This system can produce the hydrogen-rich water gas without any by-products. To evaluate bamboo as the second stage gasification resource, carbonization of moso bamboo and gasification of its char were carried out using the small laboratory plant. Carbonization of bamboo from 600 ℃ to 800 ℃ produced suitable chars as the source for steam gasification. The gasification of these bamboo chars produced clean hydrogen rich gases without any by-products. The wood gas from the carbonization had sufficient HHV available for fuels as the heating source in gasification. The gasification rate was increased remarkably with raising the gasification temperature. The lower gasification temperature induced water gas shift reaction, which leads to change the water gas composition. Raising the gasification temperature also increased specific HHV and decreased gas yield. Raising steam supply rate decreased specific HHV and CO gas yield whereas H2 and CO2 gas yields were increased. In these cases, water-gas shift reaction acted an important rule. The reaction rates of water gas reaction (k1), water-gas shift reaction (k2) and Boudouard reaction (k3) are calculated and the values well explain the gas composition produced under various gasification condition.","subitem_description_type":"Abstract"},{"subitem_description":"二段階ガス化は、１段目のバイオマスの炭化と２段目の炭化物の水蒸気ガス化より構成されている。このシステムは、副産物の生成を抑えて、水素リッチな水性ガスを生成することができる。２段目のガス化へのタケの利用を検討するために、モウソウダケの炭化とその炭化物のガス化を小型ラボプラントで行った。水蒸気ガス化に適した炭化物は、600℃から800℃で行われたタケの炭化にて生成された。これらの炭化物を用いたガス化では、副生成物がない水素リッチガスが生成された。炭化時に生成される木ガスは、ガス化の熱源の燃料として十分な高位発熱量（HHV）を有していた。ガス化速度は、ガス化温度の上昇と共に顕著に増加した。ガス化温度の低下は水性ガスシフト反応を誘導し、水性ガス組成の変化を生じる。また、ガス化温度の上昇は、生成ガス高位発熱量を増加させ、ガス生成量を減少させた。水蒸気供給速度の上昇は、生成ガス高位発熱量と、COガスの生成量を減少させたが、H2とCO2ガスの生成量を増加させた。これらの反応では、水性ガスシフト反応が重要な役割を果たす。計算によって求めた水性ガス反応（k1）、水性ガスシフト反応（k2）、ブードア反応（k3）の反応速度は、様々なガス化条件下で生成されたガス組成によく合致している。","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162539","nameIdentifierScheme":"WEKO"}],"names":[{"name":"加藤, 喜明"}]},{"nameIdentifiers":[{"nameIdentifier":"162540","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小島, 康夫"}]},{"nameIdentifiers":[{"nameIdentifier":"162541","nameIdentifierScheme":"WEKO"}],"names":[{"name":"尹, 承洛"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学農学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183393","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03858634","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kato, Yoshiaki"}],"nameIdentifiers":[{"nameIdentifier":"162536","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kojima, Yasuo"}],"nameIdentifiers":[{"nameIdentifier":"162537","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoon, Seung-Lak"}],"nameIdentifiers":[{"nameIdentifier":"162538","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-20"}],"displaytype":"detail","filename":"66(2)_131-139.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"66(2)_131-139.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28288/files/66(2)_131-139.pdf"},"version_id":"02a708dc-213f-4760-a292-442ddebf992b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"moso bamboo","subitem_subject_scheme":"Other"},{"subitem_subject":"char","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrogen-rich gas","subitem_subject_scheme":"Other"},{"subitem_subject":"steam gasification","subitem_subject_scheme":"Other"},{"subitem_subject":"モウソウダケ","subitem_subject_scheme":"Other"},{"subitem_subject":"炭化物","subitem_subject_scheme":"Other"},{"subitem_subject":"水素リッチガス","subitem_subject_scheme":"Other"},{"subitem_subject":"水蒸気ガス化","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Hydrogen-rich gas production by steam gasification of bamboo char","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Hydrogen-rich gas production by steam gasification of bamboo char"},{"subitem_title":"Hydrogen-rich gas production by steam gasification of bamboo char","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1589"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-04-07"},"publish_date":"2014-04-07","publish_status":"0","recid":"28288","relation_version_is_last":true,"title":["Hydrogen-rich gas production by steam gasification of bamboo char"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:15.981096+00:00"}
