The reaction was carried out at 300-450°C under 5-40kg/cm2, using a highpressure fixed bed flow system. The (C2=+C3=) selectivity increased in the following order: Zn-Cr/H-ZSM-5<Zn-Cr/Mg-H-ZSM-5<Zn-Cr/Ca-H-ZSM-5 <Zn-Cr/Sr-H-ZSM-5<Zn-Cr/Ba-H-ZSM-5 (Table 1). However, the activity decreased in this order. In order to clarify the effect of CO conversion on the (C2=+C3=) selectivity, the reaction was carried out under various pressures (Fig. 1). The (C2=+C3=) selectivity of the Zn-Cr/Ca-H-ZSM-5 catalyst was about 5% higher than that of the Zn-Cr/H-ZSM-5 catalyst with the same conversion of CO to hydrocarbons (E. Conv.). From these results, it can be concluded that the increase in the (C2=+C3=) selectivity is mainly attributed to the decrease in the catalytic activity of H-ZSM-5 zeolite for olefin hydrogenation when it is modified with alkaline earth metals. Table 2 shows the results of conversion of synthesis gas on the Zn-Cr/Ca-H-ZSM-5 catalyst under various reaction conditions. The (C2=+C3=) selectivity of about 30% was obtained with the CO conversion of about 8%. However, the high (C2=+C3=) selectivity could not be obtained with the high CO conversion.    The direct synthesis of light olefins from synthesis gas was also studied on the composite catalyst composed of an isosynthesis catalyst and the zeolite modified with alkaline earth metals (Table 3). In the case of the ZrO2/Ba•Ca-H-ZSM-5 catalyst, the (C2=+C3=) selectivity of about 23% was obtained with the high CO conversion of about 20%.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"石油学会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0582-4664","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00130954","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"178"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1986-03-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"182","bibliographicPageStart":"178","bibliographicVolumeNumber":"29","bibliographic_titles":[{"bibliographic_title":"石油学会誌"},{"bibliographic_title":"石油学会誌"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.journalarchive.jst.go.jp/japanese/jnlabstract_ja.php?cdjournal=jpi1958&cdvol=29&noissue=2&startpage=178","subitem_relation_type_select":"URI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"JJpnPetrolInst_29_178.pdf","filesize":[{"value":"569.8 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2010271/files/JJpnPetrolInst_29_178.pdf"},"version_id":"318bfaa9-e563-4575-9da8-5a69d7257405"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"30494"},"item_title":"メタノール合成触媒とゼオライト触媒との複合触媒による合成ガスからの低級オレフィンの直接合成","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2010271","relation_version_is_last":true,"title":["メタノール合成触媒とゼオライト触媒との複合触媒による合成ガスからの低級オレフィンの直接合成"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T07:25:29.443100+00:00"}
