The entire decomposition or absorption curves, however, could not been described by any simple kinetic equations appearing in the literature. The present paper describes verification of plausible kinetic equations reproducing the observed absorption curves, assuming a reaction mechanism consisting of a progressive removal of hydrogen atoms according to CH4(g) →CH3(a)→ CH2(a)→ CH(a)→ C(a) and its modification including carbon segregation schemes by solving a set of kinetic equations by means of finite difference method, by taking into account of ab-initio calculations of potential energy surfaces by Gaussian 03. It was found that a step-by-step H-deletion model could not generate the experimentally observed absorption curves, but they could be reproduced quite well in the whole reaction range by a modified reaction scheme assuming coagulation of a carbon residue like CH2(a) or CH(a) to carbonaceous deposits, described as CH4(g) →k1 CH3(a)→ k2 CH(a) →k3 C-deposits. It was concluded that the final third step (with a rate constant of k3) governs the overall absorption reactivity (methane consumption beyond 90%) of the materials.", "subitem_description_type": "Abstract"}]}, "item_3_description_40": {"attribute_name": "資源タイプ(DSpace)", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_3_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "58765", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Watanabe, Kuniaki"}]}, {"nameIdentifiers": [{"nameIdentifier": "58766", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Shu, W."}]}, {"nameIdentifiers": [{"nameIdentifier": "58767", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Matsuyama, Masao"}]}]}, "item_3_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15099/00006495", "subitem_identifier_reg_type": "JaLC"}]}, "item_3_publisher_33": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "富山大学水素同位体科学研究センター"}]}, "item_3_source_id_10": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11841872", "subitem_source_identifier_type": "NCID"}]}, "item_3_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0916-8486", "subitem_source_identifier_type": "ISSN"}]}, "item_3_version_type_16": {"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": "松山, 政夫"}], "nameIdentifiers": [{"nameIdentifier": "58762", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "渡辺, 国昭"}], "nameIdentifiers": [{"nameIdentifier": "58763", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "洲, 亘"}], "nameIdentifiers": [{"nameIdentifier": "58764", "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": "2016-02-17"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "annual_report26-1.pdf", "filesize": [{"value": "193.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 193200.0, "url": {"label": "annual_report26-1.pdf", "url": "https://toyama.repo.nii.ac.jp/record/6501/files/annual_report26-1.pdf"}, "version_id": "106c7aa8-b604-4f27-af99-5237d6cac1a1"}]}, "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": "ジルコニウム合金上のメタン分解動力学", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "ジルコニウム合金上のメタン分解動力学"}]}, "item_type_id": "3", "owner": "3", "path": ["806"], "permalink_uri": "https://doi.org/10.15099/00006495", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-10-03"}, "publish_date": "2007-10-03", "publish_status": "0", "recid": "6501", "relation": {}, "relation_version_is_last": true, "title": ["ジルコニウム合金上のメタン分解動力学"], "weko_shared_id": -1}
