","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000060133097","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":"21310056seika.pdf","filesize":[{"value":"264.2 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"21310056seika.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/5094/files/21310056seika.pdf"},"version_id":"b6b43593-6fc6-470d-b0b5-2c35733efcdb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"省資源技術","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"再生可能資源活用","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"バイオマス資源から化学原料を製造するバイオファクトリー反応技術の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"バイオマス資源から化学原料を製造するバイオファクトリー反応技術の研究","subitem_title_language":"ja"},{"subitem_title":"Investigation on bio-factory reaction technology for manufacturing fundamental chemicals from biomass resources","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["79"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-12-22"},"publish_date":"2014-12-22","publish_status":"0","recid":"5094","relation_version_is_last":true,"title":["バイオマス資源から化学原料を製造するバイオファクトリー反応技術の研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-23T02:18:12.365383+00:00"}
