In the first stage, thermal cracking of high density polyethylene (HDPE) was carried out at 450-500℃. Yields of the cracked oil from HDPE were 79% at 450℃ and 88% at 500℃, respectively. Hydrocarbons of C7-C20 were the predominant products in the cracked oil. Higher hydrocarbons (>C20) increased with increasing reaction temperature. In the second stage, in order to obtain lower alkenes (mainly C_2H_4 and C_3H_6), the catalytic cracking of the thermally-cracked oil obtained in the first stage was carried out using a HZSM-5 catalyst at 600℃ in N_2 and CO_2 atmospheres. Since the cracked oil was difficult to handle, n-C_<16>H_<34>, which was a representative product in the thermal cracking of HDPE, was employed as a model compound. HZSM-5 catalyst increased the C1-C4 gas yield to 50% and C_2H_4 + C_3H_6 yield to 12% in N_2 atmosphere. On the other hand, in CO_2 atmosphere the gas yield reached 61% and C_2H_4 + C_3H_6 yield reached 30%, respectively. Addition of CO_2 promoted the catalytic cracking of n-C_<16>H_^<34> with HZSM-5 to give C_2H_4 + C_3H_6.","subitem_description_type":"Other"}]},"item_10_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"28182","nameIdentifierScheme":"WEKO"}],"names":[{"name":"池永, 直樹"}]},{"nameIdentifiers":[{"nameIdentifier":"28183","nameIdentifierScheme":"WEKO"}],"names":[{"name":"宮村, 佳成"}]},{"nameIdentifiers":[{"nameIdentifier":"28184","nameIdentifierScheme":"WEKO"}],"names":[{"name":"鈴木, 俊光"}]}]},"item_10_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"関西大学工学部"}]},"item_10_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00046916","subitem_source_identifier_type":"NCID"}]},"item_10_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04532198","subitem_source_identifier_type":"ISSN"}]},"item_10_version_type_17":{"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":"Ikenaga, Naoki"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Miyamura, Yoshinari"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Toshimitsu"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-20060321-05.pdf","filesize":[{"value":"745.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20060321-05.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/11783/files/KU-1100-20060321-05.pdf"},"version_id":"343037c9-9180-4632-90f5-8253dda6e639"}]},"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":"Promoting Effext of CO2 on the Degradation of Polyethylene to Ethylene and Propylene Over HZSM-5 Catalyst","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Promoting Effext of CO2 on the Degradation of Polyethylene to Ethylene and Propylene Over HZSM-5 Catalyst"}]},"item_type_id":"10","owner":"1","path":["1626"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-26"},"publish_date":"2018-01-26","publish_status":"0","recid":"11783","relation_version_is_last":true,"title":["Promoting Effext of CO2 on the Degradation of Polyethylene to Ethylene and Propylene Over HZSM-5 Catalyst"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T16:22:31.304774+00:00"}
