Three different catalyst surfaces were prepared as oxidized (S_\u003cOX\u003e), reduced (S_\u003cred\u003e) and treated with ethylene (S_\u003cIn\u003e) on which the stable intermediate (In) were accumulated, compared among the effective diffusivities of the gases (De). The molecular diffusion process was achieved with N_2 and He for all the surfaces and at all the gases except O_2 on S_\u003cred\u003e. The De’s of CO_2, C_2H_4 and C_3H_6 on S_\u003cIn\u003e. were higher than those on S_\u003cred\u003e, suggesting the contribution of surface diffusion on S_\u003cIn\u003e. (In) works to increase the amount of isolated surface oxygen species which is available for the adsorption sites of CO_2, C_2H_4 and C_3H_6. This phenomena causes localization of the gases on the surface and change in their surface diffusion rate.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "北見工業大学"}]}, "item_2_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tohru, KANNO"}], "nameIdentifiers": [{"nameIdentifier": "33339", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Masayoshi, KOBAYASHI"}], "nameIdentifiers": [{"nameIdentifier": "33340", "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": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "20-2-2.pdf", "filesize": [{"value": "5.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 5000000.0, "url": {"label": "20-2-2.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/6637/files/20-2-2.pdf"}, "version_id": "b9de4f0d-afae-42b2-bf32-2668070592d9"}]}, "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": "Gas Diffusion Process in a Silver Catalyst Used for Ethylene Oxidation*", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Gas Diffusion Process in a Silver Catalyst Used for Ethylene Oxidation*"}]}, "item_type_id": "2", "owner": "1", "path": ["41"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/6637", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-04-09"}, "publish_date": "2007-04-09", "publish_status": "0", "recid": "6637", "relation": {}, "relation_version_is_last": true, "title": ["Gas Diffusion Process in a Silver Catalyst Used for Ethylene Oxidation*"], "weko_shared_id": 3}
